Windows Phone 8 panorama layouts - windows-phone-8

Question

I'm new to Windows phone 8 development and I am having difficulty with a panorama view.
When I create a basic 'Windows Phone Portrait Page' I have no difficulty creating grids and aligning Toolbox controls between those grids.
However, with the Panorama page, when I create grids, those grids are applied to every page in the panorama and therefore I cannot use different layouts for each page.
How would I achieve different layouts on my panorama page?
Should I be using a WindowsPhoneControl instead?
Thanks for your time.

Answer 1

You should define your rows and columns in a Grid control inside a panorama item, instead of defining them in the layout root grid:
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="Transparent">
<!--Panorama control-->
<phone:Panorama Title="My Panorama" >
<!--Panorama item one-->
<phone:PanoramaItem Header="item 1">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="148*"/>
<ColumnDefinition Width="225*"/>
<ColumnDefinition Width="107*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="351*"/>
<RowDefinition Height="201*"/>
<RowDefinition Height="248*"/>
</Grid.RowDefinitions>
</Grid>
</phone:PanoramaItem>
<!--Panorama item two-->
<phone:PanoramaItem Header="item 2">
</phone:PanoramaItem>
</phone:Panorama>
</Grid>
