Hi
I added the following GridButtonColumn
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Any clues?
Thanks

I added the following GridButtonColumn
<
telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete"
ConfirmText="Remove this UDF?" Text="Remove UDF" UniqueName="DeleteColumn">
<HeaderStyle Width="20px" />
</telerik:GridButtonColumn>
and when the application was running I clciked on the delete icon and I got the following error messageMicrosoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.
