public:
 property System::Web::UI::WebControls::SqlDataSourceCommandType SelectCommandType { System::Web::UI::WebControls::SqlDataSourceCommandType get(); void set(System::Web::UI::WebControls::SqlDataSourceCommandType value); };
public System.Web.UI.WebControls.SqlDataSourceCommandType SelectCommandType { get; set; }
member this.SelectCommandType : System.Web.UI.WebControls.SqlDataSourceCommandType with get, set
Public Property SelectCommandType As SqlDataSourceCommandType
