calling server side event from html button control

Question

I am creating an application using ASP.Net, in which I have a HTML button on an aspx page.

Answer 1

If you are OK with converting the input button to a server side control by specifying runat="server", and you are using asp.net, an option could be using the HtmlButton.OnServerClick property.

This should work and call foo_OnClick in your server side code. Also notice that based on Microsoft documentation linked above, you should also be able to use the HTML 4.0 tag.
