Label.UseMnemonic Property

Gets or sets a value indicating whether the control interprets an ampersand character (&) in the control's Text property to be an access key prefix character.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
Public Property UseMnemonic As Boolean

Property Value

Type: System.Boolean
true if the label doesn't display the ampersand character and underlines the character after the ampersand in its displayed text and treats the underlined character as an access key; otherwise, false if the ampersand character is displayed in the text of the control. The default is true.

If the UseMnemonic property is set to true and a mnemonic character (a character preceded by the ampersand) is defined in the Text property of the Label, pressing ALT+ the mnemonic character sets the focus to the control that follows the Label in the tab order. You can use this property to provide proper keyboard navigation to the controls on your form.

The following code example demonstrates how to create a Label control that has a three-dimensional border and an image displayed using the ImageList and ImageIndex properties. The control also has a caption with a mnemonic character specified. The example code uses the PreferredHeight and PreferredWidth properties to properly size the Label control on the form on which it is displayed. This example requires that an ImageList has been created and named imageList1 and that it has loaded two images. The example also requires that the code is within a form that has the System.Drawing namespace added to its code.

 Public Sub CreateMyLabel()
     ' Create an instance of a Label. 
     Dim label1 As New Label()

     ' Set the border to a three-dimensional border.
     label1.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D
     ' Set the ImageList to use for displaying an image.
     label1.ImageList = imageList1
     ' Use the second image in imageList1.
     label1.ImageIndex = 1
     ' Align the image to the top left corner.
     label1.ImageAlign = ContentAlignment.TopLeft

     ' Specify that the text can display mnemonic characters.
     label1.UseMnemonic = True 
     ' Set the text of the control and specify a mnemonic character.
     label1.Text = "First &Name:" 

     ' Set the size of the control based on the PreferredHeight and PreferredWidth values. 
     label1.Size = New Size(label1.PreferredWidth, label1.PreferredHeight)

     '...Code to add the control to the form... 
 End Sub
