• Visual Studio 2010 Web Development Improvements

  - by Aamir Hasan

  VS2010 emulates what is available in previous framework versions through reference assemblies. These assemblies contain metadata that describes functionality available in previous versions. VS2010 itself uses the .NET 4 framework, so when adding multitargeting support the team decided against running a previous framework version inside the same process. When your application is compiled to 100 percent guarantee application compatibility, previous compiler versions are used.Web development in Visual Studio 2010 has been enhanced for greater CSS compatibility, increased productivity through HTML and ASP.NET markup snippets and new dynamic IntelliSense JavaScript.Improved CSS CompatibilityHTML and JavaScript SnippetsJavaScript IntelliSense Enhancements

• UpdatePanel, JavaScript postback and changing querystring at same time in SharePoint Search Page

  - by Lee Dale

  Hi Guys, Been tearing my hear out with this one. Let me see if I can explain: I have a SharePoint results page on which I have a Search Results Core WebPart. Now I want to change the parameter in the querystring when I postback the page so that the WebPart returns different results for each parameter e.g. the querystring will be interactivemap.aspx?k=Country:Romania this will filter the results for Romania. First issue is I want to do this with javascript so I call: document.getElementById('aspnetForm').action = "interactivemap.aspx?k=Country:" + country; Nothing special here but the reason I need to call from Javascript is there is also a flash applet on this page from which the Javascript calls originate. When the javascript calls are made the page needs to PostBack but not reload the flash applet. I turned to ASP.Net AJAX for this so I wrapped the search results webpart in an update panel. Now if I use a button within the UpdatePanel to postback the UpdatePanel behaves as expected and does a partial render of the search results webpart not reloading the flash applet. Problem comes because I need postback the page from javscript. I called __doPostBack() as I have used this successully in the past. It works on it's own but fails when I first call the above Javascript before the __doPostBack() (I also tried calling click() on a hidden button) the code for the page is at the bottom. I think the problem comes with the scriptmanager not allowing a partial render when the form post action has changed. My questions are. A) Is there some other way to change the search results webpart parameter without using the querystring. or B) Is there a way around changing the querystring when doing an AJAX postback and getting a partial render. <asp:Content ContentPlaceHolderID="PlaceHolderFullContent" runat="server"> function update(country) { //__doPostBack('ContentUpdatePanel', ''); //document.getElementById('aspnetForm').action = "interactivemap.aspx?k=ArticleCountry:" + country; document.getElementById('ctl00_PlaceHolderFullContent_UpdateButton').click(); } Romania <div class="firstDataTitle"> <div class="datatabletitleOuterWrapper"> <div class="datatabletitle"> <span>Content</span></div> </div> <div class="datatableWrapper"> <div class="dataHolderWrapper"> <div class="datatable"> <div> <div class="searchMain"> <div class="searchZoneMain"> <asp:UpdatePanel runat="server" id="ContentUpdatePanel" UpdateMode="Conditional"> <ContentTemplate> <WebPartPages:webpartzone runat="server" AllowPersonalization="false" title="<%$Resources:sps,LayoutPageZone_BottomZone%>" id="BottomZone" orientation="Vertical" QuickAdd-GroupNames="Search" QuickAdd-ShowListsAndLibraries="false"><ZoneTemplate></ZoneTemplate></WebPartPages:webpartzone> <asp:Button id="UpdateButton" name="UpdateButton" runat="server" Text="Update"/> </ContentTemplate> </asp:UpdatePanel> </div> </div> </div> </div> </div> </div>

• maxlength attribute of a text box from the DataAnnotations StringLength in MVC2

  - by Pervez Choudhury

  I am working on an MVC2 application and want to set the maxlength attributes of the text inputs. I have already defined the stringlength attribute on the Model object using data annotations and it is validating the length of entered strings correctly. I do not want to repeat the same setting in my views by setting the max length attribute manually when the model already has the information. Is there any way to do this? Code snippets below: From the Model: [Required, StringLength(50)] public string Address1 { get; set; } From the View: <%= Html.LabelFor(model => model.Address1) %> <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long" })%> <%= Html.ValidationMessageFor(model => model.Address1) %> What I want to avoid doing is: <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long", maxlength="50" })%> Is there any way to do this?

