I am having problems creating a ItemTemplate for a user control.

The following code is what I have roughed out and can't get it to work. I am trying to create an anchor based on the the dataTable I have bound to the the RadRotator.


Here is my template code
Thanks in advance.

public class RotatorTemplate : ITemplate

{

private Control _container;

public void InstantiateIn(Control container)

{

_container = container;

Literal contents =

new Literal();

contents.DataBinding +=

new EventHandler(contents_DataBinding);

container.Controls.Add(contents);

}

private void contents_DataBinding(object sender, EventArgs e)

{

Literal contents = sender

as Literal;

contents.Text =

"<a href=&quot;<%# originalAttribute="href" originalPath="&quot;<%#" originalAttribute="href" originalPath="&quot;<%#" DataBinder.Eval(contents.BindingContainer, &quotDataItem.LinkUrl&quot;)%>&quot; target=&quot;_blank&quot;> <img src=&quotIMG/<%# originalAttribute="src" originalPath="&quotIMG/<%#" originalAttribute="src" originalPath="&quotIMG/<%#" DataBinder.Eval(contents.BindingContainer, &quot;DataItem.ImageUrl&quot;) %>&quot; alt=&quot;&quot; style=&quot;border:0px;&quot/></a>";

}

}

}

Hello,

I noticed in your code (the contents_DataBinding() function) that you are still using the following syntax:

<%# DataBinder.Eval(contents.BindingContainer, "DataItem.LinkUrl")%>

This can only work if your template is defined in an ASP.NET form or user control. Since you are creating your template in the code, you can use the value directly (concatenate it as a string):

contents.Text = "<a href='"+DataBinder.Eval(contents.BindingContainer, "DataItem.LinkUrl")+"'>link</a>";
