No, not the click event. When the new row is added the defualt of the datagridcomboboxcolumn should shou the first item. I was thinking to cast the new cell which is in the [DataGridview.CurrentRow.index].cell[0] into datagridviewcomboboxcell and see if I can get the fisrt item selected, in that in the New Row added event of the Data Gridview

Hi, What I want is in the initialization. in other words when I add the datagridviewcombobox column,I want the first item to be selected. So that may have to deal of when adding a new row.
