How to only trigger event when an item is selected (ListView)?

Question

I've been using this property of a ListView :

SelectedIndexChanged

However, it gets triggered also when item is unselected.

What is the best event if I only want event to be triggered when an item is actually selected, and to be called only once? Not twice in a row like ItemActivate .

Answer 1

You can use the SelectedItems.Count property in your ListView , return whenever its 0 , or handle the event if its greater than 0 , so all you need is an if statement in your event handler such as

if(yourListView.SelectedItems.Count == 0)
    return;

//Do your thing

Or:

if(yourListView.SelectedItems.Count > 0){
   //Do your thing
}
