Take Two DropDownList&在Asp.Net C＃中获取公共数据 [英] Take Two DropDownList & Fetch Common Data In Asp.Net C#

问题描述

嗨..



i希望从sql server的一个下拉列表中获取数据

&other dropdownlist无法显示我们选择的ddl1。



假设我们有一个table.it应该进入下拉列表-1

id-1,2,3,4

来源 - 浦那，孟买，德里，加尔各答



和第二个包含目的地&它还使用普通表





所以我们如何才能实现这一目标

来源 - 浦那

目的地可能是 - -Mumbai，Delhi，Kolkata
