Context:

Form / TableLayoutPanel / UserControl

Example handler in the user control:

protected override void OnMouseDown(MouseEventArgs e)
{
    base.OnMouseDown(e);
}

I want to notify the Form that the UserControl intercepted the OnMouseDown event and the form needs to know what Point the user had clicked.

How can I acheive this? Thanks!

Why don't you subscribe for mouse events of `UserControl` in `Form`? – Reza Aghaei Jun 03 '16 at 19:24
@RezaAghaei How do you do that? I ended up using custom event handlers and actions. What you suggest sounds simpler. – Andrew Truckle Jun 04 '16 at 05:40

@AndrewTruckle Custom Event Handlers or Actions are OK too. But since your `UserControl` has a `MouseDown` event, you can handle that event in your form ad put your custom logic there. Handling that event is as simple as handling `Click` event of `Button` or other events like `Load` of `Form`. – Reza Aghaei Jun 04 '16 at 20:05
