Question

How can i use HTML button like an ASP.NET Button?

Answer 1

Html tags attributed with runat="server" are called HtmlControls and you need to handle ServerClick event.

Markup

<button id="button1" runat="server" onserverclick="doIt" >Submit</button>

Code behind

protected void doIt(object sender, EventArgs e)
 {
   Response.Write("Hello World!!!");
 }
