推荐答案

因为asp.net每页只允许1个表单声明我必须假设您所指的是不同的窗口，并且希望在一个窗口中选择某些内容并在另一个窗口中进行反映.

现在，最流畅的解决方案是使用javascript和一个名为lightbox的应用程序(它的窗口弹出窗口非常干净整洁.然后使用javascript根据选择进行传输.

另一个更高级的选项是使用Web服务和javascript，当在表2中选择一个对象时，它会设置一个Session变量，然后在表1中使用java-script Interval方法在该Web服务中运行一个方法，该方法将寻找该saeeion变量更改.但这要复杂得多，对于一个简单的应用程序来说可能会显得过分.

Because asp.net only allows 1 form declaration per page I have to assume you are referring to different windows and you wish to select something in one window and have it reflect in the other.

Now the sleekest solution would be to use javascript and a application called lightbox (its a kind of window popup very clean and neat. then use javascript to do the transfer based on the selection.

The other bit more advanced option would be using a web service and javascript, when an object is chosen in form 2 it sets a Session variable , then in form 1 use a java-script Interval method to run a method in the web service that will look for that saeeion variable change. but this is far more complicated and will be overkill for a simple app.
