Matching vertical layout in different ItemsControls - wpf

Question

I have ListView that uses a GridView to display several columns of data.
Two of the columns have cell templates containing ItemControl's to show a small collection in each cell.
The problem I have is that the vertical size of the ItemControls is not connected in any way since they are in different cells, and therefore they don't line up.
eg:(note this is ONE ROW in the parent listview)
XAML so far:
<ListView Margin="6,6,6,0" ItemsSource="{Binding Controllers}">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem" >
<Setter Property="VerticalContentAlignment" Value="Top" />
</Style>
</ListView.ItemContainerStyle>
<ListView.View>
<GridView>
<!-- snip other columns -->
<GridViewColumn Header="Mode">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding Modes}" DisplayMemberPath="Name"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Parameters">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding Modes}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Blah:" Margin="5,0"/>
<ComboBox>
<ComboBoxItem>Hello</ComboBoxItem>
</ComboBox>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
My first thought was to use a grid as the ItemsPanel of the ItemsControls, so I could use SharedSizeScope on the rows to line them up. However, I can see no way of assigning items dynamically created by the ItemsControl to specific Grid rows.
Can anyone suggest a better solution?

Managed to fix this by setting ListView.ItemContainerStyle.VerticalContentAlignment to Stretch, and then using UniformGrid's for the ItemsControl panels:
Each cell now stretches vertically to match the largest cell, and using UniformGrid splits that vertical size evenly for each item.
eg
<GridViewColumn Header="Mode">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding Modes}" DisplayMemberPath="Name">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="1"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