• MVC2 client/server validation of DateTime/Date using DataAnnotations

  - by Thomas

  The following are true: One of my columns (BirthDate) is of type Date in SQL Server. This very same column (BirthDate) is of type DateTime when EF generates the model. I am using JQuery UI Datepicker on the client side to be able to select the BirthDate. I have the following validation logic in my buddy class: [Required(ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Required")] [RegularExpression(@"\b(0?[1-9]|1[012])[/](0?[1-9]|[12][0-9]|3[01])[/](19|20)?[0-9]{2}\b", ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Invalid")] public virtual DateTime? BirthDate { get; set; } There are two issues with this: This will not pass server side validation (if I enable client side validation it works just fine). I am assuming that this is because the regular expression doesn't take into account hours, minutes, seconds as the value in the text box has already been cast as a DateTime on the server by the time validation occurs. If data already exists in the database and is read into the model and displayed on the page the BirthDate field shows hours, minutes, seconds in my text box (which I don't want). I can always use ToShortDateString() but I am wondering if there is some cleaner approach that I might be missing. Thanks

• How to create a MVC 2 DisplayTemplate for a field whose display format is dependent on another field

  - by Glenn

  If I have a property whose display format is dependent on the value of another property in the view model how do I create a display template for it? The combination of field1's display being dependent on field2's value will be used throughout the app and I would like to encapsulate this in a MVC 2 display template. To be more specific, I've already create a display template (Social.ascx) for custom data type Social that masks a social security number for display. For instance, XXX-XX-1234. [DataType("Social")] public string SocialSecurityNumber { get; set; } All employees also have an employeeID. Certain companies use the employee's social security number as either the whole employee id or as part of it. I need to also mask the employeeID if it contains the social. I'd like to create another display template (EmpID.ascx) to perform this task. [DataType("EmpID")] public string EmployeeID { get; set; } The problem is that I don't know how to get both properties in the "EmpID" template to be able to perform the comparison. Thanks for the help.

• MVC 2 with IIS 6 Problems

  - by SlackerCoder

  Hey guys, I'm using IIS 6 on a Windows 2003 Server and I am trying to get an MVC2 project installed on that machine. I am having nightmare-ish problems doing so! I've looked up TONS of references on what to do, and not 1 single one works. (They work for MVC1 projects, as I have a few of those running already using said solutions). Does anyone have any tips/hints/ideas on what needs to be done for MVC2 projects with IIS 6? I am definitely pulling my hair out over this. I have tried it on 2 of my dev servers, and both get the same result. The closest I can get to a served page is an error page "Object reference not set to an instance of an object", however, the page has try/catch blocks that are being ignored, so I dont think its running the code on the controller, I think it's saying that the controller is the error. (For the reference, the error in question is directed at the HomeController.cs file). What I've tried: Wildcard mapping Changing routes to {controller}.mvc Changing routes to {controller}.aspx Adding the .mvc extension to IIS Modifying routes in Global.asax There's a LOT of code in this project so far, so I will only post the first page(s) that should get served: MASTER PAGE: <div class="page"> <div id="header"> <div id="title"> <h1>Meritain RedCard Interface 2.0</h1> </div> <!-- This is the main menu. Each security role will have access to certain buttons. --> <div id="menucontainer"> <% if (Session["UserData"] != null) { %> <% if (/*User Security Checks Out*/) { %> <ul id="menu"> <li><%= Html.ActionLink("Home", "Index", "Home")%></li> <li><%= Html.ActionLink("Selection", "Index", "Select", new { area = "Selector" }, null)%></li> <li><%= Html.ActionLink("Audit", "Index", "Audit", new { area = "Auditor" }, null)%></li> <li><%= Html.ActionLink("Setup", "Index", "Setup", new { area = "Setup" }, null)%></li> <li><%= Html.ActionLink("About", "About", "Home")%></li> </ul> <% } %> <% } %> </div> </div> <div id="main"> <asp:ContentPlaceHolder ID="MainContent" runat="server" /> <div id="footer"> </div> </div> </div> Default.aspx.cs: [I added this file as a potential solution, since it works with MVC 1] protected void Page_Load(object sender, EventArgs e) { string originalPath = Request.Path; HttpContext.Current.RewritePath(Request.ApplicationPath, false); IHttpHandler httpHandler = new MvcHttpHandler(); httpHandler.ProcessRequest(HttpContext.Current); HttpContext.Current.RewritePath(originalPath, false); } HomeController.cs: public ActionResult Index() { loadApplication(); ViewData["Message"] = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return View(); } private void loadApplication() { Session["UserData"] = CreateUserSecurity(HttpContext.User.Identity.Name.ToString()); } I did not list the CreateUserSecurity method, but all it does it call the DB using the Username and returns the record in the database that matches the username. EDIT: Added code and what I've tried so far (as requested).

