Previously focused control

[HJo]

Hi all, I wonder if there is some way to find out which control had input focus previously to an other... I.e. from a btn_Click(...) event handler, I want to know which control had focus before the user clicked the button. Thanks in advance, /Henrik J.

You can save the last focused control in the Leave event method: private Control lastControl; private void allControls_Leave(object sender, EventArgs e){ lastControl = (Control)sender; }

That should do the trick! But how do I add the Leave event to all controls? Do I have to loop through all controls and add it one by one, or is is possible to add an event to a collection? (Doesn't seem to be possible with ControlsCollection) Thanks! /Henrik
