Here i write a Two conditions like as below

SPWeb web = SPContext.Current.Web;
SPList list = web.Lists["Student Profile"];
string caml = string.Format(@"{0}{1}", DropDownList2.Text,DropDownList3.Text);
SPQuery query = new SPQuery(list.DefaultView);
query.Query = caml;
SPListItemCollection items = list.GetItems(query);
st_attendence.DataSource = items.GetDataTable();
st_attendence.DataBind();
Controls.Add(st_attendence);