• How to configure a GridView CommandField to trigger Full Page Update in UpdatePanel

  - by Frinavale

  I have 2 user controls on my page. One is used for searching, and the other is used for editing (along with a few other things). The user control that provides the search functionality uses a GridView to display the search results. This GridView has a CommandField used for editing (showEditButton="true"). I would like to place the GridView into an UpdatePanel so that paging through the search results will be smooth. The thing is that when the user clicks the Edit Link (the CommandField) I need to preform a full page postback so that the search user control can be hidden and the edit user control can be displayed. Edit: the reason I need to do a full page postback is because the edit user control is outside of the UpdatePanel that my GridView is in. It is not only outside the UpdatePanel, but it's in a completely different user control. I have no idea how to add the CommandField as a full page postback trigger to the UpdatePanel. The PostBackTrigger (which is used to indicate the controls cause a full page postback) takes a ControlID as a parameter; however the CommandButton does not have an ID...and you can see why I'm having a problem with this. Update on what else I've tried to solve the problem: I took a new approach to solving the problem. In my new approach, I used a TemplateField instead of a CommandField. I placed a LinkButton control in the TemplateField and gave it a name. During the GridView's RowDataBound event I retrieved the LinkButton control and added it to the UpdatePanel's Triggers. This is the ASP Markup for the UpdatePanel and the GridView <asp:UpdatePanel ID="SearchResultsUpdateSection" runat="server"> <ContentTemplate> <asp:GridView ID="SearchResultsGrid" runat="server" AllowPaging="true" AutoGenerateColumns="false"> <Columns> <asp:TemplateField> <HeaderTemplate></HeaderTemplate> <ItemTemplate> <asp:LinkButton ID="Edit" runat="server" Text="Edit"></asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField ...... </Columns> </asp:GridView> </ContentTemplate> </asp:UpdatePanel> In my VB.NET code. I implemented a function that handles the GridView's RowDataBound event. In this method I find the LinkButton for the row being bound to, create a PostBackTrigger for the LinkButton, and add it to the UpdatePanel's Triggers. This means that a PostBackTrigger is created for every "edit" LinkButton in the GridView Edit: this did not create a PostBackTrigger for Every "edit" LinkButton because the ID is the same for all LinkButtons in the GridView. Private Sub SearchResultsGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles SearchResultsGrod.RowDataBound If e.Row.RowType = DataControlRowType.Header Then ''I am doing stuff here that does not pertain to the problem Else Dim editLink As LinkButton = CType(e.Row.FindControl("Edit"), LinkButton) If editLink IsNot Nothing Then Dim fullPageTrigger As New PostBackTrigger fullPageTrigger.ControlID = editLink.ID SearchResultsUpdateSection.Triggers.Add(fullPageTrigger) End If End If End Sub And instead of handling the GridView's RowEditing event for editing purposes i use the RowCommand instead. Private Sub SearchResultsGrid_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles SearchResultsGrid.RowCommand RaiseEvent EditRecord(Me, New EventArgs()) End Sub This new approach didn't work at all because all of the LinkButtons in the GridView have the same ID. After reading the MSDN article on the UpdatePanel.Triggers Property I have the impression that Triggers can only be defined declaratively. This would mean that anything I did in the VB code wouldn't work. Any advise would be greatly appreciated. Thanks, -Frinny

