  <asp:Label id="lblSection1" runat="server" text="section1" />
  <asp:RequiredFieldValidator ErrorMessage="Mandatory Field-1" runat="server" ControlToValidate="txtNameSection1" />

server controls inside asp:wizard, doesnt render html when step is not first..

  

I have a server control which consists of a gridview with custom navigation&information capabilities and with javascript functions to highlight the selected grid items or highlight when mouse over event occurs.. (full tested outside asp:wizard)

I'm trying to use that server control inside a template wizard step, when I drop such server control in the first step of the wizard everything goes ok.

When I insert even a blank step previous to the step which contains the server control, the javasript code of the server control is not rendered at all, the page doesn't fail during load but until I go with mouse over an item of the grid for instance.

When I check the rendered HTML I can see no HTML, nor javascript events of this server control where rendered, neither the implementation nor calls to javascript, but even rarer what is there visible in the grid for ie, even the other components of the server control, are not in the "view source code" content.  

I seems it was sent to the client, even showed, but truncated in some phase..

Thanks in advance for your comments,

Louis.


WPF controls won't render

  

I have a problem with rendering WPF controls. The application is basic - just a windows form with a button that opens a WPF window (the actual application is much more complex, but for testing purposes I've created a simple one and it didn't work either).

Now, it works fine on all machines except one particular. As I click the button a new window is opened. This window gets the background of anything that is behind it (you know like a photo, you can see it sometimes when application hangs and you move it) and it won't render its content at all. There is nothing in the window and it looks like the application has hanged, though it's working fine.

One more thing that I want to add, that this stuff started to happen after the OS was upgraded from Vista to Vista SP2.

My first thought was that something is wrong with .net installation, but reinstalling it didn't help.

I've also tried to open a windows form with elementHost in it. The content on the form renders just fine, inside element host it's all empty.


Rendering controls via Loop inside Render

  

I am creatin a server control where
some controls are being rendered inside  `protected override void Render(HtmlTextWriter writer)`

    writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
    writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo1");
    writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button1");
    writer.RenderBeginTag(HtmlTextWriterTag.Input);
    writer.RenderEndTag(); //button
    writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
    writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo2");
    writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button2");
    writer.RenderBeginTag(HtmlTextWriterTag.Input);
    writer.RenderEndTag(); //button       

This way buttons are rendered on design view as well. 
The problem is that number of buttons to render is dynamic based on data in xml file (even if the data was static, the number of button is about 12 and I don't think it is wise to copy paste the same code above 6 times...).

Custom Controls in C# .NET

  
Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

  
Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!
