If you have a RadGrid with a Microsoft checkbox instead of using the RadGrid checkbox column, the column.IsReadOnly is not preventing users from checking the checkbox. It would seem that regardless of the object contain within the column, it should turn prevent editing. For the record, we are not using the Rad checkbox column as we need the user to have one click on that checkbox.
<telerik:GridViewColumn Header="L1" > <telerik:GridViewColumn.CellTemplate> <DataTemplate> <CheckBox Name="ApprovalL1" Click="ApprovalL1_Click" IsChecked="{Binding ApprovalL1, Mode=TwoWay}" /> </DataTemplate> </telerik:GridViewColumn.CellTemplate> </telerik:GridViewColumn>
