    just use this at the end of your button click event

    protected void btnAddButton_Click(object sender, EventArgs e)
{
   ... save data routin 
     Response.Redirect(Request.Url.AbsoluteUri);
}

    Please follow this tutorial: http://decoding.wordpress.com/2008/11/14/aspnet-how-to-call-a-server-side-method-from-client-side-javascript/

    On a sidenote: ASP.NET generates a client side javascript function that you can call from your own functions to perform the postback you want.

    -- More info on hijacking the postback event:

    You may use event handler serverclick as below

    //cmdAction is the id of HTML button as below

    <body>
    <form id="form1" runat="server">
        <button type="submit" id="cmdAction" text="Button1" runat="server">
            Button1
        </button>
    </form>
</body>

    //cs code

    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
                cmdAction.ServerClick += new EventHandler(submit_click);  
        }

        protected void submit_click(object sender, EventArgs e)
        {
            Response.Write("HTML Server Button Control");
        }
    }

    On your aspx page define the HTML Button element with the usual suspects: runat, class, title, etc.

    If this element is part of a data bound control (i.e.: grid view, etc.) you may want to use CommandName and possibly CommandArgument as attributes. Add your button's content and closing tag.

    <button id="cmdAction" 
    runat="server" onserverclick="cmdAction_Click()" 
    class="Button Styles" 
    title="Does something on the server" 
    <!-- for databound controls -->
    CommandName="cmdname"> 
    CommandArgument="args..."
    >
    <!-- content -->
    <span class="ui-icon ..."></span>
    <span class="push">Click Me</span>
</button>

    On the code behind page the element would call the handler that would be defined as the element's ID_Click event function.

    protected void cmdAction_Click(object sender, EventArgs e)
{
: do something.
}

    There are other solutions as in using custom controls, etc. Also note that I am using this live on projects in VS2K8.

    Hoping this helps. Enjoy!

    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.

    <input id="foo "runat="server" type="button" onserverclick="foo_OnClick" />

    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.

    The easiest way to accomplish this is to override the RaisePostBackEvent method. 

    <input type="button" ID="btnRaisePostBack" runat="server" onclick="raisePostBack();" ... />

    And in your JavaScript:

    raisePostBack = function(){
    __doPostBack("<%=btnRaisePostBack.ClientID%>", "");
}

    And in your code:

    protected override void RaisePostBackEvent(IPostBackEventHandler source, string eventArgument)
{
    //call the RaisePostBack event 
    base.RaisePostBackEvent(source, eventArgument);

    if (source == btnRaisePostBack)
    {
         //do some logic
    }
}
