# How to: Define a GroupBox Template
This example shows how to create a template for a <xref:System.Windows.Controls.GroupBox> control.  
  
## Example  
 The following example defines a <xref:System.Windows.Controls.GroupBox> control template by using a <xref:System.Windows.Controls.Grid> control for layout. The template uses a <xref:System.Windows.Controls.BorderGapMaskConverter> to define the border of the <xref:System.Windows.Controls.GroupBox> so that the border does not obscure the <xref:System.Windows.Controls.HeaderedContentControl.Header%2A> content.
