如何使用AutoPostBack在ModalPopUpExtender中使用2下拉列表 [英] How to use 2 dropdownlist in ModalPopUpExtender using AutoPostBack

问题描述

大家好，



我使用的是ModalPopupExtender，在Panel中，我有2个下拉列表。

选择网络：< asp：DropDownList ID =ddlNetworkwidth =150pxrunat =serverAutoPostBack =trueOnSelectedIndexChanged =ddlNetwork_SelectedIndexChanged>



选择人物：< asp：DropDownList ID =ddlPeoplewidth =150pxrunat =server>



ddlPeople的加载取决于ddlNetwork的选择，但由于它的ModalPopupExtender，页面被加载。并且在ddlNetwork中不使用AutopostBack =true时，ddlPeople中的值将无法加载..



如何使用此????

解决方案

如果您正在使用ModalPopupExtender，那么级联下拉可能是一种前进的方式，因为您首先使用的是ajaxcrontroltookit？

Hi all ,

I am using a ModalPopupExtender and in Panel, I've 2 dropdownlist.
Select Network : <asp:DropDownList ID="ddlNetwork" width="150px" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlNetwork_SelectedIndexChanged">

Select People : <asp:DropDownList ID="ddlPeople" width="150px" runat="server" >

ddlPeople is loaded depending on selection of ddlNetwork but since its a ModalPopupExtender, the page gets loaded. And without using AutopostBack="true" in ddlNetwork the values in ddlPeople will not get loaded..

How to use this ????

解决方案

If you're using the ModalPopupExtender, perhaps the cascadingdropdown would be a way forward, since you're using ajaxcrontroltookit in the first place?
