How to: Create a Custom Panel Element
Example
This example shows how to override the default layout behavior of the xref:System.Windows.Controls.Panel element and create custom layout elements that are derived from xref:System.Windows.Controls.Panel.
The example defines a simple custom xref:System.Windows.Controls.Panel element called PlotPanel, which positions child elements according to two hard-coded x- and y-coordinates. In this example, x and y are both set to 50; therefore, all child elements are positioned at that location on the x and y axes.
To implement custom xref:System.Windows.Controls.Panel behaviors, the example uses the xref:System.Windows.FrameworkElement.MeasureOverride%2A and xref:System.Windows.FrameworkElement.ArrangeOverride%2A methods. Each method returns the xref:System.Windows.Size data that is necessary to position and render child elements.
