ASP.NET Menu Scrolling (coming in v2010 vol 2)

Thinking Out Loud

ASP.NET AJAX Filter Scrolling

How it works...

As you can imagine, this capability is useful for popup menus that contain large lists. Vertical scrolling of popup menu items can be enabled by displaying specific scroll buttons within popup menus. If scroll buttons are enabled, a popup menu (that does not fit the visible area) automatically adjusts its height to fit the area and displays scroll buttons, allowing popup menu items to be scrolled vertically. To scroll, hover the mouse pointer over a scroll button or click it to scroll faster.

In the ASPxMenu control, scroll buttons can be displayed for all submenus using the menu's EnableSubMenuScrolling property.
In the ASPxPopupMenu, the EnableScrolling property controls the availability of scroll buttons within all popup menus (including the root level menu).
In both menu controls (the ASPxMenu and ASPxPopupMenu), the display of scroll buttons within an individual submenu is controlled by its parent menu item's EnableScrolling property.

When using the ASPxFilterControl, the EnablePopupMenuScrolling property activates vertical scrolling within popup menus.
In addition, descendants which are used as built-in filter controls within the ASPxGridView and ASPxPivotGrid will include similar properties - controlling vertical scrolling availability:
