TextBox ScrollviewerがReadOnlyで機能していない 'True'

Question

TextBoxがReadOnlyのときにScrollViewerが有効になっていないという問題があります。

<TextBox x:Name="txtOmschrijving" IsEnabled="True" Grid.Column="1"HorizontalAlignment="Stretch" Text="{Binding Notification.DescLC}" TextWrapping="Wrap" MaxLength="2500" AcceptsReturn="True" Grid.RowSpan="2"Grid.ColumnSpan="2"ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Visible"TextChanged="TextChanged" LostFocus="txt_LostFocus"/> 

のTextBoxは読み取り専用である後に誰もがScrollViewerのが有効にする方法を知っていますか？

Answer 1
