Add a custom ResetGrid() method to the grid class to populate the cursor by ZAPping it, SELECTing the appropriate records into a temporary cursor and then appending the records from the temporary cursor into the one defined as the grid's RecordSource.

Hmmm, it seems like a LOT OF WORK, I don't want to recreate the Grid after an Zapping or Packing, actually I don't use those issue, generally I use Views or RecordSourceType=4. I just want to use it for internal process. Thank you anyway.

>One way to avoid having the grid turn into a blank grey blob is to set its RecordSource to an empty string before running the SELECT and then resetting it afterward. Although this will work in the simplest of cases, it is not a solution we recommend. While it will keep your grid from losing its mind, the grid's columns still lose their ControlSources and any embedded controls. So, this works if your grid uses base class headers, base class text boxes, and displays the fields from the cursor in exactly the same order as they are SELECTed. Otherwise, you have to write a lot more code to restore all the things that get lost when the grid is re-initialized.
