Examples

The following example shows how to add a sort descriptor to the DomainDataSource. The data retrieved from the query is sorted by values in the StandardPrice property.

<Grid x:Name="LayoutRoot" Background="White">  
    <riaControls:DomainDataSource x:Name="source" QueryName="GetProducts" AutoLoad="true">
        <riaControls:DomainDataSource.DomainContext>
            <domain:ProductDomainContext />
        </riaControls:DomainDataSource.DomainContext>   
        <riaControls:DomainDataSource.SortDescriptors>
            <riaData:SortDescriptor PropertyPath="StandardCost" Direction="Ascending" />
            <riaData:SortDescriptor PropertyPath="ProductID" Direction="Ascending" />
        </riaControls:DomainDataSource.SortDescriptors>
