In this article I am going to show how a rectangle's color change as mouse do different.For this application on my window I use a rectangle. Here in rectangle tag we found many property like as mousemove, mouseexit, mouseclick etc.On any event of mouse like as mouseup, mousedown, mouseclick etc. we can perform any type of operation. Here on every different behaviour of mouse I am changing the color of rectangle.

For this I design a window as in window.xml


<window x:class="Mouseoperation.Window1" xmlns="" xmlns:x="" title="Mouseoperation" height="300" width="359">
    <rectangle name="MyRect" height="100" width="300" strokethickness="10" stroke="Blue" fill="Red" mousedown="MyRectMouseDown" mouseenter="MyRectMouseEnter" mouseleave="MyRectMouseLeave" mousewheel="MyRectMouseWheel"></rectangle>

The window will become like as:



Figure 1: Our designing window

This is the window1.xaml.cs code, where we define that how the color of rectangale will change on every different behaviour of Mouse.



using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;

namespace Mouseoperation
    public partial class Window1 : System.Windows.Window
        public Window1()
        void MyRectMouseDown(object sender, System.EventArgs e)
            MyRect.Fill = Brushes.Black;
        void MyRectMouseEnter(object sender, System.EventArgs e)
            MyRect.Fill = Brushes.Aqua;
        void MyRectMouseLeave(object sender, System.EventArgs e)
            MyRect.Fill = Brushes.DarkSeaGreen;

        void MyRectMouseWheel(object sender, System.EventArgs e)
            MyRect.Fill = Brushes.Magenta;
        void MyRectMouseButtonLeft(object sender, System.EventArgs e)
            MyRect.Fill = Brushes.MediumVioletRed;
