Silverlight - Expander Control with ListBox, 100% Height - silverlight

Im trying to put 4 expander controls inside a Grid with 4 rows, the expander control contains a Grid and a ListBox (Currently holding some sample data).
Ideally when an expander is expanded I want it to fill all the available space without pushing the remaining expanders off the screen or the list box going off the screen. Can anyone think of a way of adapting the XAML below or updating the XAML below to achieve this?
<Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource ExpanderData}}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="0.246*"/>
<RowDefinition Height="0.754*"/>
</Grid.RowDefinitions>
<Grid Margin="0" Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.275*"/>
<ColumnDefinition Width="0.725*"/>
</Grid.ColumnDefinitions>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<toolkit:Expander x:Name="Expander1" Header="One" IsExpanded="False">
<Grid Background="#FFE5E5E5">
<ListBox Margin="0" ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Collection}"/>
</Grid>
</toolkit:Expander>
<toolkit:Expander x:Name="Expander2" Header="Two" IsExpanded="True" VerticalAlignment="Top" Grid.Row="1">
<Grid Background="#FFE5E5E5">
<ListBox Margin="0" ItemTemplate="{StaticResource ItemTemplate1}" ItemsSource="{Binding Collection}"/>
</Grid>
</toolkit:Expander>
<toolkit:Expander x:Name="Expander3" Header="Three" VerticalAlignment="Top" Grid.Row="2" IsExpanded="False">
<Grid Background="#FFE5E5E5">
<ListBox Margin="0" ItemTemplate="{StaticResource ItemTemplate2}" ItemsSource="{Binding Collection}"/>
</Grid>
</toolkit:Expander>
<toolkit:Expander x:Name="Expander4" Header="Four" VerticalAlignment="Top" Grid.Row="3" IsExpanded="False">
<Grid Background="#FFE5E5E5">
<ListBox Margin="0" ItemTemplate="{StaticResource ItemTemplate3}" ItemsSource="{Binding Collection}"/>
</Grid>
</toolkit:Expander>
</Grid>
</Grid>
</Grid>
</Grid>
</UserControl>

I'd probably use a DockPanel instead of a Grid - for Silverlight you'll have to get it from the Silverlight Toolkit (http://silverlight.codeplex.com) - I know you already have it, I'm just referencing it for the archives. Uncheck the "LastChildFill" property and dock all the children to Top.
It's tough to test without adequate data, but what if you just had one Expander open at a time and set the MaxHeight of each Expander to the remaining available space?

WPF - Making ONE control stretch vertically

I'm new to WPF/XAML and with a few hours I got a GUI that is presentable except for one thing. I got the controls to resize horizontally with the window but I cannot figure out what I'm missing to do the same vertically. I want only the DataGrid control to stretch vertically. The Datagrid control is not getting the hint. What am I missing?

A Grid will expand to fill its parent. You can use the root level grid in your window, if you won't be adding any more content.
To put two controls in a grid one above the other, define rows, and don't neglect to add the Grid.Row="..." attribute to the child controls to determine which grid rows they'll be in, or else they'll be superimposed on one another.
<Grid Margin="0,0,-0.2,0.2">
<Grid.RowDefinitions>
<!-- Height="*" -> Fill all space not taken up by other rows -->
<RowDefinition Height="*" />
<!-- Height="Auto" -> Fill space required by content -->
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<DataGrid
Grid.Row="0"
x:Name="dataGrid"
Margin="10,10,10,0"
IsReadOnly="True"
TextBlock.FontSize="16"
/>
<TextBox
Grid.Row="1"
x:Name="Interpretation"
Height="100"
MinHeight="100"
Margin="10,10,10,0"
IsReadOnly="True"
Text="Interpretation of Results"
TextAlignment="left"
TextBlock.FontSize="20"
TextWrapping="Wrap"
/>
</Grid>
If you've got a series of auto-sized children that'll be adjacent, it can be simpler to make one row a StackPanel:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<DataGrid
Grid.Row="0"
...
/>
<StackPanel
Grid.Row="1"
Orientation="Vertical"
>
<Label>Stuff</Label>
<TextBox ... />
<Label>More Stuff</Label>
<TextBox ... />
</StackPanel>
</Grid>
You put it in a stackpanel.
Stackpanels only ever grow to the size their contents need, you should use Grid instead, grids and their cells will fill their container.

