I have added an web server control in my solution where I am creating my own datalist. However I am unable to make it get its data. Here is my code in the web server control. What I am doing wrong? Please help!

XML

protected override void RenderContents(HtmlTextWriter writer)
{
    // Place some text before the DataList.
    writer.Write("Here is some text from the RenderContent method.<br>");

    // Call the base RenderContents method.

    this.RepeatDirection = RepeatDirection.Horizontal;
    this.RepeatColumns = _nofcolumns;
    writer.Write("<ItemTemplate> <%# DataBinder.Eval(Container.DataItem, \"Merhaba\")%> </ItemTemplate>");

    base.RenderContents(writer);
}

Thanks in advance!

I'm sorry that I can't help you with that since I don't have great experience in the design of ASP.NET controls. All that I can tell you though is that the method RenderContents should be used to build the HTML output. I think what you are looking for is extending a control that already sports an ItemTemplate tag.

I'm not quite sure of what you're trying to achieve here, but I can point out a serious misconception. Your function RenderContents(HtmlTextWriter) is supposed to render (part of) your control as HTML. This is the stuff that gets sent to the client.
When I look at your writer.Write statement though it seems you want to write out code like it is found on ASPX pages:

aspx

<ItemTemplate> <%# DataBinder.Eval(Container.DataItem, \"Merhaba\")%> </ItemTemplate>"

While this kind of code is fine on ASPX pages that are compiled and run on the server side it has nothing to do with HTML.

Maybe if you explained a little more what it is that you're trying to achieve we could offer even better advice!
