You must detach the grid from the BindingSource before changing the BindingSource.DataSource property. Then you can attach the BindingSource to the grid. However, the best solution would be to create a new BindingSource instance for your new data source.
Thank you
But why did it work in release 3.2.2?
There were problems with adding records to the grid's data source. We've fixed them, but now there is the described limitation of changing the BindingSource.DataSource on-the-fly.
Thank you
