Definition

Namespace:

System.Web.UI.WebControls

Assembly:

System.Web.dll

Gets a value indicating whether the ObjectDataSourceView object that is associated with the current ObjectDataSource control supports retrieving the total number of data rows, in addition to the set of data.

public:
 virtual property bool CanRetrieveTotalRowCount { bool get(); };

public override bool CanRetrieveTotalRowCount { get; }

member this.CanRetrieveTotalRowCount : bool

Public Overrides ReadOnly Property CanRetrieveTotalRowCount As Boolean

Property Value

Boolean

true, if the operation is supported; otherwise, false.

Remarks

The CanRetrieveTotalRowCount property returns true, if the SelectCountMethod property is set. The method that returns the count should return the total number of rows that can be paged, not the number of rows in a page. Data-bound controls use the total number of rows that can be paged to determine how to render paging controls. For example, how many numeric pager buttons to render in a GridView control pager. For more information on paging support, see EnablePaging.

The CanRetrieveTotalRowCount property is checked during a call to the ExecuteSelect method to ensure that the data source control supports all capabilities requested by setting the various DataSourceSelectArguments properties.
