Use this component to simplify the interaction between the user interface and data from a DomainContext. After specifying a DomainContext and QueryName, the DomainDataSource can load data and expose it through the Data and DataView properties.

For more information, see DomainDataSource.

The following example shows a DomainDataSource that retrieves data from a domain context named ProductDomainContext and displays the data in a DataGrid control. A query method called GetProducts() must exist on the domain service for the example to work. The DomainDataSource includes two filter descriptors that are connected by a logical AND statement. One filter depends on user input and one filter is specified in the declarative syntax.

<Grid x:Name="LayoutRoot" Background="White">  
    <Grid.RowDefinitions>
        <RowDefinition Height="25" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
    <riaControls:DomainDataSource x:Name="source" QueryName="GetProducts" AutoLoad="true">
        <riaControls:DomainDataSource.DomainContext>

                      RefreshEventName="SelectionChanged" />
              </riaData:FilterDescriptor>
