Form.ControlToPaginate Property

Definition

Gets or sets the control on the form that can be paginated. The default is null (Nothing in Visual Basic). This API is obsolete. For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.

public:
 property System::Web::UI::Control ^ ControlToPaginate { System::Web::UI::Control ^ get(); void set(System::Web::UI::Control ^ value); };
[System.ComponentModel.Bindable(false)]
[System.ComponentModel.Browsable(false)]
public System.Web.UI.Control ControlToPaginate { get; set; }
[<System.ComponentModel.Bindable(false)>]
[<System.ComponentModel.Browsable(false)>]
member this.ControlToPaginate : System.Web.UI.Control with get, set
Public Property ControlToPaginate As Control

Property Value

The control on the form that can be paginated.

Attributes

Examples

The following code example demonstrates how to use the ControlToPaginate property of the Form class to specify which control to paginate.

The example creates a page with two forms. One form has a very long string that on some devices must be paginated to give the user access to the entire text. In order to see the pagination in action, you must view the example on a device that handles pagination. In Visual Studio 2005, you can use one of the device emulators available with the Device Emulator Manager on the Tools menu.

Note

The following code example uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code example must be copied into an empty text file that has an .aspx extension. For more information, see ASP.NET Web Forms Page Syntax Overview.

Remarks

The ControlToPaginate property is used to allow a single control on a form to paginate its contents across several views on mobile devices and providing next and previous navigation between views. A control can paginate its contents even if a containing Panel control has its Paginate property set to false.
