So it sounds like you want to populate your ComboBox with all the distinct values from a column.

Look for the event "CellValueChanged" in the DataGridView. This should fire after the cell's value has been edited, and focus has left the cell (so like leaving edit more).

However, I would suggest, that when they leave editing, you get all the distinct values from a column, that way in case they changed one that's no longer present, it's not in the ComboBox. Just google something like "Select Distinct Values Datagridview column" or something like that (make sure you clear the ComboBox first if you do this)

i tried to clear combo box but still not clear combo box
like .. combobox1.items.clear();
oR
combobox1.clear();
but not working

should be comboBox1.Items.Clear(); That should remove all items in the ComboBox (if that is not working make you are executing it on the correct ComboBox and don't have some code trying to repopulate it before you desire).
