I have a component that determines a value on a postback event. protected void Button_Click(object s, EventArgs e) { HiddenField.Value = 5; } There's more involved in the value of course, but HiddenField is an asp:HiddenField control with runat=server set. I have in my javascript: var id = $("#<%= HiddenField.ClientID %>").val();...
One of our ASP.NET WebForms 3.5 pages just suddenly decided not to render the __doPostBack() javascript method, along with the supporting <hidden> fields, anymore. Everything else seems OK on the page - the only thing I changed was that I removed a postback handler on a SelectList control, and changed AutoPostback from True to False on ...

Hey all. I've tried to Google and research this, but without luck. I am curious to know how "modern" web-apps/sites do postbacks, meaning when they are sending back user-input to the site be processed.

In order to avoid having extra code on the page load...

I have a LinkButton that I need to perform a click on to cause a postback. The actual link target is: javascript:__doPostBack('ctl00$c1$btnRefreshGrid',''); Clicking the link does perform the postback, as verified by a breakpoint in the code-behind. Also pasting javascript:__doPostBack('ctl00$c1$btnRefreshGrid','') in the address bar o...

I am researching web frameworks that are in common usage. In ASP.NET there is the notion of a "postback". Specifically, the framework automatically adds a hidden FORM to each page which can be submitted by JavaScript with various state parameters, etc. The "action" URL for this form is always the current page's URL, including its quer...
