将多个值绑定到ASP.NET中DropDownList的DataTextField [英] Bind Multiple Values to DataTextField of DropDownList in ASP.NET

问题描述

var query = (from Customer in context.tbl_Customer

                            select new
                            {
                                Value = Customer.CustomerID,
                                Text = Customer.CName
                            });
               return query;

以上查询返回值和文字

Above query returns value and text

public static void FillDDLCustomer(DropDownList ddl, Boolean is_Select, Boolean is_All)
       {
           try
           {
               ddl.DataSource = _ComboRepo.FillDDLCustomer();
               ddl.DataValueField = "Value";
               ddl.DataTextField = "Text"; //Here I wanna bind Text as well as Value
               ddl.DataBind();
               if (is_Select)
               {
                   ddl.Items.Insert(0, new ListItem("------Select------", "0"));
               }
               else
               {
                   ddl.Items.Insert(0, new ListItem("------Select All------", "0"));
               }
           }
           catch (Exception ex) { }
       }

                                Text=string.Format("{0} {1}" ,Customer.CustomerID,Customer.CName)
