You can treat a DataGridViewComboBoxColumn or a DataGridViewComboBoxCell or a DataGridViewComboBoxEditingControl in the same way as you treat a regular ComboBox control, which means that you can either Add to its Items collection directly or you can bind data via the DataSource property and set the DisplayMember and ValueMember. If you set the properties on the column then they get automatically propagated to cells in that column and if you set them on cell then they get propagated to the editing control in that cell.

any example to fill DataGridViewComboBox from data base ? treat like a regular ComboBox is not working — shazaly, Mar 18 '15 at 22:23
