c# Mouse events through child control

Question

I have a custom user control that contains a chart element that takes up 80% of the space.

When this is placed in a form, i can click the area not occupied by the chart and the click/mousedown/mouseup events work. But yet when i click in the chart area the mouse events aren't passed through and therefore not triggered.

Is there a global way of doing this without having at add the event function for each control on the form?

    void Drag_MouseDown(object sender, MouseEventArgs e)
    {
        activeControl = sender as UserControl;
        previousLocation = e.Location;
        Cursor = Cursors.SizeAll;
    }

    void Drag_MouseMove(object sender, MouseEventArgs e)
    {
        if (activeControl == null || activeControl != sender)
            return;

        var location = activeControl.Location;
        location.Offset(e.Location.X - previousLocation.X, e.Location.Y - previousLocation.Y);
        activeControl.Location = location;
    }

    void Drag_MouseUp(object sender, MouseEventArgs e)
    {
        activeControl = null;
        Cursor = Cursors.Default;
    }

These are at the moment having to be manually set to both the custom usercontrol and the chart

Answer 1

It seems like chart overrides your mouse events. So, you can try to add event listeners to chart as well.

PS: We can assign same method to different listeners.
