Error repopulating MSHFlexGrid

I have a form to allow users to select historical data from a table by any of several criteria using combo boxes. The grid loads fine at Form load, but when the selections are made, and I try to load it again with the recordset from the selection statement, I get the following error:

Run-time error '30023':
Unable to access data. DataSource settings may be incorrect, or the DataSource functionality may be limited.

I have tried declaring this recordset locally, and in the General section.  I am clearing the grid, before opening the recordset and before setting the DataSource value to the recordset.  I have verified that, when I reach the statement assigning the DataSource for the grid, that my sql SELECT statement is correct, that my recordset is open, and has the selected data.

Have you tried putting a data control on your form and connecting your grid to the data control? Then you could try refreshing the data control.

I'm not even sure if this is possible. Just an idea...

Thank you for the suggestion.  Actually though, we have a company policy against using data controls. We try to stick to ADO objects.

From what I've seen by looking around, it seems a lot of people have had this problem.

Try setting

MSHFlexGrid1.DataSource = Nothing

before you reset it.

Yes, thanks again, but I had actually seen that suggestion in previously asked questions before I posted this one.  I have tried that, before setting the datasource, I've tried it earlier on, before opening the recordset.  No difference.  In debugging the code though, even without trying to assign Nothing as the datasource, I can see that that is the value of the datasource property right before I execute the datasource assignment line that causes the error.

I have seen a situation where checking the recordset for eof prior to the set grd.datasource = recordset caused problems.  

I did try this at home last night on my system and I had no problem. Here at work, I have the same problem.

Excellent.  I was in fact testing for .EOF before the datasource assignment.  I have now tried closing the recordset after the .EOF test, and then reopening the recordset, and that has eliminated the error.  Thanks for the help.
