Set height datagrid as height of his stackpanel, for show vertical scrollbar

Question

Hi,
I have this GRID:
<Grid Margin="0,0,0,0">
<Grid.RowDefinitions>
<RowDefinition Height="90" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
In 2° row I have:
<StackPanel Margin="0,0,0,50" Grid.Row="1" Visibility="Hidden" Name="stackPanelSearchResult">
<GroupBox>
<GroupBox.Header>
<Label Style="{StaticResource LabelFieldset}" Content="{StaticResource menuLabelGroupBoxGrid}" />
</GroupBox.Header>
<DataGrid Name="dgPlan"......
</DataGrid>
</GroupBox>
</StackPanel>
</Grid>
How can I set the height of datagrid as hegith of stackpanel for show verticarl scrollbar?
Thanks.

I don't really see you need a stackpanel or a dockpanel or an explicit size on row 1 of your grid unless for some reason you particularly want a fixed size.
You have a perfectly good headered content control there already - a groupbox.
Lose the stackpanel and do:
<GroupBox Margin="0,0,0,50" Grid.Row="1" Visibility="Hidden" Name="stackPanelSearchResult">
<GroupBox.Header>
<Label Style="{StaticResource LabelFieldset}" Content="{StaticResource menuLabelGroupBoxGrid}" />
</GroupBox.Header>
<DataGrid Name="dgPlan"......
</DataGrid>
</GroupBox>
I think it's a bit unusual to put a header on a datagrid, by the way.
Usually a datagrid is kind of the focus of attention and it's obvious what's going to be in it.
I suppose this might be a minor aspect of a complex view though.
Hope that helps.
