Hello!

I have some xaml for a control to which I added a xamtilemanager and added 3 xamtiles. The tiles are placed such that the first tile is on the top in row 0 and spans 2 columns. Tile 2 and tile 3 are in the row 1 and in column 0 and 1 respectively. When I make the tile 3 collapsed, I would like tile 2 to span 2 columns and cover the unused space. How do I do this? Here is the xaml for this:

<Grid Name="LayoutRoot" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >

<ig:XamTileManager HorizontalAlignment="Stretch" Name="xamTileMgrCollectionPage" VerticalAlignment="Stretch" >

<ig:XamTileManager.NormalModeSettings>

<ig:NormalModeSettings TileLayoutOrder="UseExplicitRowColumnOnTile" AllowTileSizing="Individual" ShouldAnimate="False"

                                     HorizontalTileAreaAlignment="Stretch" VerticalTileAreaAlignment="Stretch" />

</ig:XamTileManager.NormalModeSettings>

<ig:XamTile ig:XamTileManager.Row="0" ig:XamTileManager.Column="0" ig:XamTileManager.ColumnSpan="2" Name="xamTileRealTimeCtrl" Header="Real Time Trace"/>

<ig:XamTile ig:XamTileManager.Row="1" ig:XamTileManager.Column="0" Name="xamTileVideoCtrl" Header="Video Contols"/>

<ig:XamTile ig:XamTileManager.Row="1" ig:XamTileManager.Column="1" Name="xamTileCollectionCtrl" Header="Collection Controls"/>

</ig:XamTileManager>

</Grid>

After tile 3 is collapsed, the GUI look like in the attachment. And I want  the second tile to stretch horizontally.
