XAML TextBox: How to keep height fixed even though verticalalignment stretched?

I implemented a custom control which simply contains a label and a textbox to enter multiline text:

<DockPanel Name="MyStackPanel" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" LastChildFill="True" >
<Label DockPanel.Dock="Top" Content="Binding MyTitle" Style="StaticResource PropertyNameLabelStyle" />
<TextBox DockPanel.Dock="Bottom" Text="Binding Path=MyText, Mode=TwoWay" IsReadOnly="Binding MyIsReadOnly" HorizontalAlignment="Stretch" AcceptsReturn="True" Margin="5,5,5,5" VerticalScrollBarVisibility="Visible" IsUndoEnabled="True" />
</DockPanel>


It is important that the TextBox fills all the space its parent has to offer but not more - which is working well with the code above. However if the user types more text than the displayed TextBox offers the TextBox rather becomes bigger (higher) then simply enabling the vertical ScrollBar, which is what I - and I guess most of all other programmers - want.

TextBox

TextBox

TextBox

ScrollBar

I am very new to XAML but I thought you might like to try this:

I set the VerticalAlignment for the TextBox itself:

VerticalAlignment

<TextBox Text="ABC" MinWidth="200" VerticalAlignment="Center">
</TextBox>


It worked for me.
