How to: Create and Use a GridLengthConverter Object
Example
The following example shows how to create and use an instance of xref:System.Windows.GridLengthConverter. The example defines a custom method called changeCol, which passes the xref:System.Windows.Controls.ListBoxItem to a xref:System.Windows.GridLengthConverter that converts the xref:System.Windows.Controls.ContentControl.Content%2A of a xref:System.Windows.Controls.ListBoxItem to an instance of xref:System.Windows.GridLength. The converted value is then passed back as the value of the xref:System.Windows.Controls.ColumnDefinition.Width%2A property of the xref:System.Windows.Controls.ColumnDefinition element.
The example also defines a second custom method, called changeColVal. This custom method converts the xref:System.Windows.Controls.Primitives.RangeBase.Value%2A of a xref:System.Windows.Controls.Slider to a xref:System.String and then passes that value back to the xref:System.Windows.Controls.ColumnDefinition as the xref:System.Windows.Controls.ColumnDefinition.Width%2A of the element.
Note that a separate [!INCLUDETLA#tla_xaml] file defines the contents of a xref:System.Windows.Controls.ListBoxItem.
