Public Event PageIndexChanging As DataViewPageEventHandler

Event Data

The PageIndexChanging event's data class is DataViewPageEventArgs. The following properties provide information specific to this event:

Property	Description
Cancel	Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs.
NewPageIndex	Gets or sets the selected page’s index.

Remarks

The PageIndexChanging event fires before a specific page is selected. This occurs in the cases listed below:

an end-user tries to switch between pages by clicking the numeric or navigation button;
a new value has been assigned to the ASPxDataViewBase.PageIndex property in code.
one of the client-side methods has been called to change an active page.

You can use the event parameter’s properties to identify a new page index (DataViewPageEventArgs.NewPageIndex) or to cancel the operation by setting the Cancel property to true.

Note

If an end-user clicks the All item in the page size item dropdown, or the All navigation button, the DataViewPageEventArgs.NewPageIndex property returns -1.

After the page index has been changed, the ASPxDataViewBase.PageIndexChanged event is raised.
