I have a datagrid that contains a column which has an editable drop down list.
I have filtering set to true, but when you place text in the filter box and click "Equal To" or whatever clause, it breaks/errors out
I get Unhandled Exception error. Its a messing popup window with a bunch of jargon.
Anything I need to alter to make this work with that EditTemplate piece in there?
Here is the code
<telerik:GridTemplateColumn HeaderText="ConfirmationType" ItemStyle-Width="240px" AllowFiltering="True" ShowSortIcon="True">
<ItemTemplate>
<%#DataBinder.Eval(Container.DataItem, "ConfirmationType")%>
</ItemTemplate>
<EditItemTemplate>
<telerik:RadComboBox RenderMode="Lightweight" runat="server" ID="RadComboBox1" DataTextField="ConfirmationType" DataValueField="ConfirmationType" DataSourceID="ConfirmationType" SelectedValue='<%#Bind("ConfirmationType") %>'>
</telerik:RadComboBox>
</EditItemTemplate>
</telerik:GridTemplateColumn>
