We've designed the GridViewItemsSourceProvider
to be easily definable in XAML and we would like to avoid exposing any of RadGridView's methods through it and polluting the class' API unless really necessary.
Exposing a DropDownOpened
event for the RadMultiColumnComboBox
, however, seems reasonable and I have thus logged the following feature request
on your behalf regarding this.
For the time being, however, you can handle the RadDropDownButton.DropDownOpenedEvent
event instead, like so (where mccb
is a reference to your RadMultiColumnComboBox):
this.mccb.AddHandler(RadDropDownButton.DropDownOpenedEvent, new RoutedEventHandler(Button_DropDownOpened));
sender, RoutedEventArgs e)
Please let me know whether this would work for you.
