Hi islam 2, welcome here.
You first have to do a DataGridView1.Rows.Add();

thanks alot mr.ddanbe...

what if i want make cell be a combo box represent the quantity ana another cell is calculated cell of ( quantity*cost )

This is a code snippet I posted here some time ago you can bring into use for your case. Because you fill your cells with values from Textboxes why not use the value of a combobox to fill such cell.
Do you only have specific quantity values?
