Hi, if a combobox column is filtered and i change in the result rows any combobox-entry and leave the row with cursor-up an exception occours. Your sendet sample in the attachement has the same behavior. Will these bug in GridSuite Version 2.0 resolved? thanks markus

If you are not using the derived filterbar that tries to handle the foreign key combobox mapping, then things should work. There was a problem in, but this problem has been fixed in the latest private build. You can get this build by submitting a Direct Trac support incident and requesting it. Do you see the problem in our Filterbar sample, or is it only when you use teh derived filterbar?
