I'm new at this and I'm not sure if I'm even doing it right.
I'm tring to find out if an event has been chosen. I've tried everything and I keep getting CS1502: The best overloaded method match for 'System.Convert.ToString(object)' has some invalid arguments error. My code is:

 <asp:repeater id="parentRepeater" runat="server">
   <itemtemplate><br>

     <span class="week"> <%# DataBinder.Eval(Container.DataItem,"Title") %></span><br><br>


      <!-- start child repeater -->
      <asp:repeater id="childRepeater" datasource='<%# ((DataRowView)Container.DataItem)
      .Row.GetChildRows("myrelation") %>' runat="server" EnableViewState="true">

         <itemtemplate>
<table width="100%"  border="0" cellspacing="5">
  <tr>
    <td width="7%">

<%# CheckEvent(Convert.ToInt32(DataBinder.Eval(Container.DataItem,"[\"EventID\"]")))%>
</td>
<td width="93%"><strong><%# DataBinder.Eval(Container.DataItem,"[\"EventName\"]")%>
      </strong></td>
</tr>
</table>


         </itemtemplate>
      </asp:repeater>
      <!-- end child repeater -->

   </itemtemplate>
</asp:repeater>


I've set up the function as:
public void CheckEvent(int ids) {

//I'm trying to have it check to see if the event was chosen after the page has been submitted.
if(IsPostBack) {

}
}
I've taken everything out of the function, but it still doesn't work. The error comes up at the line the function was called on.

Thanks!

Hi,

I have used a similar nested repeater in my application and it works fine.

The .aspx page is as below:

<asp:Repeater>
      -----
      -----
    <asp:Repeater>
       <itemtemplate>
      ------                                                <input type="hidden" name="Test" value='<%#CheckEvent(DataBinder.Eval(Container.DataItem, "ID")) %>'>
               -------
    </itemtemplate>
   </asp:Repeater>

In the .aspx.cs page I have used the event like this:

protected void CheckEvent(Object Id)
{
     //You can do your conversion here
     //int versionNo = Convert.ToInt32(Id);

     
     if(Page.IsPostBack)
     {
              Response.Write("Yes");
      }
     else
     {
             Response.Write("No");
      }

}

Hope this helps.
