Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

Copy 
public:
property bool RetrieveTotalRowCount {
	bool get();
	void set(bool value);
}

Property Value

Type: System::Boolean

true if the data source control should retrieve a total data row count; otherwise, false.

The RetrieveTotalRowCount property supports paging scenarios. Set this property to true to request a total row count from the data source control during the data-retrieval operation. Check the DataSourceView::CanRetrieveTotalRowCount property to determine whether a data source view supports retrieving a total row count. If the data source supports it, the TotalRowCount property is set by the data source control during the course of a data retrieval operation and the total data row count is returned in the TotalRowCount property, much as a value is returned in an output parameter of a method.

System_CAPS_importantImportant

If any of the DataSourceSelectArguments properties are set, but the currently bound data source control does not support the requested capability, an InvalidOperationException exception is thrown when the DataSourceSelectArguments::RaiseUnsupportedCapabilitiesError(DataSourceView^) method is called.