I want the listview height to be auto, but as soon as I populate with some data , the listview height is set to 525. I want to to be auto. How can I achieve this

WPF DataGrid not showing scrollbars and running out of visible area

Like others I have a DataGrid that is not showing scrollbars. What I think is unique to my situation is that I do not see a StackPanel anywhere in the visual or logical tree. I am using WPF Inspector to view the trees. I have tried various suggestions to set the height and width of the containing Grid columns and rows with no success. I'm certain there is something I'm missing that is allowing the content to extend beyond the visible area but I cannot tell what it is yet. Any help would be appreciated. This application is a WPF Prism with MEF app and the DataGrid is within a UserControl which is in a Prism region.

You have the DataGrid in a Grid row where the RowDefinition Height is auto so the grid will be measured with an infinite height and be arranged to its DesiredSize.Height and never show scrollbars. Seems like the grid should be in row 1 or make the height of row 2 to be * instead of auto.

How to have one control expand/fill up to maxheight, then expand/fill another control in WPF?

I have the following XAML source to demonstrate what I am working on.
I want, when resizing the group vertically, is to have the first groupbox expand, up to its max height, then, when that is reached, expand the third groupbox.The third groupbox has a min height property, as well.
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" x:Name="Screen_1_Name"
x:Class="TestExpansionScreens.Screen_1"
Width="400" Height="400">
<Grid x:Name="LayoutRoot" Background="White" Margin="0,0,0,0">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<GroupBox Header="Thing1" Background="LightGreen" Grid.Row="0" Grid.Column="0" MaxHeight="350">
<Button Content="Stuff1" />
</GroupBox>
<GroupBox Header="Thing2" Background="LightBlue" Grid.Row="1" Grid.Column="0">
<TextBox Text="Stuff2" Height="60" />
</GroupBox>
<GroupBox Header="Thing3" Background="Pink" Grid.Row="2" Grid.Column="0">
<TextBox Text="Stuff3" />
</GroupBox>
</Grid>
</UserControl>
Normally, when I just want a single control expanded to fill the available space, I use a DockPanel. I've built this example with all kinds of assortments of grids and dockpanels, however, I have been unable to resolve how to make it work. Any idea on how to make it happen?
Thanks
You have to set the MaxHeight on your first RowDefinition, not on the GroupBox. The row will grow up to that height and then all excess space will be occupied by the third row. You can also add a MinHeight to the third row.
<Grid x:Name="LayoutRoot" Background="White" Margin="0,0,0,0">
<Grid.RowDefinitions>
<RowDefinition MaxHeight="350" />
<RowDefinition Height="Auto"/>
<RowDefinition MinHeight="150" />
</Grid.RowDefinitions>
<GroupBox Header="Thing1" Background="LightGreen" Grid.Row="0" Grid.Column="0">
<Button Content="Stuff1" />
</GroupBox>
<GroupBox Header="Thing2" Background="LightBlue" Grid.Row="1" Grid.Column="0">
<TextBox Text="Stuff2" Height="60" />
</GroupBox>
<GroupBox Header="Thing3" Background="Pink" Grid.Row="2" Grid.Column="0">
<TextBox Text="Stuff3" />
</GroupBox>
</Grid>

Silverlight PivotItem not scrolling down

PivotItem can't scroll down... Anyone has any ideas as to how I can remedy this?
For whatever the reason just won't scroll down when content that is bound inside the listbox is longer than the height of the page. I tried adding a grid inside the pivotitem with height set to auto, but to no avail.
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
</Grid.RowDefinitions>
<controls:Pivot Height="Auto">
<controls:PivotItem Header="Main Information">
<Border CornerRadius="10" Background="#FF5C7590" Height="Auto" Padding="2" BorderThickness="1">
<ListBox x:Name="lbxPropertyItems">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Margin="5, 0, 0, 0" Grid.Column="0" Text="{Binding Label}" />
<TextBlock Grid.Column="1" Text="{Binding Value}" TextWrapping="Wrap" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Border>
</controls:PivotItem>
</controls:Pivot>
</Grid>
Thanks for any advice.
The issue is that a StackPanel has an infinite layout space in which ever orientation it is set, so the ScrollViewer included in the ListBox never gets activated in that direction. The best way to handle it is to host it inside a Grid control with row or column definitions.
