.net - Click event on div in asp.net

Question

I have a div in default.aspx with img inside as follow

 <div id="sTab" class="tabs firsttab" runat="server">
     <asp:Image ID="sTabImg"  src="images/home.png" runat="server" />
 Activities
</div>

I want to perform some action on click of the div in ASP.NET (not in javascript).

I tried the following

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
    }

    sTabImg.Attributes["onclick"] = ClientScript.GetPostBackEventReference(this, "ClickDiv");
}

protected void ClickDiv()
{
    Label2.Text = "helo got it";
}

The page is getting refreshed and when i debugged the issue, its not entering the ClickDiv function..What wrong here..

From Here

public partial class _Default : System.Web.UI.Page, IPostBackEventHandler
{

    protected void Page_Load(object sender, EventArgs e)
    {
       div1.Attributes["onclick"]=ClientScript.GetPostBackEventReference(this,"ClickDiv");
    }

    protected void Div1_Click()
    {
      // Do something
    }

    #region IPostBackEventHandler Members

    public void RaisePostBackEvent(string eventArgument)
    {

      if (!string.IsNullOrEmpty(eventArgument))
      {

              if (eventArgument == "ClickDiv")
              {
                 Div1_Click();
              }
      }
    }

    #endregion
}

You have to implement the IPostBackEventHandler Interface.
