Thank you for writing back.
The described approach does not suggest to validate anything in the CellValueChanged event. In this event you just have to set the row Tag property to a value that we can later use to determine whether or not the row is changed:
sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
Then can validate the data in the RowValidating by checking the Tag property:
sender, Telerik.WinControls.UI.RowValidatingEventArgs e)
//Validate data here
Please let me know if there is something else I can help you with.
