  • ASP.NET dropdownlist callback doesn't work inside div

    - by Wayne Werner
    This seems super weird to me. I have a callback handler done in VB which works fine with this code: <!-- Div Outside Form --> <div class="container"> <form id="querydata" runat="server"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler"> <asp:ListItem>Hello</asp:ListItem> <asp:ListItem>Goodbye</asp:ListItem> </asp:DropDownList> <asp:Label runat="server" ID="label1"></asp:Label> </form> </div> <!-- Yep, they're matching --> I can change the value and everything is A-OK, but if I change the code to this (div inside form): <form id="querydata" runat="server"> <!-- Div inside form doesn't work :( --> <div class="container"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler"> <asp:ListItem>Hello</asp:ListItem> <asp:ListItem>Goodbye</asp:ListItem> </asp:DropDownList> <asp:Label runat="server" ID="label1"></asp:Label> </div> </form> It the postback no longer works. Is how asp is supposed to work? Or is it some magic error that only works for me? And most importantly, if asp is not supposed to work this way, how should I be doing this? Thanks!

  • Asp.Net MVC and Entity Framework Architecture

    - by Pino
    Hi, I'm working on a fairly large project at the moment and am currently in the planning stages. I've done a lot of reading into the various patterns suggested for development, somthing that has split the team at the moment is when using Entity Framework should the classes be passed through the applciation layers so that a view accepts an Entity Framework class or should these classes be mapped to BLL Classes and if so at which point (Controller or Library) should this be done? I'm interested in hearing some positives and negitives for each solutions.

  • Dynamic 'twitter style' urls with ASP.NET

    - by Desiny
    I am looking to produce an MVC site which has complete control of the url structure using routing. The specific requirements are: www.mysite.com/ = homepage (home controller) www.mysite.com/common/about = content page (common controller) www.mysite.com/common/contact = content page (common controller) www.mysite.com/john = twitter style user page (dynamic controller) www.mysite.com/sarah = twitter style user page (dynamic controller) www.mysite.com/me = premium style user page (premium controller) www.mysite.com/oldpage.html = 301 redirect to new page www.mysite.com/oldpage.asp?id=3333 = 301 redirect to new page My routes look as follows: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Common", "common/{action}/{id}", new { controller = "common", action = "Index", id = "" } ); routes.MapRoute( "Home", "", new { controller = "Home", action = "Index", id = "" } ); routes.MapRoute( "Dynamic", "{id}", new { controller = "dynamic", action = "Index", id = "" } ); In order to handle the 301 rredirct, I have a database defining the old pages and their new page urls and a stored procdure to handle the lookup. The code (handler) looks like this: public class AspxCatchHandler : IHttpHandler, IRequiresSessionState { #region IHttpHandler Members public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { if (context.Request.Url.AbsolutePath.Contains("aspx") && !context.Request.Url.AbsolutePath.ToLower().Contains("default.aspx")) { string strurl = context.Request.Url.PathAndQuery.ToString(); string chrAction = ""; string chrDest = ""; try { DataTable dtRedirect = SqlFactory.Execute( ConfigurationManager.ConnectionStrings["emptum"].ConnectionString, "spGetRedirectAction", new SqlParameter[] { new SqlParameter("@chrURL", strurl) }, true); chrAction = dtRedirect.Rows[0]["chrAction"].ToString(); chrDest = dtRedirect.Rows[0]["chrDest"].ToString(); chrDest = context.Request.Url.Host.ToString() + "/" + chrDest; chrDest = "http://" + chrDest; if (string.IsNullOrEmpty(strurl)) context.Response.Redirect("~/"); } catch { chrDest = "/";// context.Request.Url.Host.ToString(); } context.Response.Clear(); context.Response.Status = "301 Moved Permanently"; context.Response.AddHeader("Location", chrDest); context.Response.End(); } else { string originalPath = context.Request.Path; HttpContext.Current.RewritePath("/", false); IHttpHandler httpHandler = new MvcHttpHandler(); httpHandler.ProcessRequest(HttpContext.Current); HttpContext.Current.RewritePath(originalPath, false); } } #endregion } It is very simple to look up a user and in fact the above code does this. My problem is in the dynamic / premium part. I am trying to do the following: 1) in the dynamic controller, lookup the username. 2) if the username is in the user list (database), show the Index ActionResult of the Dynamic controller. 3) if the username is not found, look up the username in the premium list 4) if the username is fund in the premium list (database) then show the Index ActionResult of the Preium controller. 5) If all else fails jump to the 404 page (which will ask the user to sign up) Is this possible? Looking up the user twice is a bad idea for performance? How do I do this without redirecting?

