I have a user control (ascx) that I have added two public properties to: RequestTypeId and GroupId. Both have the attribute set.
In my aspx page, I have a ListView, and in the ItemTemplate, I place my control reference, like so:
<ctrl:ServiceTypeGroup runat="server" RequestTypeId="<%#RequestType.RequestTypeId%>" GroupId='<%#Eval("Id").ToString()%>' />
Setting the RequestTypeId works fine. Setting the GroupId fails with the following error:
"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
What do I need to do to my user control code to allow binding a Eval() expression to one of its properties? Or is it not possible?
