Mouse leave event help required!

[babai28]

Hi,

I have an owned form and a panel in a main window.
I want to run certain code on the mouse leave event of both of them. To be precise:

panel1.Visible=false;

on the mouse leave event of the panel
and

this.Hide();

on the mouse leave event of the owned form.
Both the form and the panel are completely full with a toolstrip (docked to the top) and a listView (docked to fill).
When I did not get the desired result I did put a breakpoint in the methods that run when the mouse leave event of the form and the panel is trigerred. I discovered that the control is not at all entering into the method.
This clearly means the mouse leave event is not at all getting triggered.
Am I missing some property?
Please guide.

Do you have your handlers attached somewhere in your Form.Designer.cs? You should have something like this:

this.MouseLeave += new System.EventHandler(Form_MouseLeave);

But if your panel and form are covered by a ListView, then you should attach your handlers to listView.MouseLeave event, because that's the one that will be fired.

Yeah, I discovered it. If the panel or the form are covered by other controls then the mouse leave event doesnt get fired for the container but the control that fills the container (panel or form). Actually apart from the list view i also have a toolstrip and a treeview in the panel/form and so if the mouse leaves the panel from the treeview side it wont get fired. Neverthless if the mouse leaves the list view and enters the treeview the panel will hide which is again not desired. One work around can be to pad the container (panel or the form) so that inspite of the controls filling them a little area remains exposed and the mouse leave event gets fired. However that may compromise the presentation of the window.
Thank you.
