Have a WPF treeview stretch to fit its container

HI - having problems to achieve the above. My xaml:

 <Grid Margin="5">
     <Grid.Resources>
         <HierarchicalDataTemplate DataType="{x:Type viewmodels:GistViewModel}" ItemsSource="{Binding Path=GistFiles}">
             <TextBlock Text="{Binding GistFiles, Converter={StaticResource GistFilesToFirstFilenameConverter}}"></TextBlock>
         </HierarchicalDataTemplate>
         <DataTemplate DataType="{x:Type viewmodels:GistFileViewModel}">
             <TextBlock Text="{Binding Filename}"></TextBlock>
         </DataTemplate>
     </Grid.Resources>
     <TreeView x:Name="GistsTV" Grid.Column="0" ItemsSource="{Binding Gists}">
     </TreeView>            
 </Grid>

 <Grid Margin="5">
     <Grid.Resources>
         <HierarchicalDataTemplate DataType="{x:Type viewmodels:GistViewModel}" ItemsSource="{Binding Path=GistFiles}">
             <TextBlock Text="{Binding GistFiles, Converter={StaticResource GistFilesToFirstFilenameConverter}}"></TextBlock>
         </HierarchicalDataTemplate>
         <DataTemplate DataType="{x:Type viewmodels:GistFileViewModel}">
             <TextBlock Text="{Binding Filename}"></TextBlock>
         </DataTemplate>
     </Grid.Resources>
     <TreeView x:Name="GistsTV" Grid.Column="0" ItemsSource="{Binding Gists}">
     </TreeView>            
 </Grid>

It results in the attached image. The Treeview is the thin control at the bottom. Any advice?

You can use DockPanel, last element will be filled You don't have columns set though

<Grid.ColumnDefinitions>
</Grid.ColumnDefinitions>

<Grid.ColumnDefinitions>
</Grid.ColumnDefinitions>
