[英]ASP.NET form with two concurrent postbacks
I have an ASP.NET web form with two dropdown lists having autopostback.我有一个 ASP.NET web 表单,其中包含两个具有自动回发功能的下拉列表。
When I change the selected item in the first dropdown the page postback.当我在第一个下拉列表中更改所选项目时,页面回发。 But since the page has much work to do on server side, then it takes time to load again in the browser.
但是由于页面在服务器端有很多工作要做,所以在浏览器中再次加载需要时间。
At the time where the form is in processing in the server, if I change the selected item in the second dropdown then the behaviour is not the same always.在服务器中处理表单时,如果我在第二个下拉列表中更改所选项目,那么行为总是不一样的。 Some times it submits the form again, some time it doesn't.
有时它会再次提交表单,有时则不会。
How to have it postback even if the page is not loaded completly in the browser?即使页面没有在浏览器中完全加载,如何让它回发?
