Maybe something like this?

*-- do not define the controlsource of your grid in the form properties
*-- something like this in your listbox page1 process

>1. remove the controlsource of your grid on page 2 if it exists
>2. a record from the table is loaded into a couple of objects, to be shown on page1
>3. the cursor for the grid is zapped
>4. a bunch of records is inserted into the cursor
>5. set the controlsource of your grid on page 2 after the cursor exists




>I have a cursor I created (by select ... where .f. readwrite), and it's to be the recordsource of a grid on page2 of a pageframe. There's a listbox on page1 where a selection causes the following:

>The 2027 error appears on second or later inserts. The records to be inserted appear in separate cursors in the Data Session view. From what I saw in other threads about this error, it happens when there's a grid with a cursor like this. Now this cursor has no buffering at all, and I've moved the focus off the grid - no luck. Next thing I tried was to simply removeobject(container) from page2 whenever it deactivates, so when this happens the grid actually doesn't even exist. And I'm still getting this error.
