Handle forms click event when any control clicked on top of the form

Hello,

I would like to create an event handler that is raised when any control is clicked on a form. However I don't want to have to hook up the event handler for each control on the form as this would be hard to maintain. It seems that if a control is placed on top of the form the forms on click event is blocked and only the controls on click event is raised.

So I would be most greatful if anyone knows if there is a way I can make the forms click event fire when I click on any other control on the form?

Thanks,

Caroline

It is quite unusual to have this requirement. It is however easy to implement. For example:

public partial class Form1 : Form {
public Form1() {
InitializeComponent();
wireClick(this.Controls);
}
private void wireClick(Control.ControlCollection ctls) {
foreach (Control ctl in ctls) {
ctl.Click += anyControl_Click;
wireClick(ctl.Controls);
}
}
private void anyControl_Click(object sender, EventArgs e) {
Control ctl = sender as Control;
if (ctl != null) {
// etc...
}
}
}
