Datagridview ComboBox Column.I am trying to get the value of the selected item in the datagridview combobox column. I set the column ValueMember and DisplayMember to a column of a database table like this :
da.Fill(ds, "Commodity");dv = ds.DefaultViewManager;Commodity.DataSource = dv;Commodity.ValueMember = "Commodity.Code";Commodity.DisplayMember = Commodity.ValueMember;
I want to show the selected item in a messagbox. Currently I have this (in a cell_leave event):MessagBox.Show(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].ValueType.ToString());This throws a "object reference not set to an instance of an object".Can someone help please?