  • Problem Paging with Post Action in ASP.NET MVC

    - by Lukasz
    I have a page that takes a number of parameters on a form and posts them to an action. It returns a number of search results that need to be paged through. My pager uses ActionLink; <%= Html.ActionLink(i.ToString(), "Basic", new { page = (i - 1) })%> The results comeback as expected but when I click on page two it goes to the default Action, not the one marked with post. The form values do no get submitted again and the results that are shown for page two are the default results not filters with the parameters. I am not sure how to solve this problem? One way was to save the form values into the database on the post and reading them back on the default action but it seems overkill. Thank You!

  • .Net 2.0 ServiceController.GetServices()

    - by Miles
    I've got a website that has windows authentication enable on it. From a page in the website, the users have the ability to start a service that does some stuff with the database. It works fine for me to start the service because I'm a local admin on the server. But I just had a user test it and they can't get the service started. My question is: Does anyone know of a way to get a list of services on a specified computer by name using a different windows account than the one they are currently logged in with? I really don't want to add all the users that need to start the service into a windows group and set them all to a local admin on my IIS server..... Here's some of the code I've got: public static ServiceControllerStatus FindService() { ServiceControllerStatus status = ServiceControllerStatus.Stopped; try { string machineName = ConfigurationManager.AppSettings["ServiceMachineName"]; ServiceController[] services = ServiceController.GetServices(machineName); string serviceName = ConfigurationManager.AppSettings["ServiceName"].ToLower(); foreach (ServiceController service in services) { if (service.ServiceName.ToLower() == serviceName) { status = service.Status; break; } } } catch(Exception ex) { status = ServiceControllerStatus.Stopped; SaveError(ex, "Utilities - FindService()"); } return status; } My exception comes from the second line in the try block. Here's the error: System.InvalidOperationException: Cannot open Service Control Manager on computer 'server.domain.com'. This operation might require other privileges. --- System.ComponentModel.Win32Exception: Access is denied --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.GetDataBaseHandleWithAccess(String machineName, Int32 serviceControlManaqerAccess) at System.ServiceProcess.ServiceController.GetServicesOfType(String machineName, Int32 serviceType) at TelemarketingWebSite.Utilities.StartService() Thanks for the help/info

But issue is, when my page is getting load dis() is not getting called. I want to run dis() on page load too. I tried google, some blogs suggest the use of Page.RegisterStartupScript Method. But I dont exactly know what is the problem and why we should use this above mentioned method. I would appreciate if someone please tell me why this function is not getting called and how to call it. Edit: I am giving Javascript code also, if it helps. <script type="text/javascript"> function dis() { ValidatorEnable(document.getElementById('<%=RequiredFieldValidator32.ClientID%>'), false); } function en() { ValidatorEnable(document.getElementById('<%=RequiredFieldValidator32.ClientID%>'), true); } </script>

  • Passing data from a View to a controller in ASP.Net MVC

    - by kingrichard2005
    Hello, I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.

