    <p>Having trouble with something here which I'm hoping is actually simple.</p> <p>I have a custom UserControl in WPF which allows me to display an image. When the program is running a user can add this UserControl as many times as they like to a canvas. In effect a simple image viewer where they can add and move images about. </p> <p>I would like to be able to right click these images open a contextMenu and then choose send backward of bring forward and the images would then change z order depending which menu choice was clicked.</p> <p>I have the user control set up with the contextMenu so I just need to know the code for changing the z order of this userControl...</p> <p>Any help is much appreciated :)</p> <pre><code>namespace StoryboardTool { /// &lt;summary&gt; /// Interaction logic for CustomImage.xaml /// &lt;/summary&gt; public partial class CustomImage : UserControl { private Point mouseClick; private double canvasLeft; private double canvasTop; public CustomImage() { InitializeComponent(); cusImageControl.SetValue(Canvas.LeftProperty, 0.0); cusImageControl.SetValue(Canvas.TopProperty, 0.0); } public void chooseImage() { OpenFileDialog ofd = new OpenFileDialog(); ofd.Title = "Choose Image to Add"; if (ofd.ShowDialog() == true) { BitmapImage bImage = new BitmapImage(); bImage.BeginInit(); bImage.UriSource = new Uri(ofd.FileName); bImage.EndInit(); image.Width = bImage.Width; image.Height = bImage.Height; image.Source = bImage; image.Stretch = Stretch.Fill; } } private void cusImageControl_LostMouseCapture(object sender, MouseEventArgs e) { ((CustomImage)sender).ReleaseMouseCapture(); } private void cusImageControl_MouseUp(object sender, MouseButtonEventArgs e) { ((CustomImage)sender).ReleaseMouseCapture(); cusImageControl.Cursor = Cursors.Arrow; } private void cusImageControl_MouseMove(object sender, MouseEventArgs e) { if ((((CustomImage)sender).IsMouseCaptured) &amp;&amp; (cusImageControl.Cursor == Cursors.SizeAll)) { Point mouseCurrent = e.GetPosition(null); double Left = mouseCurrent.X - mouseClick.X; double Top = mouseCurrent.Y - mouseClick.Y; mouseClick = e.GetPosition(null); ((CustomImage)sender).SetValue(Canvas.LeftProperty, canvasLeft + Left); ((CustomImage)sender).SetValue(Canvas.TopProperty, canvasTop + Top); canvasLeft = Canvas.GetLeft(((CustomImage)sender)); canvasTop = Canvas.GetTop(((CustomImage)sender)); } else if ((((CustomImage)sender).IsMouseCaptured) &amp;&amp; (cusImageControl.Cursor == Cursors.SizeNWSE)) { /*Point mouseCurrent = e.GetPosition(null); cusImageControl.Height = cusImageControl.canvasTop + mouseClick.Y; cusImageControl.Width = cusImageControl.canvasLeft + mouseClick.X; mouseClick = e.GetPosition(null);*/ } } private void cusImageControl_MouseDown(object sender, MouseButtonEventArgs e) { mouseClick = e.GetPosition(null); canvasLeft = Canvas.GetLeft(((CustomImage)sender)); canvasTop = Canvas.GetTop(((CustomImage)sender)); ((CustomImage)sender).CaptureMouse(); } private void ContextMenuBringForward_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Bring Forward"); } private void ContextMenuSendBackward_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Send Backward"); } private void ContextMenuMove_Click(object sender, RoutedEventArgs e) { cusImageControl.Cursor = Cursors.SizeAll; } private void ContextMenuResize_Click(object sender, RoutedEventArgs e) { cusImageControl.Cursor = Cursors.SizeNWSE; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
