How the form can see that I clicked a button on UserControl (so I woud like to see it on Label for example...). I tried to write a special event for it because I think that I do not have any access to Buttons. I thout that by writting event which return a button name I can get it by using Click event on Control and than pass to it the event wroted for UserControl, but when I clicked the button I realized that click event for UserControl is not used (it is handled when I click a Control - not button)

Thanks a lot for solution. Michal.

You can create a custom event on your usercontrol, which you invoke when this button on your UserControl has been pressed.

For instance, create a user-control with a custom event that is called 'ButtonAClicked'.

Then, in your form, you can hook up an event-handler for this event:

myUserControl.ButtonAClicked += new EventHandler ( .... );

In your user-control, you will need to write some code so that this event is raised when Button A has been clicked:

private void ButtonA_Click( object sender, EventArgs e ) {    OnButtonAClick(sender, e); }

The OnButtonAClick method just looks like this:

protected void OnButtonAClick( object sender, EventArgs e ) {    if( ButtonAClicked != null )    {          ButtonAClicked (sender, e);    } }

(Well, this OnButtonAClick method is not that safe / good, note that you should also check whether you'll need to invoke the delegate, or if you can just execute it).