  • jquery ui css not loading and creating poblems with asp.net mvc3 page (unexpected token error)

    - by giddy
    hi, So I suspect Im doing something silly, but first off, I can see that my mvc3 project already had jquery ui in it but no theme css files. I needed a date picked and as usual needed to override the EditorFor DateTime. I started off today by just using the default jquery ui js files supplied with the project under scripts. The date picker shows up fine, only with a completed messed up UI based on Site.css. So now I downloaded a build of jquery (with the start theme) and followed this page about how to put it together. Im using T4MVC so my page looks like this: Layout.cshtml : <script src="@Links.Scripts.jquery_1_4_4_js" type="text/javascript"></script> <link href="@Links.Content.Site_css" rel="stylesheet" type="text/css" /> <script src="@Links.Content.start.jquery_ui_1_8_7_custom_css" type="text/javascript"></script> Create.cshtml <script src="@Links.Scripts.jquery_validate_min_js" type="text/javascript"></script> <script src="@Links.Scripts.jquery_validate_unobtrusive_min_js" type="text/javascript"></script> <script src="@Links.Scripts.jquery_ui_1_8_7_custom_min_js" type="text/javascript"></script> And this is the result: Any ideas, Ive been googleing for a while now, I tried a couple combinations of where I put the script and css files tags in different places, but nothing seems to work.

  • Starting with asp.net MVC

    - by Josemalive
    Hello, Actually im doing a home page that only have an action called Index() that returns the view Index.ascx. This index page will be composed by lastest news and lastest registered users, i think that create two partial views is the best idea (this way i could use it in other views). for other hand i have a data access class that calls to database for get stuff (get last news, get last users, etc...) My question is simple, should i call to the this data access class in the Index() action of my HomeController, and add to the ViewData the data obtained? I think that this index() action shouldnt be the responsable of passing this data to the partial views, right? Could you give me a hand? im messing too much? ;-) Thanks in advance. Best Regards. Jose

  • Run SQL Queries on DataTables, or similar, in .Net, without an RDBMS

    - by FastAl
    I'd like to have a dataset or datatables, and be able to run SQL statements on them, without using any external RDBMS. For Example, to take take 2 datatables in a dataset and just join them outright with a SQL statement and Where clause, the result being a new datatable? For example if I have 2 datatables, named People and Addresses in a dataset (that I built using code, not getting from a database .. pardon the old fashioned Join syntax): dim dtJoined as DataTable = MyDataSet.RunSQLQuery ("Select * from People, Orders Where People.PersonID=Orders.OrdereID") Thanks

  • ASP.NET ListView, custom DataSources, and editing items

    - by Andrew Shepherd
    The MSDN walkthroughs provide a number of examples where you can drag a DataSource from the toolbox, run through some simple configuration steps, then drag a ListView onto the screen, point it at the DataSource, and hey - you've got full table editing. Now I'm trying to write my own DataSource class (a class that implements System.Web.UI.IDataSource) and my own DataSourceView class. I now assign an instance of this custom DataSource class to the ListView.DataSource propery. The display of all the items is working well. However, updating, inserting and deleting just is not working. I'm overriding every function I can in my DataSourceView class, and they just aren't being called. This is such a huge topic, I'll focus this question on one simple example: When you press the "Edit" button (the button inside the ItemTemplate with a CommandName of "Edit", you expect the ItemTemplate to be replaced by an EditItemTemplate. This did not happen. The only way I could get it to happen was to handle the onitemediting event. protected void _listViewPublicHolidays_ItemEditing(object sender, ListViewEditEventArgs e) { _listViewPublicHolidays.EditIndex = e.NewEditIndex; _listViewPublicHolidays.DataBind(); } This is hardly a problem, but how come I had to do it at all? In the MSDN walkthroughs where I attach a ListView to a LinqDataSource, this code doesn't have to be written. Can someone who's been here before hazard a guess as to what would be different or missing in my custom datasource?

  • Convert Null Value to String - C#.NET

    - by peace
    foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { PropertyItem.SetValue(this, objDataTable.Rows[0][PropertyItem.Name.ToString()], null); } In one of the loops i get this exceptional error: Object of type 'System.DBNull' cannot be converted to type 'System.String'. The error occurs because one of the fields in the database has no value (null), so the string property could not handle it. How can i convert this null to string? I got this solution If you know a shorter or better one, feel free to post it. I'm trying to avoid checking on every loop is current value is null or not.
