设置Select下拉多选框功能，赋值与绑定问题

项目需要所以更改select为多选下拉的菜单选项.

我用的是后台直接绑定

在前台aspx页面直接写一个

<div id="dropsxs" runat="server"></div>

在后台页面直接写一个绑定的方法，如果为编辑的状态时候，就传参数flage为true，否则默认设置flase就行了.

protected void Binddropcq(bool flage)
        {
            string sql = "SELECT sellertext,id FROM cyp_operate_selleragree WHERE sellertype = 2 AND deletetag = 0 ";
            DataTable dt = SqlHelper.ExecuteDataset(_cypSqlConnString, CommandType.Text, sql).Tables[0];
            //FillDll(dt, dropck);
            StringBuilder sbBuilder = new StringBuilder();
            if (dt != null)
            {
                for (int i = 0; i < dt.Rows.Count; i++)
                {
                    sbBuilder.Append("<option value='" + dt.Rows[i]["id"] + "'");
                    if (flage)
                    {
                        String[] str = chekuang.Value.Split(',');
                        foreach (string s in str)
                        {
                            if (string.Equals(dt.Rows[i]["sellertext"], s.Trim()))
                            {
                                sbBuilder.Append("selected='selected'");
                            }
                        }
                    }
                    sbBuilder.Append(">" + dt.Rows[i]["sellertext"]);
                    sbBuilder.Append("</option>");
                }
            }
            this.dropcks.InnerHtml = "<select id='dropck' multiple='multiple' name='dropck[]' runat='server' Width='544px' class='u18'>" + sbBuilder + "</select>";
        }
