how do i tie an event to multiple listboxes

Question

i have a piece of code that id like to use for multiple listboxes. basically wherever the mouse is, select that index

driversListBox.SelectedIndex = driversListBox.IndexFromPoint(e.X, e.Y);

how would i write this so that i can tie this code to 2-3 listboxes and the code applies to whoever the sender is?

ive tried casting like below but no luck.

(Listbox)sender.IndexFromPoint(e.X, e.Y);

any help would be appreciated

Answer 1

First hook all the lists to the same event:

list1.MouseMove += CheckMove;
list2.MouseMove += CheckMove;
//...
listN.MouseMove += CheckMove;

Then on the event handler:

var currentList = sender as ListBox;
//Now you can use currentList as it points to the list 
//which fired the event.
