  • Display custom error page when file upload exceeds allowed size in ASP.NET MVC2

    - by Marcus
    Hello! My main issue is that I want to display an custom error page when an uploaded file exceeds allowed size (maxRequestLength in web.config). When the big file is uploaded an HttpException is thrown before my upload action method in the controller is invoked. This is expected. I have tried to catch the exception in a custom attribute and also to override OnException in the controller. Why isnt it possible to catch the exception in either the attribute or the OnException method? Its possible though to catch the exception in Application_Error in global.asax but neither Response.Redirect nor Server.Transfer works for redirecting to the custom error page. Server.Transfer gives the "failed to process child request" error and response.redirect gives the "Http headers already sent" error. Any ideas? Thanks in advance! Marcus

  • Objectdatasource always passes 0 and startIndex and pageSize in asp.net 2.0

    - by 101873438432680351218
    I have a DevXpress ASPXGridview, and I am using ObjectDataSource for custom paging. This is my objectDataSource code on aspx page. <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetItems" EnablePaging="true" TypeName="BLL.Item" StartRowIndexParameterName="startIndex" MaximumRowsParameterName="pageSize" SelectCountMethod="GetTotalItems" > <SelectParameters> <asp:ControlParameter ControlID="hfNumber" Name="number" Type="string" /> <asp:ControlParameter ControlID="hfDesc" Name="description" Type="string" /> </SelectParameters> </asp:ObjectDataSource> When I put breakpoints in BLL code, I see that it always executes with startIndex and pageSize as 0. It does pass the other two selectparameters correctly. Also the SelectCountMethod (GetTotalItems) never gets executed.

  • ASP.Net RadioButton loses ViewState

    - by Carl
    I'm having trouble with a simple radio set of two radio buttons (I don't want to use a RadioButtonList [RBL] because RBL doesn't allow child controls, and in my case, if you select one option, I want to enable a textbox next to the button; yes you could hack this with jQuery to move the textbox, but that's dirty!). I would check one, submit the form (either explicitly or through AutoPostBack), and the CheckedChanged event would never fire. When the page was reloaded, both buttons would be unchecked, regardless of their initial state on non-postback load or the state before form submission. I took out the checkbox and stripped this down to the simplest example I could come up with. I tossed EnableViewState=true all over the place just in case it was being disabled somewhere I couldn't find. <form id="form1" runat="server" enableviewstate="true"> <div> <asp:RadioButton ID="foo" Text="foo" runat="server" AutoPostBack="true" OnCheckedChanged="rbChanged" Checked="true" GroupName="foobar" EnableViewState="true" /> <asp:RadioButton ID="bar" Text="bar" runat="server" AutoPostBack="true" GroupName="foobar" OnCheckedChanged="rbChanged" Checked="false" EnableViewState="true" /> <asp:Label runat="server" ID="resultLbl" /> </div> </form> protected void rbChanged(object sender, EventArgs e) { if (foo.Checked) resultLbl.Text = "foo is checked"; else if (bar.Checked) resultLbl.Text = "bar is checked"; else resultLbl.Text = "neither is checked"; }

  • How to access WebMethods in ASP.NET

    - by Quandary
    When i define an AJAX WebMethod like this in an ASPX page (ui.aspx): [System.Web.Services.WebMethod(Description = "Get Import Progress-Report")] [System.Web.Script.Services.ScriptMethod(UseHttpGet = false, ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)] public static string GetProgress() { System.Web.Script.Serialization.JavaScriptSerializer JSONserializer = new System.Web.Script.Serialization.JavaScriptSerializer(); return JSONserializer.Serialize("an Object/Instance here"); } // End WebMethod-Function GetProgress Can I access the description for the corresponding service somewhere ? E.g. when I want to call the webmethod with my own JavaScript, how do I do that ? I investigated the axd files, and found the xmlhttprequest to open ui.aspx/GetProgress But when I type the address in my browser, I get redirected to ui.aspx

  • sorting and paging with gridview asp.net

    - by dangerisgo
    I'm trying to get a gridview to sort and page manually with no success. The problem is that when a user clicks the column they want to sort, it sorts that page, but doesn't sort the datasource (dataview) behind the gridview. So when they progress to a different page, their sort is lost. Pretty much I'm looking for a sort that will actually sort the datasource behind the gridview. Here is what I have so far: protected void GridView_OnSort(object sender, GridViewSortEventArgs e) { String sortExpression = e.SortExpression; if (GridViewSortDirection == SortDirection.Ascending) { DataView myDataView = new DataView(mybll.GetItemsOrdered()); myDataView.Sort = sortExpression + " DESC"; GridView.DataSource = myDataView; GridView.DataBind(); } else { DataView myDataView = new DataView(mybll.GetItemsOrdered()); myDataView.Sort = sortExpression + " ASC"; GridView.DataSource = myDataView; GridView.DataBind(); } } Any help would be appreciated. Thanks.

  • Queryable and BindingSource item add .net

    - by Alexander
    Hello! I wrote my own simple Queryable provider which retrieves data from a database. Now I need to bind this data to a BindingSource and when the new item is added to BindingSource some event or method must be called for handling the add operation. I have tried to implement IBingingList on a List class which is returned when the query is completed, but the AddNew method is not called when the item is added? How can I implement this scenario?

  • ASP.NET MVC POST Parameter into RouteData

    - by David Thomas Garcia
    I'm using jQuery to POST an Id to my route, for example: http://localhost:1234/Load/Delete with a POST Parameter Id = 1 I'm only using the default route in Global.asax.cs right now: routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); When I perform the POST, in my ActionFilter filterContext.RouteData.Values["Id"] is set to the default value of "". Ideally, I'd like it to use the POST Parameter value automatically if the URL comes up with "". I know it is posting properly because I can see the value of "1" in filterContext.HttpContext.Request.Params["Id"]. Is there a way to get RouteData to use a POST parameter as a fall back value?

