UserControl events - Not yet answered - Updated: Code added

Question

Hi

I have created a user control that effectively is added to a form as a button group. The control has 3 contained buttons. What I want to do is have my user control raise MouseEnter and MouseLeave events for the entire control. I can get multiple events to fire as the mouse moves over the control from one contained button to the next but what I want is a single mouse enter event and a single mouse leave event for the usercontrol. My buttons completely fill the control container and have no spacing between them. I suppose what I am saying is how can I make the buttons contained in the control "transparent" to the mouse enter and mouse leave events thereby letting these events reach the usercontrol container.

Any ideas?

Thanks

In the attached code I have just about managed to achieve my goal using a timer but it is not good code and there must be a better way of doing this

I have created event handlers for MouseEnter and MouseLeave. I also handle the MouseEnter and MouseLeave events for each contained button in the user control and I can raise the user control MouseEnter and MouseLeave events as the mouse travels from one button to the other. This does not do what I want though. I want to raise a MouseEnter enter event when the mouse enters the user control and a MouseLeave event when the mouse leaves the user control. My 3 buttons are arranged left to right with the tops aligned and no spacing between them. Currently when I move the mouse across the parent form and enter the user control I get a MouseEnter event as the mouse enters the leftmost button. I then get a MouseLeave event as it leaves the first contained button and another MouseEnter event as it enters the second contained button. This is repeated as the mouse moves from the second to the third button. What I am trying to achieve is a mouse enter event once when the mouse enters the user control and a mouse leave event only when it leaves the user control not for each contained control.

This requirement can be achieved by Delegates and Events. First you need to declare an event handler and delegate. Where the implementation for that events should be given in the parent page where the user control is placed.
