telerik:RadGrid ID="Grid_tblboqmaterial" runat="server" EnableAJAX="True"
AllowAutomaticInserts="True" DataSourceID="SqlDataSource2" GridLines="None" >
The bit in bold comes up with the error "Validation(ASP.NET): Attribute 'EnableAJAX' is not a valid attribute of element 'RadGrid' ".
I have added an AJAX manager and configured the grid to depend on itself and it would appear that AJAX is being used. In my case all I'm trying to do is multiply 2 columns of the active row in the grid and place the result in a 3rd column and with AJAX it is just as slow as doing a full postback. Clearly I am doing something wrong.
Does anybody know what might be the mistake here or can offer a solution that should be quick for this simple calculation?
Thanks in advance
