Visual Basic

Private Sub Button1_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ' Make sure the editor is in edit mode. The following operations
    ' are only valid during edit mode. You can set IsAlwaysInEditMode
    ' to True so this step is not necessary as the editor will always
    ' be in edit mode.
    Me.maskedEditor1.StartEditMode()

    ' Select 3 characters starting from character position 4.
    Me.maskedEditor1.SelectionStart = 4
    Me.maskedEditor1.SelectionLength = 3

    Dim selectedText As String = Me.maskedEditor1.SelectedText
    Debug.WriteLine("SelectedText = " & selectedText)

    ' Setting the SelectedText will delete the selected text
    ' and in its place insert the specified text. If nothing
    ' is currently selected then the specified text will be 
    ' inserted at the caret location.
    Me.maskedEditor1.SelectedText = "222"

    ' SelectAll will select all of the text.
    Me.maskedEditor1.SelectAll()

    ' The following two lines perform the same operation as SelectAll.
    ' TextLength property returns the number of display characters 
    ' (character placeholders) in the masked editor, regardless of whether
    ' they are empty or filled in.
