# How to: Find ControlTemplate-Generated Elements
|
|
This example shows how to find elements that are generated by a <xref:System.Windows.Controls.ControlTemplate>.
|
|
|
|
## Example
|
|
The following example shows a style that creates a simple <xref:System.Windows.Controls.ControlTemplate> for the <xref:System.Windows.Controls.Button> class:
|
|
|
|
[!code-xaml[FindGeneratedItems#CT](~/samples/snippets/csharp/VS_Snippets_Wpf/FindGeneratedItems/CSharp/Window1.xaml#ct)]
|
|
|
|
To find an element within the template after the template has been applied, you can call the <xref:System.Windows.FrameworkTemplate.FindName%2A> method of the <xref:System.Windows.Controls.Control.Template%2A>. The following example creates a message box that shows the actual width value of the <xref:System.Windows.Controls.Grid> within the control template:
|
|
|
|
[!code-csharp[FindGeneratedItems#CTFindElement](~/samples/snippets/csharp/VS_Snippets_Wpf/FindGeneratedItems/CSharp/Window1.xaml.cs#ctfindelement)]
|
|
[!code-vb[FindGeneratedItems#CTFindElement](~/samples/snippets/visualbasic/VS_Snippets_Wpf/FindGeneratedItems/VisualBasic/Window1.xaml.vb#ctfindelement)]