• Why updatepanel triggers another updatepanel?

  - by HasanGursoy

  I have two update panels at my ajax page. This is first time I'm using updatepanel and I don't know what is wrong. I think only btnFilter's Click event must trigger the second update panel's content but changing combo values (which also hides/unhides btnFilter button) makes second updatepanel change content (at least I see transferred data with firebug & second updatepanel blinks sometimes). Online here. <asp:UpdatePanel ID="upComparison" runat="server"> <ContentTemplate> Brand: <asp:DropDownList ID="ddlBrands" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlBrands_SelectedIndexChanged" AppendDataBoundItems="true"> <asp:ListItem Value="" Text="Please select a brand..." /> </asp:DropDownList> <asp:Panel ID="pModels" runat="server" Visible="false"> Model: <asp:DropDownList ID="ddlModels" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlModels_SelectedIndexChanged" /> </asp:Panel> <asp:Panel ID="pButton" runat="server" Visible="false"> <asp:UpdateProgress ID="upMain" runat="server" DisplayAfter="100"> <ProgressTemplate><img src="/Assets/Images/loader.gif" /> </ProgressTemplate> </asp:UpdateProgress> <asp:Button ID="btnFilter" runat="server" Text="Filter" OnClick="btnFilter_Click" /> </asp:Panel> </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel ID="upList" runat="server"> <ContentTemplate> <asp:Repeater ID="rProducts" runat="server"> <ItemTemplate>some code here</ItemTemplate> </asp:Repeater> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnFilter" EventName="Click" /> </Triggers> </asp:UpdatePanel>

• UpdatePanel not working in IE or Chrome

  - by gevjen

  I have an updatepanel on my masterpage. Within the contentplace holder I have my update progress control. When a user clicks on the button I load some data into a gridview. This works perfectly in FireFox. User clicks the button, the loading image in my updateprogress fires and loads the gridview. When I test this in IE 6 or 7 or in Chrome. It does a full postback and the updateprogress is never shown. So the updatepanel doesnt seem to be working in these two browsers. Code is below. Again...it works perfect in FireFox. ***From Masterpage *** <asp:UpdatePanel ID="UpdatePanel" runat="server"> <contenttemplate> <asp:contentplaceholder id="holder" runat="server" /> </contenttemplate> </asp:UpdatePanel> **From aspx page **** <asp:UpdateProgress ID="UpdateProgress1" runat="server"> <ProgressTemplate> <img src="ajax-loader.gif" /> </ProgressTemplate> </asp:UpdateProgress>

• Any way for a class to prevent outside code from declaring variables of its type?

  - by supercat

  Is it possible for a class of exposing a type for function returns, without allowing users of that class to create variables of that type? A couple usage scenarios: A Fluent interface on a large class; a statement like "foo=bar.WithX(5).WithY(9).WithZ(19);" would be inefficient if it had to create three new instances of the class, but could be much more efficient if the WithX could create one instance, and the other statements could simply use it. A class may wish to support a statement like "foo[19].x = 9;" even when foo itself isn't an array, and does not hold the data in class instances that can be exposed to the public; one way to do that is to have foo[19] return a struct which holds a reference to 'foo' and the value '19', and has a member property 'x' which could call "foo.SetXValue(19, 9);" Such a struct could have a conversion operator to convert itself to the "apparent" type of foo[19]. In both of these scenarios, storing the value returned by a method or property into a variable and then using it more than once would cause strange behavior. It would be desirable if the designer of the class exposing such methods or properties could ensure that callers wouldn't be able to use them more than once. Is there any practical way to accomplish that?

