Methods

	Name	Description
	CloneField()	This API supports the product infrastructure and is not intended to be used directly from your code. Creates a copy of the current object that is derived from DataPagerField.(Inherited from DataPagerField.)
	CopyProperties(DataPagerField^)	Copies the properties of the current NextPreviousPagerField object to the specified DataPagerField object.(Overrides DataPagerField::CopyProperties(DataPagerField^).)
	CreateDataPagers(DataPagerFieldItem^, Int32, Int32, Int32, Int32)	Creates the user interface (UI) controls for the pager field object and adds them to the specified container.(Overrides DataPagerField::CreateDataPagers(DataPagerFieldItem^, Int32, Int32, Int32, Int32).)
	CreateField()	Creates and returns a new instance of the NextPreviousPagerField class.(Overrides DataPagerField::CreateField().)
	Equals(Object^)	Determines whether the specified object is equal to the current NextPreviousPagerField object.(Overrides Object::Equals(Object^).)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as a hash function for the NextPreviousPagerField class.(Overrides Object::GetHashCode().)
	GetQueryStringNavigateUrl(Int32)	Creates a URL that contains a query string field that has the specified page number.(Inherited from DataPagerField.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	HandleEvent(CommandEventArgs^)	Handles events that occur in the NextPreviousPagerField control and performs the appropriate action.(Overrides DataPagerField::HandleEvent(CommandEventArgs^).)

	SaveViewState()	Saves the changes that were made to the DataPagerField object's view state.(Inherited from DataPagerField.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)
	TrackViewState()	Causes the DataPagerField object to track changes to its view state so that they can be stored in the control's ViewState property and persisted across requests for the same page.(Inherited from DataPagerField.)

Explicit Interface Implementations

	Name	Description
	IStateManager::LoadViewState(Object^)	This API supports the product infrastructure and is not intended to be used directly from your code. Restores view-state information that was saved previously. (Inherited from DataPagerField.)

	IStateManager::TrackViewState()	This API supports the product infrastructure and is not intended to be used directly from your code. Causes the DataPagerField object to track changes to its view state so that they can be stored in the control's ViewState property and persisted across requests for the same page.(Inherited from DataPagerField.)

The NextPreviousPagerField class represents a field that displays navigation controls in a DataPager control. These navigation controls can be used to page through data that are displayed by a control that implements the IPageableItemContainer interface, such as the ListView control.

The NextPreviousPagerField class provides buttons that enable users to navigate through the pages of data one page at a time, or to jump to the first or last page of data.

You can customize the appearance of the NextPreviousPagerField object by using the ButtonCssClass property to set the style of the buttons. You can also use the ButtonType property to choose the type of button that is displayed. The following table lists the available button types.

Button type	Description
Button	A Button control.
Image	An ImageButton control.
Link	A LinkButton control.

You can hide a NextPreviousPagerField object in a DataPager control by setting the Visible property to false. You can also hide the individual buttons (the first-page, previous-page, next-page, and last-page buttons) by setting the ShowFirstPageButton, ShowPreviousPageButton, ShowNextPageButton, and ShowLastPageButton properties to false.

The NextPreviousPagerField control enables you to specify custom text for each button by using the FirstPageText, PreviousPageText, NextPageText, and LastPageText properties.

When the ButtonType property is set to ButtonType.Image, you must provide the URL to an image that will be displayed for the button. You can set images individually for each button by setting the FirstPageImageUrl, PreviousPageImageUrl, NextPageImageUrl, and LastPageImageUrl properties.

When the ButtonType property is set to ButtonType.Image, the corresponding text property acts as the alternate text for the image. For example, the text that is specified by the FirstPageText property is displayed as the alternate text for the first-page image button. In browsers that support tooltips, this text is also displayed as a tooltip.
