Working with RadBrowseEditor
The events defined in RadBrowseEditor provide an easy way to track user input and perform validation. The example handles such scenario.
Cancel ValueChanging Event
private void radBrowseEditor1_ValueChanging(object sender, ValueChangingEventArgs e)
{
e.Cancel = !File.Exists(e.NewValue.ToString());
}
Private Sub RadBrowseEditor1_ValueChanging(sender As Object, e As Telerik.WinControls.UI.ValueChangingEventArgs)
e.Cancel = Not System.IO.File.Exists(e.NewValue.ToString())
End Sub