• Gridview and Modal popup not updating

And in main page bind data using ids in session variable.Gridview - on deleting event i'm deleting that id from session and on deleted event updating both user control using a refresh method (Country1.Refresh()) and gridview panel. But updatepanel is not getting updated and even modalpopup is also not getting refreshed. What could be wrong here? Even though update and refresh events are fired and executed, why is page not getting updated?

• Different users get the same value in .ASPXANONYMOUS

  - by Malcolm Frexner

  My site allows anonymous users. I saw that under heavy load user get sometimes profile values from other users. This happens for anonymous users. I logged the access to profile data: /// <summary> /// /// </summary> /// <param name="controller"></param> /// <returns></returns> public static string ProfileID(this Controller controller ) { if (ApplicationConfiguration.LogProfileAccess) { StringBuilder sb = new StringBuilder(); (from header in controller.Request.Headers.ToPairs() select string.Concat(header.Key, ":", header.Value, ";")).ToList().ForEach(x => sb.Append(x)); string log = string.Format("ip:{0} url:{1} IsAuthenticated:{2} Name:{3} AnonId:{4} header:{5}", controller.Request.UserHostAddress, controller.Request.Url.ToString(), controller.Request.IsAuthenticated, controller.User.Identity.Name, controller.Request.AnonymousID, sb); _log.Debug(log); } return controller.Request.IsAuthenticated ? controller.User.Identity.Name : controller.Request.AnonymousID; } I can see in the log that user realy get the same cookievalue for .ASPXANONYMOUS even if they have different IP. Just to be safe I removed dependency injection for the FormsAuthentication. I dont use OutputCaching. My web.config has this setting for authentication: <anonymousIdentification enabled="true" cookieless="UseCookies" cookieName=".ASPXANONYMOUS" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" /> <authentication mode="Forms"> <forms loginUrl="~/de/Account/Login" /> </authentication> Does anybody have an idea what else I could log or what I should have a look at?

• ASP Classic, SQL 2008, XML Output, and DSN vs DSN-Less Produces Chinese Letters

  - by RoLYroLLs

  I've been having a problem for the past month and can't seem to figure out what is wrong. Here's the setup and a little background. Background: I have a web-host who was running my website on Windows Server 2003 and SQL Server 2000. One of my webpages returned a result set from a stored procedure from the SQL server as xml. Below is the code: Stored Procedure: select top 10 1 as tag , null as parent , column1 as [item!1!column1!element] , column2 as [item!1!column2!element] from table1 for XML EXPLICIT ASP Page: index.asp Call OpenConn Set cmd = Server.CreateObject("ADODB.Command") With cmd .ActiveConnection = dbc .CommandText = "name of proc" .CommandType = adCmdStoredProc .Parameters.Append .CreateParameter("@RetVal", adInteger, adParamReturnValue, 4) .Parameters.Append .CreateParameter("@Level", adInteger, adParamInput, 4, Level) End With Set rsItems = Server.CreateObject("ADODB.Recordset") With rsItems .CursorLocation = adUseClient .CursorType = adOpenStatic .LockType = adLockBatchOptimistic Set .Source = cmd .Open Set .ActiveConnection = Nothing End With If NOT rsItems.BOF AND NOT rsItems.EOF Then OutputXMLQueryResults rsItems,"items" End If Set rsItems = Nothing Set cmd = Nothing Call CloseConn Sub OpenConn() strConn = "Provider=SQLOLEDB;Data Source=[hidden];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" Set dbc = Server.CreateObject("ADODB.Connection") dbc.open strConn End Sub Sub CloseConn() If IsObject(dbc) Then If dbc.State = adStateOpen Then dbc.Close End If Set dbc = Nothing End If End Sub Sub OutputXMLQueryResults(RS,RootElementName) Response.Clear Response.ContentType = "text/xml" Response.Codepage = 65001 Response.Charset = "utf-8" Response.Write "" Response.Write "" While Not RS.EOF Response.Write RS(0).Value RS.MoveNext WEnd Response.Write "" Response.End End Sub Present: All was working great, until my host upgraded to Windows Server 2008 and SQL Server 2008. All of the sudden I was getting results like this: From Browser: From View Source: However, I found that if I use a DSN connection strConn = "DSN=[my DSN Name];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" it works perfectly fine! My current host is not going to support DSN any longer, but that's out of scope for this issue. Someone told me to use an ADO.Stream object instead of a Recordset object, but I'm unsure how to implement that. Question: Has anyone run into this and found a way to fix it? What about that ADO.Stream object, can someone help me with a sample that would fit my code?

