Major Datagrid Issues

[zryip theSlug]

Hi Pete,

Sorry for the delay in the answer, I've just read your post.


Have you tried to send a ResetControl command to the datagrid, before
to change the dgNumberOfRecords property?

Example:

command PopulateMyDataGrid
   doMySQLStuff

   send "ResetControl" to grp "myDataGrid"
   set the dgNumberOfRecords of grp "myDataGrid" to tNumberOfRecords

end PopulateMyDataGrid
