blocks|key|1025503|text|这可能有点夸张，但您可以设置一个javascript计时器来触发web服务调用。.NET+web服务可以接受表单数据并保存它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1025504|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This may be overkill, but you could setup a javascript timer to fire a web service call. The .NET web service can accept the form data and save it.

blocks|key|1020516|text|难道你不能使用javascript计时器来“点击”提交按钮吗？听起来使用这个表单真的很烦人，如果当你试图填写它的时候，它一直在回复。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1020517|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Couldn't you use a javascript timer to "click" the submit button? It sounds like using this form would be really annoying though, if it keeps posting back while you're trying to fill it out.

No great solutions so I build my own. A pretty simple custom control. Comments welcome.

blocks|key|3533452|text|使用javascript调用__doPostBack("clientIdOfSubmitButton",+null)。这将触发一个回发，就像该按钮(或您想要的任何其他控件)触发了它一样。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3533453|entityMap^0|E|18|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

with javascript, call <code>__doPostBack("clientIdOfSubmitButton", null)</code>. This will fire off a postback just as if that button (or any other control you want) had triggered it.

I have your basic asp.net web form which contains some client-side JavaScript that forces the page to time out and then redirect after 5 minutes. Mainly to protect possibly sensitive information.

At timeout, I want to force a server post back allowing me to save the form values for future edits.

I have played with both ClientScript.GetPostBackClientHyperlink() and ClientScript.GetPostBackEventReference(). Both seem to cause EventValidation issues for me. Yes, I can turn off Event Validation but is there a different or better workaournd?

Ideally, I don’t want to invoke a control (which has to be displayed) but just cause a postback with some type of argument that I can recognize serverside as being the result of a timeout condition.
