I'm attempting to add a new record to the grid using the insert button. I have several radcontrols in template columns that show either textboxes or dropdown in edit mode. After clicint insert, I get this error:
Line 76: <telerik:GridTemplateColumn HeaderText="Location Name" UniqueName="tcLocationName" EditFormColumnIndex="6">
Line 77: <EditItemTemplate>
Line 78: <telerik:RadTextBox ID="radtbLocationName" runat="server" InvalidStyleDuration="100" Text='<%# Bind("[Location Name]") %>'
Line 79: Width="115px">
Line 80: </telerik:RadTextBox>
