Question

If I have a method that returns a datagridview and the flow is similar to this:

if (ds.Tables.Count == 0)
        {
            SharedMethods.updateStatus("There are no excluded results to display");
            //return dgv;
        }
        else
        {
            dgv.DataSource = ds.Tables[0];
            dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
            dgv.AllowUserToAddRows = false;

            return dgv;
        }

If the if condition is true then I do not want to return a datagridview(as there is no data), what can I return in this case? If I return null, then the calling method has a null datagridview that causes later problems.

Thanks.

Just set the grid’s Visible property to false if you have nothing to show.
