Whenever I enter search criteria and execute the search the first time the data appears in the grid control correctly. Because the results return a cursor with a lot of records the scrollbar is active and the scrollbox displays. However, if I click back on the first tab and re-execute the same query and return the same cursor, the scrollbar is disabled and the scrollbox disappears.

Ken,

Vlad Grynchyshyn did some research on that topic and wrote an article: http://www.levelextreme.com/Report.aspx?Session=5859695A6934524B6E316F3D205846334768676B78656544416E673375385234767552416272492F4E34697772

If using Views is not an option and if the structure of the result cursor changes, different result columns for example, you may need to rebuild the entire grid at runtime by re-setting all required property values, addobject'ing your member classes again, and so on.
