ASPxGridView - Implement virtual paging functionality

created 17 years ago

ASPxGridView needs to support virtual scrolling. This feature helps vertical scrolling- only the first page of results are loaded, and when the user scrolls down, the grid should use AJAX to load another page. If the user keeps scrolling down, then this process repeats. This is more user friendly than using the arrows at the button of the page.
An example can be seen here: http://www.telerik.com/demos/aspnet/Grid/Examples/Programming/WebMailGrid/DefaultCS.aspx
Proposed Solution:
Make a vertical scrollbar function exactly like the paging arrows at the bottom of the grid. When the user has scrolled through an entire page of records, use AJAX to load the next page.

    The Settings.VerticalScrollBarStyle property has been added. enum GridViewVerticalScrollBarStyle { Standard, Virtual }.
    To enable this feature you will have to set Settings.VerticalScrollBarStyle to "Virtual" and Settings.ShowVerticalScrollBar to "true".
    Note:
    You may want to change Settings.VerticalScrollableHeight and SettingsPager.PageSize properties as well.
    Thank you,
    Andrew R&D.
