ObjectDataSourceView.CanRetrieveTotalRowCount Property

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

abstract CanRetrieveTotalRowCount : bool with get 
override CanRetrieveTotalRowCount : bool with get

Property Value

Type: System.Boolean
true, if the operation is supported; otherwise, false.

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.
