DataPager.FindPageableItemContainer Method

  • Reference

Definition

Namespace:
System.Web.UI.WebControls
Assembly:
System.Web.Extensions.dll

Retrieves the data-bound control that is associated with the DataPager control.

protected:
 virtual System::Web::UI::WebControls::IPageableItemContainer ^ FindPageableItemContainer();
protected virtual System.Web.UI.WebControls.IPageableItemContainer FindPageableItemContainer ();
abstract member FindPageableItemContainer : unit -> System.Web.UI.WebControls.IPageableItemContainer
override this.FindPageableItemContainer : unit -> System.Web.UI.WebControls.IPageableItemContainer
Protected Overridable Function FindPageableItemContainer () As IPageableItemContainer

Returns

IPageableItemContainer

The data-bound control that is associated with the DataPager control.

Exceptions

InvalidOperationException

A control that implements the IPageableItemContainer interface was not found on the page.

-or-

The control specified by the PagedControlID property does not implement the IPageableItemContainer interface.

-or-

The DataPager control does not have a naming container.

Remarks

The data-bound control retrieved by this method references a data source object that contains the data that the DataPager control pages. For the DataPager control to be able to page this data, the data-bound control must implement the IPageableItemContainer interface.

The FindPageableItemContainer method checks whether the PagedControlID property is set to the ID of a data-bound control. If the PagedControlID property is not set, the FindPageableItemContainer method goes up the stack of naming containers to look for a data-bound control. For example, if the DataPager control is inside the ListView.LayoutTemplate template of a ListView control, the PagedControlID property does not have to be set. This is because the FindPageableItemContainer method can automatically find the ListView control by examining the control tree.