  • SQL 2000 Not Supported by .NET Framework Data Provider for SQL Server in VS2010's Server Explorer D

    - by Canoehead
    Just tried creating a data connection to a SQL 2000 database in VS2010's Server Explorer using a .NET Framework Data Provider for SQL Server (versus OLE) and found that it didn't work. VS2010 complained that I had to use SQL Server 2005 and up. This used to work in VS2008 (using .NET Framework Data Provider for SQL Server instead of the .NET Framework Data Provider for OLE DB). Is this just a VS2010 restriction or has the ability to connect to SQL 2000 with .NET Framework Data Provider for SQL Server been obsoleted in a post-2.0 version of .NET being used by VS2010? Anyone know why this was done by MS (please don't speculate - I can do that myself ;)?

  • ASP.NET MVC Consume JSONResult in Bing Maps API

    - by rockinthesixstring
    I know there are a few topics on this, but I seem to be fumbling my way through with no results. I'm trying to use a controller to return JSON results to my Bin Maps functions. Here's what I have for my controller (yes it is properly returning JSON data. Function Regions() As JsonResult Dim rj As New List(Of RtnJson)() rj.Add(New RtnJson("135 Bow Meadows Drive, Cochrane, Alberta", "desc", "title")) rj.Add(New RtnJson("12 Bowridge Dr NW, Calgary, Alberta, Canada", "desc2", "title2")) Return Json(rj, JsonRequestBehavior.AllowGet) End Function Then in my script I have this, but it's not working. <script type="text/javascript"> var map = null; var centerLat = 51.045 ; var centerLon = -114.05722; var json_object = $.getJSON("<%: Url.Action("Regions", "Events")%>"); function LoadMap() { map = new VEMap('bingMap'); map.LoadMap(new VELatLong(centerLat, centerLon), 10); $.each(json_object, function () { alert(this.address); //this alert is returning "address is undefined" StartGeocoding(this.address, this.title, this.desc); }); } function StartGeocoding(address, title, desc) { map.Find(null, // what address, // where null, // VEFindType (always VEFindType.Businesses) null, // VEShapeLayer (base by default) null, // start index for results (0 by default) null, // max number of results (default is 10) null, // show results?

  • ASP.Net menu databinding encoding problem

    - by WtFudgE
    Hi, I have a menu where I bind data through: XmlDataSource xmlData = new XmlDataSource(); xmlData.DataFile = String.Format(@"{0}{1}\Navigation.xml", getXmlPath(), getLanguage()); xmlData.XPath = @"/Items/Item"; TopNavigation.DataSource = xmlData; TopNavigation.DataBind(); The problem is when my xml has special characters, since I use a lot of french words. As an alternative I tried using a stream instead and using encoding to get the special characters, with the following code: StreamReader strm = new StreamReader(String.Format(@"{0}{1}\Navigation.xml", getXmlPath(), getLanguage()), Encoding.GetEncoding(1254)); XmlDocument xDoc = new XmlDocument(); xDoc.Load(strm); XmlDataSource xmlData = new XmlDataSource(); xmlData.ID = "TopNav"; xmlData.Data = xDoc.InnerXml; xmlData.XPath = @"/Items/Item"; TopNavigation.Items.Clear(); TopNavigation.DataSource = xmlData; TopNavigation.DataBind(); The problem I'm having now is that my data doesn't refresh when I change the path where the stream gets read. When I skip through the code it does, but not on my page. So the thing is either, how do I get the data te be refreshed? Or (which is actually preferred) how do I get the encoding right in the first piece of code? Help is highly apreciated!

  • Asp.Net Mvc JQuery ajax input parameters are null

    - by Dofs
    Hi, I am trying to post some data with jQuery Ajax, but the parameters in my Ajax method are null. This is simple test to send data: var dataPost = { titel: 'titel', message: 'msg', tagIds: 'hello' }; jQuery.ajax({ type: "POST", url: "Create", contentType: 'application/json; charset=utf-8', data: $.toJSON(dataPost), dataType: "json", success: function(result) { alert("Data Returned: "); } }); And my Ajax method looks like this: [HttpPost] public ActionResult Create(string title, string message, string tagIds) {... } There is something basic wrong with the data I send, but I can't figure out what. All the time the title, message and tagIds are null, so there is something wrong with the encoding, I just don't know what. Note: The jQuery.toJSON is this plugin

Please could someone help me in constructing a proper unordered list based on my depth,itemid coulumns? Thanks.

  • Posting a form and redirecting to action ASP.NET MVC

    - by dean nolan
    I have a navigation bar that uses JQuery to move between 4 stages of signup process. However I need to make sure everything is working with JS disabled. So I have these 4 link images at the bottom of the page and I need so that if one is clicked it posts to the current action so I can save all the form data and then redirect to the next stage. The redirect is easy enough as I will just pass a parameter in the route or form but I don't know how to post the method using just action links. I could put 4 different submit buttons with different classes for the image backgrounds etc but this feels wrong. Any ideas?

  • System.Net.Mail.MailMessage Raw Content / Spam Assassin

    - by Martin
    Hey everyone, What I am trying to do is pass the raw content of an outgoing email to spamassassin in order to calculate a spam score. I am stuck in how I might get the raw content of the email. My C# code currently just constructs the MailMessage and passes it the SmtpClient's Send() method. Before sending, is there a way to get a raw version of the mail message (as the protocol might see it) so that I can pass this to the spamassassin tool for spam assessment? If I've not explained very well, let me know and I'll try to explain better. Thanks in advance, Martin.
