CombBox 绑定数据

1.给需要绑定的数据加入新行

DataSet dsFundCompany;

DataTable dt = dsFundCompany.Tables[0];    DataRow dr = dt.NewRow();    dr["iCode"] = "-1";    dr["CName"] = "全部基金公司";    dt.Rows.InsertAt(dr, 0);//加入到第一行，dt.Rows.Add(dr)--加到最后;    combCompany.DataSource = dt;

    combCompany.DisplayMember = "CName";    combCompany.ValueMember = "iCode";        combCompany.SelectedValue = dsFundCompany.Tables[0].Rows[0]["icode"];
