如何临时转换ASP.NET Ajax表单以不使用部分页面更新？

I need the ability to temporarily turn off the partial page update behavior for an ASP.NET Ajax / UpdatePanel based page. (The reason is to circumvent the issue where IE blocks "automatic file downloads" for downloads generated as a result of this postback, but I don't want to distract from my original question)

我需要能够暂时关闭基于ASP.NET Ajax / UpdatePanel的页面的部分页面更新行为。 (原因是为了避免IE阻止因自动回复而生成的下载“自动文件下载”的问题,但我不想分散我原来的问题)

I looked at the client side javascript libraries hoping to find a switch somewhere. I think a solution might involve using javascript to override the 'onclick' event handler for the control that acts as the trigger, and then calling "submit" on the form itself..

我查看了客户端javascript库,希望在某处找到一个开关。我认为一个解决方案可能涉及使用javascript覆盖作为触发器的控件的'onclick'事件处理程序,然后在表单本身上调用“submit”。

Also, using the EnablePartialRendering property on the server-side ScriptManager control won't work because that is done when the page is being built. I need to be able to do this as a result of switching a drop down list box.

此外,在服务器端ScriptManager控件上使用EnablePartialRendering属性将不起作用,因为这是在构建页面时完成的。我需要能够通过切换下拉列表框来执行此操作。

Any ideas?

Cheers!

Well, after much trial and error, I found two approaches that seemed to work:

好吧,经过多次反复试验,我发现了两种似乎有效的方法:

Use Javascript to manually submit the top level form associated with the page. This usually has the ID of "form1".

使用Javascript手动提交与页面关联的*表单。这通常具有“form1”的ID。

Create a button that is outside of any UpdatePanels and use Javascript to click the button.

创建一个位于任何UpdatePanel之外的按钮,并使用Javascript单击该按钮。

I wound up using the second approach, since it allowed me to handle the event with a specific routine without the need to guess that my postback came from a Javascript call.

我使用第二种方法结束了,因为它允许我使用特定例程处理事件,而不需要猜测我的回发来自Javascript调用。

This is an example of the code that performed the postback:

这是执行回发的代码示例:

...
if (isDownload) {
    document.getElementById('FullPostbackSubmitter').click();
    return;
}
...

Hope this helps someone else!

You can set the EnablePartialRendering property of your ScriptManager to false.
