How to: Create a Control That Has an Access Key and Text Wrapping
This example shows how to create a control that has an access key and supports text wrapping. The example uses a xref:System.Windows.Controls.Label control to illustrate these concepts.
Example
Add Text Wrapping to Your Label
The xref:System.Windows.Controls.Label control does not support text wrapping. If you need a label that wraps across multiple lines, you can nest another element that does support text wrapping and put the element inside the label. The following example shows how to use a xref:System.Windows.Controls.TextBlock to make a label that wraps several lines of text.

Add an Access Key and Text Wrapping to Your Label
If you need a xref:System.Windows.Controls.Label that has an access key (mnemonic), use the xref:System.Windows.Controls.AccessText element that is inside the xref:System.Windows.Controls.Label.
Controls such as xref:System.Windows.Controls.Label, xref:System.Windows.Controls.Button, xref:System.Windows.Controls.RadioButton, xref:System.Windows.Controls.CheckBox, xref:System.Windows.Controls.MenuItem, xref:System.Windows.Controls.TabItem, xref:System.Windows.Controls.Expander, and xref:System.Windows.Controls.GroupBox have default control templates. These templates contain a xref:System.Windows.Controls.ContentPresenter. One of the properties that you can set on the xref:System.Windows.Controls.ContentPresenter is xref:System.Windows.Controls.ContentPresenter.RecognizesAccessKey%2A="true", which you can use to specify an access key for the control.
The following example shows how to create a xref:System.Windows.Controls.Label that has an access key and supports text wrapping. To enable text wrapping, the example sets the xref:System.Windows.Controls.AccessText.TextWrapping%2A property and uses an underline character to specify the access key. (The character that immediately follows the underline character is the access key.)