• Dynamic Column that contains a Repeater

  - by djbyter

  How would I go about doing this programatically? I can do this just fine declaratively, using a template column and then using something like this: ... <TemplateGridColumn> <ItemTemplate> <div> <asp:Image ID="groupImg" CssClass="groupImg" runat="server"/> <asp:Repeater ID="groupItemRpt" runat="server"> <HeaderTemplate> <ul class="groupItemList"> </HeaderTemplate> <ItemTemplate> <li> <asp:Image ID="itemImg" runat="server" /> <asp:HiddenField ID="itemValue" runat="server" /> </li> </ItemTemplate> <FooterTemplate> </ul> </FooterTemplate> </asp:Repeater> </div> </ItemTemplate> </TemplateGridColumn> ... I am dynamically creating this grid based on the data, so I'm already added columns with one set of controls. But now I need to figure out how to show multiple images, which expand/contract if the groupImg image control is clicked (i just toggle the ul) .. Can anyone point me in the right direction? Thanks.

• Clickonce downloading the deploy files via HTTP and not HTTPS

  - by Scott Manning

  I am working on a project to deploy a project via clickonce. The website where these files are housed will only accept HTTPS traffic and if you attempt to connect via HTTP, our siteminder agent will redirect you to a HTTPS login form. We cannot disable the siteminder agent or enable HTTP for security reasons. In the application file, I have a codebase that references an absolute path to the manifest and it is via HTTPS <dependency> <dependentAssembly dependencyType="install" codebase="https://psaportal.ilab.test.com/testprinting/Application_Files/testprint_1_0_0_1/testprint.exe.manifest" size="10147"> <assemblyIdentity name="testprint.exe" version="1.0.0.1" publicKeyToken="9a078649ee05e0e7" language="neutral" processorArchitecture="msil" type="win32" /> <hash> <dsig:Transforms> <dsig:Transform Algorithm="urn:schemas-microsoft-com:HashTransforms.Identity" /> </dsig:Transforms> <dsig:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> <dsig:DigestValue>2nch1T0SmlAycmePobtg9F1qF7c=</dsig:DigestValue> </hash> </dependentAssembly> </dependency> In running wireshark and decoding the SSL traffic (I am using the server’s private key in wireshark to decrypt the SSL traffic). I see the request to the application’s manifest file is via HTTPS (This is a good thing). But when the clickonce tries to download the testprint.exe.deploy and the other respective files, it is always via HTTP and the siteminder jumps in and redirects the requests which kills the clickonce install with errors. I have tried to specific an absolute codebase reference in the manifest file, but then I start getting entrypoint errors when the manifest is downloaded by the Clickonce installer. The current dependency section from the manifest file looks like the following: <dependency> <dependentAssembly dependencyType="install" allowDelayedBinding="true" codebase="testprint.exe" size="107008"> <assemblyIdentity name="testprint" version="1.0.0.1" language="neutral" processorArchitecture="msil" /> <hash> <dsig:Transforms> <dsig:Transform Algorithm="urn:schemas-microsoft-com:HashTransforms.Identity" /> </dsig:Transforms> <dsig:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> <dsig:DigestValue>dm2nJsu/5UyaEXSDmnISwfnE9MM=</dsig:DigestValue> </hash> </dependentAssembly> </dependency> I have verified that the website where the application, manifest and deploy files are all under the same URL and the SSL certificate is a valid certificate. We have tried about every combination of generating application and manifest files as we a dream up and are looking for other solutions. The application is using .NET 3.5 and we have tried building the application and manifest files via VS2008, VS2010 and mage with no success. Does anyone know how to get all of the deploy files to always download via HTTPS?

