Determine whether the mouse is over a control? (over a Control pixel range)

.net, bounds, mouse, mouse-position, vb.net

Solution

You need to transform the MousePosition into client coordinates and test the ClientRectangle of the control.

VB.NET

Imports System.Windows.Forms

Public Function MouseIsOverControl(ByVal c As Control) As Boolean
    Return c.ClientRectangle.Contains(c.PointToClient(Control.MousePosition))
End Function

C#

using System.Windows.Forms;

public bool MouseIsOverControl(Control c)
{
    return c.ClientRectangle.Contains(c.PointToClient(Control.MousePosition));
}

Problem

I'm trying to write a function that should determine whether the mouse is over a range in pixels (the pixel range of a specific Control) The problem is that the function only works for the bounds of the `Form`, don't work for buttons or any other control that I've tested ...what I'm missing? ``` ''' <summary> ''' Determinates whether the mouse pointer is over a pixel range of the specified control. ''' </summary> ''' <param name="Control">The control.</param> ''' <returns> ''' <c>true</c> if mouse is inside the pixel range, <c>false</c> otherwise. ''' </returns> Private Function MouseIsOverControl(ByVal [Control] As Control) As Boolean Return [Control].Bounds.Contains(MousePosition) End Function ``` PS: I know the usage of the Mouse events, but this function is for generic usage.
