Is there an event for when the user unselects a row within a list box?
I'm displaying the number of items that are selected within the listbox. When I'm selecting a row the SelectedIndexChanged event fires and updated the label correctly with the number of items in the SelectedItems array. But when I deselect/unselect no event fires unless I change rows. I need to find a way to do this right when the user deselects/unselects the row.
Thank You

Hi jerry,
You can use SelectedItems.CollectionChanged event and process the Remove action.

Victor,
Thank you so much for the quick reply.
I added this line to my form load and it works.
this.lstVar.SelectedItems.CollectionChanged += new RadListBoxItemCollectionChangedEventHandler(this.lstVar_SelectedItems_Collection_Changed);
Is that the best place to put it?
Thank You
Jerry

Hello jerry,
Currently there is no other place to handle this case. We will add events for deselecting items in a future release. Thank you for the feedback.