• How to read a database record with a DataReader and add it to a DataTable

  - by Olga

  Hello I have some data in a Oracle database table(around 4 million records) which i want to transform and store in a MSSQL database using ADO.NET. So far i used (for much smaller tables) a DataAdapter to read the data out of the Oracle DataBase and add the DataTable to a DataSet for further processing. When i tried this with my huge table, there was a outofmemory exception thrown. ( I assume this is because i cannot load the whole table into my memory) :) Now i am looking for a good way to perform this extract/transfer/load, without storing the whole table in the memory. I would like to use a DataReader and read the single dataRecords in a DataTable. If there are about 100k rows in it, I would like to process them and clear the DataTable afterwards(to have free memory again). Now i would like to know how to add a single datarecord as a row to a dataTable with ado.net and how to completly clear the dataTable out of memory: My code so far: Dim dt As New DataTable Dim count As Int32 count = 0 ' reads data records from oracle database table' While rdr.Read() 'read n records and add them to a dataTable' While count < 10000 dt.Rows.Add(????) count = count + 1 End While 'transform data in the dataTable, and insert it to the destination' ' flush the dataTable after insertion' count = 0 End While Thank you very much for your response!

• click event launched only once problem

  - by user281180

  I have a form in which I have many checkboxes. I need to post the data to the controller upon any checkbox checked or unchecked, i.e a click on a checbox must post to the controller, and there is no submit button. What will be the bet method in this case? I have though of Ajax.BeginForm and have the codes below. The problem im having is that the checkbox click event is being detected only once and after that the click event isnt being launched. Why is that so? How can I correct that? <% using (Ajax.BeginForm("Edit", new AjaxOptions { UpdateTargetId = "tests"})) {%> <div id="tests"> <%Html.RenderPartial("Details", Model); %> </div> <input type="submit" value="Save" style="Viibility:hidden" id="myForm"/> <%} %> $(function() { $('input:checkbox').click(function() { $('#myForm').click(); }); });

• UpdatePanel and ModalPopup Extender

  - by rs

  I have my form designed as <asp:Panel runat="server" Id="xyz"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> 'Gridview with edit/delete - opens detailsview(edit template) with data for editing </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional"> <ContentTemplate> 'Hyperlink to open detailsview(insert template) for inserting records </ContentTemplate> </asp:UpdatePanel> </asp:Panel> <asp:Panel runat="server" Id="xyz1"> 'Ajax modal popup extender control </asp:Panel> It works perfectly when i click update, insert alternately, but when i click insert hyperlink (which is outside gridview) and close/cancel popup without any insert and then again click insert it doesn't call insert_onclick event. It works if i click some other button and click this button. What could be causing this issue and how can i solve it?

• 3 tier application pattern suggestion

  - by Maxim Gershkovich

  I have attempted to make my first 3 tier application. In the process I have run into one problem I am yet to find an optimal solution for. Basically all my objects use an IFillable interface which forces the implementation of a sub as follows Public Sub Fill(ByVal Datareader As Data.IDataReader) Implements IFillable.Fill This sub then expects the Ids from the datareader will be identical to the properties of the object as such. Me.m_StockID = Datareader.GetGuid(Datareader.GetOrdinal("StockID")) In the end I end up with a datalayer that looks something like this. Public Shared Function GetStockByID(ByVal ConnectionString As String, ByVal StockID As Guid) As Stock Dim res As New Stock Using sqlConn As New SqlConnection(ConnectionString) sqlConn.Open() res.Fill(StockDataLayer.GetStockByIDQuery(sqlConn, StockID)) End Using Return res End Function Mostly this pattern seems to make sense. However my problem is, lets say I want to implement a property for Stock called StockBarcodeList. Under the above mentioned pattern any way I implement this property I will need to pass a connectionstring to it which obviously breaks my attempt at layer separation. Does anyone have any suggestions on how I might be able to solve this problem or am I going about this the completely wrong way? Does anyone have any suggestions on how I might improve my implementation? Please note however I am deliberately trying to avoid using the dataset in any form.

