<asp:TextBox id="Example" runat="server" />

Any help appreciated

Answer 1

Your best bet is AJAX, (or UpdatePanel in asp.net web form control, which seems to be using by you instead of MVC). This involves javascript but still it involves the server side event. Or you need to write some code overriding the TextBox event, it did involve javascript just that you don't call it explicitly on the page. Like this ASP.NET TextBox LostFocus event
