I receive an "Operation did not succeed because the program cannot commit or quit a cell value change" error when I change the DataSource of the BindingSource bound to the DataGridView. This occurs even if I clear the BindingSource (no errors and there are no rows in the DataGridView) and then assign the new DataSource.
mUtilizations= New Utilizations()
CU_BindingSource.DataSource = mUtilizations
The cell value must be getting assigned but not committed and then reassigned, but I cannot figure out where. The data displays correctly, although if there were more rows with the initial data the extra rows remain as blank row.
Here is the trace:
Message=Operation did not succeed because the program cannot commit or quit a cell value change.Source=System.Windows.Forms
