c# asp.net Form with a submit button and a button that executes a command?
提问by JazziJeff
basically i have a form with the runat server tag. within this form i have an asp repeater and asubmit button- but i also want to have a button which will call a c# method in my code - can someone please give me an idea as to how to go about this? Also in this code the selectindexchanged event does not fire even though its autopostback value is true which is weird :/
基本上我有一个带有 runat 服务器标签的表单。在这个表单中，我有一个 asp 中继器和一个提交按钮——但我也想要一个按钮，它会在我的代码中调用 ac# 方法——有人可以告诉我如何去做吗？同样在此代码中，即使其 autopostback 值为 true，selectindexchanged 事件也不会触发，这很奇怪：/
thanks
谢谢
EditOK solution seems to be remove the action tab and i have then set the property through some JavaScript instead :) why cant things be straightforward
编辑OK 解决方案似乎是删除操作选项卡，然后我通过一些 JavaScript 设置了属性:) 为什么事情不能直截了当

In the dropdownlist property, you can set AutoPostBack = true. With this it will send the post back to server therefore event can be triggered.
在下拉列表属性中，您可以设置 AutoPostBack = true。有了这个，它会将帖子发送回服务器，因此可以触发事件。
oh. sry i didn't see you already have it
