How do I prevent a column in Silverlight xaml Grid from taking up the entire row? - xaml

Question

I want to display two columns in my Grid. The first is a textblock that is sometimes longer than the row meant to hold it. The second is a button. Is there a way to give the textblock as much room as possible while still leaving room for the button to go immediately after?
When I use the following code, the textblock will sometimes push the button outside the viewable area of the grid.
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Description}" HorizontalAlignment="Stretch" />
<Button Margin="4,0" Height="0" Width="16" Grid.Column="1" MinWidth="20" VerticalAlignment="Center" />
</Grid>
I've tried setting the first column definition Width="*", but then the button is always at the very end of the row, when I want it next to the text. Any suggestions?
This is in Silverlight 4.
Thanks.
EDIT
I want the grid to resize as the user changes the window size, so setting a hard limit on the grid size is no good. That being said, I was able to manually set the MaxWidth in the code behind when the TextBlock loads and when the window changes size. It's clunky, but it works.

Following will surely work..
<Grid x:Name="LayoutRoot" Background="White" Width="250">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock x:Name="textBlock" Grid.Column="0" Text="Text Box" VerticalAlignment="Top"/>
<Button x:Name="button" Grid.Column="1" Content="Button" VerticalAlignment="Top" Width="60"/>
</Grid>
Add Following Line to xaml.cs file in constructor..
public MainPage()
{
InitializeComponent();
textBlock.MaxWidth = LayoutRoot.Width - button.Width;
}
Let me know if there is any issue with it.
Thanks..
