I have a button with a background. I created mouseenter & mouseleave event. In the mouseleave event, if a mouse cursor is outside of 2 coordinates it will trigger the mouseleave event.

my problem is when i leave in 500X250 rectangle, it will trigger the mouseleave. i want it to trigger in 250X125 rectangle.

What I have tried:

C#

private void Button_SpanMouseEnter(object sender, EventArgs e)
    {
        Button x = sender as Button;
        x.Size = new Size(500, 250);
        x.Location = new Point(0, 0);
    }

    private void Button_SpanMouseLeave(object sender, EventArgs e)
    {
        Button x = sender as Button;

        //If cursor is outside of this coordinates(0,0) & (250,125)
        //it will trigger this size
        x.Size = new Size(250,125);
        x.Location = new Point(0, 0);
    }

WinForm, WPF, ASP.NET, other .. which?

You probably need to rethink your stragegy here. The MouseLeave event is fired when the mouse cursor moves outside the bounds of the control. Therefore a check to determine if the cursor is still within the bounds can never succeed.

Of course. The question makes no practical sense. Besides, changing the size in the handler may recursively invoke the same even, which will lead to a total disaster.

1) Why? 2) What do you mean by "Button"? which one? Full type name, please.

yes. you can have button with background image .

Check for BackgroundImage property of a button.

I think the below solution suits your scenario.

Just put a panel of the size( 250X125 ) you want on the button. Set the backgroundImage property for that panel.

Now since the panel is on the button . You can use Mouseleave event of the panel to fulfill your requirement.

Also, as you mentioned in the question in case of two rectangles, you can use two panels.the outer panel of large size (500X250 rectangle), where as the inner panel (250X125 rectangle.).

Now write the event for Mouse leave of the inner panel. Make sure both panels have same background and inner panel has no borders, so that it appears a single panel for the user.
