ListViews SelectedIndexChanged Event Options

[ArunDhaJ]

Hi Friends,

I'm using .Net1.1.
The SelectedIndexChanged event is generated twice when i change the
selection. I think this is because the event is triggered when an
item
loses focus and the other item gains focus.
I want this event to be triggered only once.


Plz help me in solving this problem...


Thanks in advance....

A solution to secondary events is using a flag or similar that lets you detect if the event has been handled or not.

By default the event is raised only once, when the new item gains focus, so
this is unlikely to be the cause. You can check if you have manually
attached a handler to the event. Removing it would be the best solution.

EventHandlers are attached using the syntax: "listView.SelectedIndexChanged
+= new EventHandler(...);".
