Removing grid column not update grid display

[Administrator]

I have a griddataboundgrid that originally contains 3 columns. Depending on user selection in a combobox in the form, a column can be removed. But, after the column removal, I still see 3 columns, but the last column is blank, but still selectable by mouse. When checking for GridBoundColumns.Count, it says 2. What I did is use GridBoundColumns.Remove(column) to remove the column. What could be wrong? I have attached the screenshot. Thanks very much.

After removing the gridbound column, try calling grid.Binder.InitializeColumns and then grid.Refresh to see if this handles this problem.
