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 NumericPagerField 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 NumericPagerField class.(Overrides DataPagerField::CreateField().)
	Equals(Object^)	Determines whether the specified object is equal to the current NumericPagerField 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 NumericPagerField 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 NumericPagerField object and performs the appropriate action.(Overrides DataPagerField::HandleEvent(CommandEventArgs^).)
	LoadViewState(Object^)	Restores view-state information that was saved previously. (Inherited from DataPagerField.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	OnFieldChanged()	Raises the FieldChanged event.(Inherited from DataPagerField.)
	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::SaveViewState()	This API supports the product infrastructure and is not intended to be used directly from your code. Saves the changes that were made to the DataPagerField object's view state.(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.)
	IStateManager::IsTrackingViewState	This API supports the product infrastructure and is not intended to be used directly from your code. Gets a value that indicates whether the DataPagerField object is tracking its view-state changes.(Inherited from DataPagerField.)

The NumericPagerField class displays navigation controls in a DataPager control. The controls can be used to page through data that is displayed by a control that implements the IPageableItemContainer interface, such as the ListView control. The NumericPagerField object displays page numbers as buttons that users can click to move to specific a page. The control also displays next-page and previous-page buttons that enable users to access more pages of data than the ones that are displayed by the control.

You can customize the appearance of the NumericPagerField object by using the properties that are listed in the following table.

Property	Description
CurrentPageLabelCssClass	The CSS class for the current page number.
NextPreviousButtonCssClass	The CSS class for the next-page and previous-page buttons.
NumericButtonCssClass	The CSS class for the buttons that represent the page numbers.

You can use the ButtonType property to select the type of button that will be displayed. The following table lists the available button types.

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

The controls inside the NumericButtonCssClass object are rendered with non-breaking spaces between them. If you want to customize this behavior, you can use the RenderNonBreakingSpacesBetweenControls property.

You can hide a NumericPagerField object in a DataPager control by setting the Visible property to false. You cannot control the visibility of the next-page and previous-page buttons. They are displayed by the control if the associated data control has additional pages available to display. You can use the ButtonCount property to specify how many buttons are displayed in a NumericPagerField object. Each button corresponds to a page number.

You can set the text of the next-page button by setting the NextPageText property. You can set the text of the previous-page button by using the PreviousPageText property.

When the ButtonType property is set to ButtonType::Image, you must provide the URL of an image that will be displayed for the next-page and previous page buttons. You do this by setting the NextPageImageUrl and PreviousPageImageUrl properties. In that case, the corresponding text property is used as the alternate text for the image. For example, the text that is specified by the NextPageImageUrl property is displayed as the alternate text for the next-page image button. On browsers that support tooltips, this text is also displayed as a tooltip for the corresponding button.
