Event Data

The PageSizeChanged event's data class is EventArgs.


Page size, i.e., the maximum number of rows that can be displayed on a page, is specified by the TreeListSettingsPager.PageSize property.

End-users can change the page size using the page size item of the embedded pager. Additionally, to display all rows, the All navigation button can be used.

The PageSizeChanged event fires on the server side after the page size is changed by end-user interactions and allows you to perform any custom actions.


When ASPxTreeView displays all rows, the TreeListSettingsPager.PageSize property returns the last specified numerical value.
