You can't find the dropdown selected value like this. You need to find the control first using FindControl method:-

DropDownList DropDownList2 =  (DropDownList)gridview1.Rows[0].Cells[0]
                                                     .FindControl("DropDownList2");
string str = DropDownList2.SelectedValue;
