Hi, I am using the ListView with check boxes and wish to change the state of a button depending on whether there are any items checked in list or not. I have tried evaluating the ListView.CheckedItems.Count value in the ItemCheck event but unfortunatley the value is not updated at this point, and there is not an AfterItemChecked event. Does anyone know how I can evaluate this immediately an item is checked or unchecked ?

The eventargs gives you NewValue, which will be true id the item is in the prcess of being checked. So if you take ListView.CheckedItems.Count+1, that will give you an accurate value. Hope this helps! Cheers Em
