填充数据表中的数据.然后将此数据表保留到DropDownList.

Fill the the data''s in DataTable. Then assisgn this DataTable to the DropDownList.

ddl.DataSource = dataTable
ddl.DataValueField = "value field name"
ddl.DataTextField = "textfield name"
dd.DataBind()

OleDbConnection con = new OleDbConnection(connection);
                DataSet ds = new DataSet();
                OleDbDataAdapter ad = new OleDbDataAdapter("select Tittle from smsstorage order by Tittle Asc", con);
                ad.Fill(ds);
                //ddlsmsstorage.Items.Clear();
                ddlsmsstorage.Items.Add("---Select---");


                for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                {
                    ddlsmsstorage.Items.Add(ds.Tables[0].Rows[i][0].ToString());

               
                   
                }
