使用组合框更新另一个组合框中的内容。 [英] Using a combobox to update the content in another combobox.

问题描述

过去4天我一直在试图让组合框工作。我正在尝试将现有的客户端应用程序转换为Web，并且客户端应用程序的一个功能是使用组合框来允许它们输入不在系统中的数据。但是，如果他们选择或输入现有数据，那么系统将使用一组与初始数据相关的相关数据填充另一个组合框。由于aspx没有组合框，必须使用jquery。试图做回发有很多问题。管理进行回发但似乎无法将信息填充到其他组合框中。有人可以帮忙吗？请！

I have been cracking my head for the last 4 days trying to get the comboboxes to work. I'm trying to convert an existing client app into web and one of the feature of the client app is having a combobox to allow them to enter data that are not in the system. But if they select or entered an existing data then the system would populate another combobox with a set of relevent data pertaining to the initial data. As aspx does not have combobox, has to use jquery. Having lots of problem trying to do the postback. Managed to do the postback but doesn't seems to be able to get the info populated to the other combobox. Can someone help? Please!
