Namespace: DevExpress.Web
Assembly: DevExpress.Web.v18.2.dll
Declaration
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.
