Getting the ListView ItemCheck to stop!

Following some SO advice I have tried the following on the ItemCheck event of a ListView control:

private void lstTasks_ItemCheck(object sender, ItemCheckEventArgs e)
    {
     ...some code

     return;
     }

The idea being that that return; will cancel the event

...but does running some code before the blank return; negate the desired result?

I want to use the ItemCheck event because it allows me to pull data via e.Index from the ListView and run some updates. When I return to the ListView the ItemCheck hasn't finished firing and will often crash the program because it can't find the desired index number due to the updates removing that item.

Writing return; will not cancel the event.

Instead, you can set e.NewValue to CheckState.Checked or CheckState.Unchecked.
