如何知道document.forms ['aspnetForm']。submit（）在服务器端进行提交？

Question

I use

document.forms['aspnetForm'].submit() 

to submit the form. There are other buttons doing some other things at the server side too.

Is it possible at the server side, eg, in Page_Load(object sender, EventArgs e), use some method to check client side called this

document.forms['aspnetForm'].submit() 

?

thanks

================more explain===================

for example, clicking either button below will submit the form to server side, how do I know which one is clicked in Page_Load?

<input type="button" value="Submit" onclick="document.forms['aspnetForm'].submit()" />
<input type="submit" value="Edit" />

You can set a value in a hidden field at the same time you call the .submit() in your JavaScript. Like:

<input type="hidden" id="client-submit" value="true" />

(Then check for that form-field value on the server-side.)
