Remarks
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.
Examples
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.
