How to call C# method from standard HTML input

Question

Ok, so I've got some HTML that's generated dynamically. Part of it

StringBuilder.Append("<input type=\"button\" onclick=\"Email_Clicked\" value=\"Email\" class=\"button\" runat=\"server\" />");

I need this to call C# method Email_Clicked

How can I accomplish this without asp:button control?

@Stuart Dunkeld - That question is similar, but this is not an exact dup. I dont care if the solution is AJAX, as long as it works. — P.Brian.Mackey, Mar 29 '11 at 14:45

What about doing an ajax call to a method in your aspx page with jQuery? Take a look at this post about Using jQuery to directly call ASP.NET AJAX page methods

As mentioned before, Ajax is easy to implement and will do the trick. Put this attribute on your method:

<Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.ReadWrite)> _
        Public Function DoSomething() As Integer
            'handle stuff
        End Function

you can call the method from javascript by using this:

Declaration.DoSomething()

don't forget to register your ajax call object in for example the pageload:

Ajax.Utility.RegisterTypeForAjax(GetType(Declaration))

If you don't register it, calling Declaration.DoSomething() won't work.

This looks like a good solution. Is the "Ajax.AjaxMethod()" assembly available as a seperate download somewhere? – P.Brian.Mackey Mar 29 '11 at 15:02
i'm not sure where my company got it, but i thought you could download it, like discussed in this post: http://forums.asp.net/t/1383384.aspx – Terry Mar 29 '11 at 15:12

You can't.. directly.

You can use Page Methods or plain AJAX for this though.

Here is relevant question here combining both:

You can "manually" force a postback by calling the __doPostBack method in JavaScript. The following web page contains a short tutorial on how to do that:

I tried this before I posted on SO. I could not get it to call the method, never hit breakpoint. – P.Brian.Mackey Mar 29 '11 at 14:50
