How to: Use a ThicknessConverter Object

Example

This example shows how to create an instance of xref:System.Windows.ThicknessConverter and use it to change the thickness of a border.

The example defines a custom method called changeThickness; this method first converts the contents of a xref:System.Windows.Controls.ListBoxItem, as defined in a separate [!INCLUDETLA#tla_xaml] file, to an instance of xref:System.Windows.Thickness, and later converts the content into a xref:System.String. This method passes the xref:System.Windows.Controls.ListBoxItem to a xref:System.Windows.ThicknessConverter object, which converts the xref:System.Windows.Controls.ContentControl.Content%2A of a xref:System.Windows.Controls.ListBoxItem to an instance of xref:System.Windows.Thickness. This value is then passed back as the value of the xref:System.Windows.Controls.Border.BorderThickness%2A property of the xref:System.Windows.Controls.Border.

This example does not run.
