Not executing some event

I have listbox and I use "ItemIndexChange" event to do some action, but i do something else when i click on the list ("MouseDown" event).

Events order: "ItemIndexChange", "MouseDown".

How can I prevent executing "ItemIndexChange" when I clicked on the list and execute this event when I use keyboard to navigate throught list items.

Hi,

You can trap the events before they reach your application, you need to overide the function wndproc

protected override void WndProc(ref Message m)
{
switch (m.Msg)
{
case YOUR_EVENT_ID: break;
default: base.WndProc (ref m); break;
}
}

I think the selectedindexchange event Id is 305 or 273, don't remember very well.

Hope this helps,

I thinked about that, but I want to miss ItemIndexChange event which is processed first. I can use flag when I want to miss second event (like in your example).

Just be creative and use a boolean flag or something:

public class MyClass
{
private bool _itemChanged = false;

private void listBox1_ItemIndexChanged( object sender, EventArgs e )
{
_itemChanged = true;
}

private void listBox1_MouseDown( object sender, MouseEventArgs e )
{
if( _itenChanged )
{
// TODO: Add your logic here.
_itemChanged = false;
}
}
}
