This may have been answered already but I can't seem to track anything down on it. I have a XamGrid that contains a ComboBoxColumn. I'd like to bind the ComboBoxColumn to a DomainDataSource. I've added the DomainDataSource as a resource but I can't seem to get the binding to work correctly. Here's some of my XAML that hopefully shows what I'm trying to accomplish:

<Grid x:Name ="LayoutRoot">

<Grid.Resources >

<riaControls:DomainDataSource AutoLoad="True" x:Key="dsDiv" x:Name="dsDiv" QueryName

="GetNewDeptDivisionsSelect">

<riaControls:DomainDataSource.DomainContext >

<my:NewDomainContext />

</riaControls:DomainDataSource.DomainContext >

<riaControls:DomainDataSource.QueryParameters >

<riaControls:Parameter ParameterName="DepartmentID" Value ="0" />

</riaControls:DomainDataSource.QueryParameters >

</riaControls:DomainDataSource >

<riaControls:DomainDataSource AutoLoad="True" x:Key="dsSect" x:Name="dsSect" QueryName ="GetNewDeptSectionsSelect">

<riaControls:DomainDataSource.DomainContext >

<my:NewDomainContext />

</riaControls:DomainDataSource.DomainContext >

<riaControls:DomainDataSource.QueryParameters >

<riaControls:Parameter ParameterName="DepartmentID" Value="0" />

</riaControls:DomainDataSource.QueryParameters>

</riaControls:DomainDataSource>

</Grid.Resources>

...and in my grid:

<ig:XamGrid x:Name="ItemGrid" DeleteKeyAction="DeleteSelectedRows" AutoGenerateColumns="False" ItemsSource="{Binding Data, ElementName=dsItem}" Width="900" Height="430">