• How do I get many, but not all, property values from View to Presenter in WebFormsMvp?

  - by andrej351

  Hey there, What is the best way to get a number of property values of a business object from the View to the Presenter in a WebFormsMvp page? Here is what i propose: The scenario is, I have a business object called Quote which i would like to load form the database, edit and then save. The Quote class has heaps of properties on it. The form is concerned with about 20 of these properties. I have existing methods to load/save a Quote object to/from the database. I now need to wire this all together. So, in the View_Load handler on my presenter i intend to do something like this: public void View_Load(object sender, EventArgs e) { View.Model.Quote = quoteService.Read(quoteId); } And then bind all my controls as follows: <asp:TextBox ID="TotalPriceTextBox" runat="server" Text="<%# Model.Quote.TotalPrice %>" /> All good, the data is on the screen. The user then makes a bunch of changes and hits a "Submit" button. Here is where I'm unsure. I create a class called QuoteEventArgs exposing the 20 properties the form is able to edit. When the View raises the Submit button's event, I set these properties to the values of the controls in the code behind. Then raise the event for the presenter to respond to. The presenter re-loads the Quote object from the database, sets all the properties and saves it to the database. Is this the right way to do this? If not, what is? Cheers, Andrej.

• 2 different routes on one page?

  - by Dejan.S

  Hi I'm pretty new with MVC2 or MVC in general. If it's one thing I get caught up with it's routes. Like now I got this scenario. Im going from the regular site to Admin. My navigation is the same partialview on both I just do a check which data to render something like this. <% if (!Request.RawUrl.Contains("Admin")){%> <% foreach (var site in Model) { %> <%= Html.MenuItem(site.BelongSite, "Sida", "Site", site.BelongSite) %> | <%} %> <%} else {%> <%= Html.ActionLink("Konfig", "Konfigurera", "Admin") %> <% } %> My route looks like this routes.MapRoute( "Admin", // Route name "Admin/{action}/{name}", // URL with parameters new { controller = "Admin", action = "konfigurera", name = UrlParameter.Optional } // Parameter defaults ); On my View called Konfigurera I got Edit sites and they use the route above and it works great. The navigation tho dont get no action assigned to it. It's just <a href='Admin/'> The navigation is in the shared folder, and it is a strongly typed. Any Ideas? I been struggling with this for about a hour now Thanks for any input

• Can Core Data be used for objects with variable schemas?

  - by glenc

  I'm implementing a new iPhone app and am relatively new to Cocoa development overall. I am at the stage of choosing how the persistence layer of this app will work, and it looks like I'm basically choosing between Core Data and sqlite3. The persisted models in this app are intended to have a schema that is loaded at runtime (from some kind of defn file, probably XML). By which I mean, this app is intended to have objects that are user-definable to some extent, e.g. the Customer type (which has certain built-in fields like "name" and "email") can be modified to have extra fields based on the user's specific needs (e.g. a user might want to add a "favourite fruit" field to their Customer type). Having said that, will Core Data work for an app with a non-baked-in data model like this? I've just started playing around with the Core Data object designer thing in XCode and it seems like this thing wants to work with objects that have fixed fields that are compiled in. I'm definitely trying to take the path of least resistance here, and I can see the benefits of using an Apple-supplied data framework, but don't want to start down that path if it's going to lock me into a data model that's defined at compile time.
