使用例

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.textEditor1.StartEditMode()

        Me.textEditor1.Value = "Test"

        ' Select 3 characters starting from character position 1.
        Me.textEditor1.SelectionStart = 1
        Me.textEditor1.SelectionLength = 3

        ' This will print out the selected text which is "est".
        Dim selectedText As String = Me.textEditor1.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.textEditor1.SelectedText = "EST"

        ' SelectAll will select all of the text.
