Partial Public Class MainPage
    Inherits UserControl
    Private currentlocation As Point
    Public Sub New()
        InitializeComponent()
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
        Label1.Content = "您好，" & TextBox1.Text & "!"
    End Sub

    Private Sub LayoutRoot_MouseMove(sender As System.Object, e As System.Windows.Input.MouseEventArgs) Handles LayoutRoot.MouseMove
        currentlocation = e.GetPosition(LayoutRoot)
        Label2.Content = "现在鼠标的坐标是:(" & currentlocation.X.ToString() & "," & currentlocation.Y.ToString() & ")"
    End Sub

    Private Sub LayoutRoot_MouseLeftButtonDown(sender As System.Object, e As System.Windows.Input.MouseButtonEventArgs) Handles LayoutRoot.MouseLeftButtonDown
        MessageBox.Show("您按了左键")
    End Sub

    Private Sub LayoutRoot_MouseRightButtonDown(sender As System.Object, e As System.Windows.Input.MouseButtonEventArgs) Handles LayoutRoot.MouseRightButtonDown
        MessageBox.Show("您按了右键")
    End Sub
End Class

MouseLeftButtonDown和MouseRightButtonDown事件是左键和右键处理事件
