OnServerClick上的锚标记未触发

Question

I have 3 tabs, On which I want to show the respective data. I have given a attribute as onserverclick to the anchor tag inside <li> . but the problem is that it is not firing.

Also When I tried putting a breakpoint it was not working. Here is my piece of html code:-

<ul class='tabs1'>
            <li><a href='#tab1' id="allNews" runat="server" onserverclick="allNews_ServerClick">All News</a></li>

            <li><a href='#tab2' id="forNgo" runat="server" onserverclick="forNgo_ServerClick">For NGO</a></li>
            <li><a href='#tab3' id="fromNgo" runat="server" onserverclick="fromNgo_ServerClick">From NGO</a></li>
        </ul>

Please suggest what might be the issue which is preventing to work.

UPDATE

Server code:-

protected void fromNgo_ServerClick(object sender, EventArgs e)
    {   
        using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString))
        {   
            string query = "SSELECT dbo.tbl_post.title, dbo.tbl_post.description, dbo.tbl_post.active, dbo.tbl_post.dateforPost, dbo.tbl_ngoname.ngo_name, dbo.tbl_User.usertype FROM dbo.tbl_post INNER JOIN dbo.tbl_User ON dbo.tbl_post.UserId = dbo.tbl_User.Id INNER JOIN dbo.tbl_ngoname ON dbo.tbl_post.NgoId = dbo.tbl_ngoname.Id AND dbo.tbl_User.NgoId = dbo.tbl_ngoname.Id WHERE (dbo.tbl_User.usertype=2)";
            SqlDataAdapter sda = new SqlDataAdapter(query, conn);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            lstNews.DataSource = dt;
            lstNews.DataBind();
        }
    }

protected void Tab1Function()
    {   
        using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString))
        {   
            string query = "SELECT dbo.tbl_post.title, dbo.tbl_post.description, dbo.tbl_post.active, dbo.tbl_post.dateforPost, dbo.tbl_ngoname.ngo_name, dbo.tbl_User.usertype FROM dbo.tbl_post INNER JOIN dbo.tbl_User ON dbo.tbl_post.UserId = dbo.tbl_User.Id INNER JOIN dbo.tbl_ngoname ON dbo.tbl_post.NgoId = dbo.tbl_ngoname.Id AND dbo.tbl_User.NgoId = dbo.tbl_ngoname.Id WHERE (dbo.tbl_User.usertype=2)";
            SqlDataAdapter sda = new SqlDataAdapter(query, conn);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            lstNews.DataSource = dt;
            lstNews.DataBind();
        }
    }

And then, use this in your PageLoad

    If (!IsPostBack)
     {
       Tab1Function();
     }

Something like that.

EDIT: I think your tabs are not working. So lets direct you to the TabContainer then.

<ajaxToolkit:TabContainer ID="Tab_Container" runat="server" ActiveTabIndex="0" CssClass="CustomTabStyle" EnableTheming="False" ScrollBars="Both" Style="vertical-align: top" Width="900px">
 <ajaxToolkit:TabPanel ID="TabPanel_1" runat="server" HeaderText="TabPanel1" ScrollBars="Both">
 <HeaderTemplate> All News </HeaderTemplate>
   <ContentTemplate>
//Your Table/Datagrid containing your data here.. Whatever you are binding your data to.
 <table><tr><td></td></tr></table>

 </ContentTemplate>
                                    </ajaxToolkit:TabPanel>
                                    <ajaxToolkit:TabPanel ID="TabPanel_2" runat="server" HeaderText="TabPanel3">
                                        <HeaderTemplate>
                                            For NGO
                                        </HeaderTemplate>
                                        <ContentTemplate>
 <table><tr><td></td></tr></table>
</ContentTemplate></ajaxToolkit:TabPanel></ajaxToolkit:TabContainer>

I hope that makes sense.

You need to create the Click event for Anchor tag in page load as below

private void Page_Load(object sender, System.EventArgs e)
{
HtmlAnchor HA = new HtmlAnchor();
HA.ServerClick += new EventHandler(linkclickeve1);
HtmlAnchor HA2 = new HtmlAnchor();
HA2.ServerClick += new EventHandler(linkclickeve2);
}

protected void linkclickeve1(object sender, System.EventArgs e)
{

}

protected void linkclickeve2(object sender, System.EventArgs e)
{

}
