需要在下拉菜单中同时显示PackageID和PackageName，以便客户可以选择要充值的包裹。
根据当前代码，PackageName使用DataTextFiled属性可见，该属性已在标记中设置。
请帮助同时显示PackageID和Package Name，并输入以下代码-
数据库-
CREATE TABLE [dbo].[PackageMaster](
[PackageID] [int] IDENTITY(1,1) NOT NULL,
[PackageName] [varchar](50) NULL
) ON
[PRIMARY]
Create Proc UspGetPackage
As
Begin
Select PackageID,PackageName from PackageMaster
End

private DataSet GetData(string SPName, SqlParameter SPParameter)
{
string CS = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
SqlConnection con = new SqlConnection(CS);
SqlDataAdapter da = new SqlDataAdapter(SPName, con);
da.SelectCommand.CommandType = CommandType.StoredProcedure;
if (SPParameter != null)
{
da.SelectCommand.Parameters.Add(SPParameter);
}
DataSet DS = new DataSet();
da.Fill(DS);
return DS;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DDLPackage.DataSource = GetData("UspGetPackage",null);
DDLPackage.DataBind();
ListItem lstPkg = new ListItem("--Select Package--","-1");
DDLPackage.Items.Insert(0,lstPkg);
//DDLPakcageSequence.DataSource = GetData("UspGetPkgSequence",null);
//DDLPakcageSequence.DataBind();
//ListItem pkgsequence = new ListItem("--Select Sequence--", "-1");
//DDLPakcageSequence.Items.Insert(0, pkgsequence);
}
}
在存储过程中合并两列。
Select CONCAT(PackageID,' ', PackageName ) AS PackageID_PackageName, PackageID,PackageName from PackageMaster
在.aspx中，将DataTextField="PackageName"更改为DataTextField="PackageID_PackageName"
<asp:DropDownList ID="DDLPackage" runat="server" DataTextField="PackageID_PackageName" DataValueField="PackageID"></asp:DropDownList>
