# How to: Change the TextWrapping Property Programmatically
## Example  
 The following code example shows how to change the value of the <xref:System.Windows.Controls.TextBlock.TextWrapping%2A> property programmatically.  
  
 Three <xref:System.Windows.Controls.Button> elements are placed within a <xref:System.Windows.Controls.StackPanel> element in [!INCLUDE[TLA2#tla_xaml](../../../includes/tla2sharptla-xaml-md.md)]. Each <xref:System.Windows.Controls.Primitives.ButtonBase.Click> event for a <xref:System.Windows.Controls.Button> corresponds with an event handler in the code. The event handlers use the same name as the <xref:System.Windows.Controls.TextBlock.TextWrapping%2A> value they will apply to `txt2` when the button is clicked. Also, the text in `txt1` (a <xref:System.Windows.Controls.TextBlock> not shown in the [!INCLUDE[TLA2#tla_xaml](../../../includes/tla2sharptla-xaml-md.md)]) is updated to reflect the change in the property.
