Procedure FindFromBottom
| Call: | Send FindFromBottom |
FindFromBottom is meant to be used with data-aware DataDictionary (DD)-based lists and will cause the grid to be refilled starting at the bottom of the list. You would use this when, for example, a constraint changes.
Top (FindFromTop) and Bottom (FindFromBottom) refers to the list/grid itself and not whether the list is using a regular or reversed ordering. While you could accomplish the same thing by sending a clear and a find to your list's Server DataDictionary Object (DDO), these methods are a little easier to use in that they know what index to use and they know if the ordering should be reversed.
// apply a new SQL filter and refresh the list from the top
