Mouseevents of underlying control

Question

0.00/5 (No votes)

See more:

I have a special customized Control which includes another Control in it - in this case a Textbox. The Control itself works like it should ... but not some of the MouseEvents. I like to have not a MouseHover for the Parent-Control and one for the included Control - I like to have the MouseHover only for the Parent , also when the Mouse hovers over the included (Child-) Control. The same for MouseEnter, MouseLeave and MouseMove.
The Prent isn't a real Container - it derives from Control ...

What I have tried:

I tried to catch the Events from (for example) MouseEnter from both Controls (Parent and Child). But this doesn't work well because if I enter the Area of the Child I also leave the Area of the Parent. The final Event should only be raised when entering the Parent. The same for MouseLeave - this Event should only be raised when leaving the Parent but not when entering the Child ...

I tried this but i doesn't work like it should ...

VB

Private Sub Me_MouseLeave(sender As Object, e As EventArgs) Handles Me.MouseLeave, innerTextbox.MouseLeave
    Dim p As Point = Me.PointToClient(MousePosition)
    If Not Me.ClientRectangle.Contains(MousePosition) Then Me.OnMouseLeave(e) : isEntered = False
End Sub

Solution 1

See answers here: c# - Winforms : Intercepting Mouse Event on Main Form first, not on Controls - Stack Overflow[^]

Another option might be to use Application.AddMessageFilter(IMessageFilter)[^]

Hi Rick,
thanks for your Solution - it answers one part of my question ... but sorry ... not the one for MouseEnter / MouseLeave.
The difference is that MouseHover, MouseClick and so on could be hooked and directed to another method which makes a common Event.
The 2 Events from above neutralize each other ... this is the point where I stuck ...
