Description

How to cancel changes in invalid GridViewCell and exit edit mode when another control gets the focus.

Solution

To do this, you can subscribe for the GotFocus event of the control that should steal the focus from RadGridView and in the event handler, call the CancelEdit method of RadGridView.

<Grid> 
    <telerik:RadGridView x:Name="radGridView" /> 
    <telerik:RadButton x:Name="cancelEditButton" GotFocus="cancelEditButton_GotFocus"/> 
</Grid> 

private void cancelEditButton_GotFocus(object sender, RoutedEventArgs e) 
{ 
    this.radGridView.CancelEdit(); 
}
