Use a PostBackTrigger to perform exclusion rather than having to specify a large number of includes.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    <asp:LinkButton ID="lnkExport" runat="server" OnClick="lnkExport_Click" Text="Export Data"></asp:LinkButton>
    </ContentTemplate>
    <Triggers>
          <asp:PostBackTrigger ControlID="lnkExport" />
    </Triggers>
</asp:UpdatePanel>

Set UpdateMode=Conditional and provide exclusive Triggers for the UpdatePanel.

you must add some controls in code behind and in the right event and register it for exclusion(postback) instead and AsyncPostBack which is a ajax call.

ScriptManager.GetCurrent(this).RegisterPostBackControl(btnAdd);

https://stackoverflow.com/a/23036830/184572

protected void grdExpense_RowCreated(object sender, GridViewRowEventArgs e)
    {
        LinkButton btnAdd = (LinkButton)e.Row.Cells[0].FindControl("btnAdd");
        if (btnAdd != null)
        {
            ScriptManager.GetCurrent(this).RegisterPostBackControl(btnAdd);
        }

    }

look for another similar page which excludes all the controls in a gridview

http://www.aspsnippets.com/Articles/Assign-PostBack-Trigger-Full-PostBack-for-LinkButton-inside-GridView-within-AJAX-UpdatePanel-in-ASPNet.aspx

private void RegisterPostBackControl()
{
    foreach (GridViewRow row in GridView1.Rows)
    {
        LinkButton lnkFull = row.FindControl("lnkFull") as LinkButton;
        ScriptManager.GetCurrent(this).RegisterPostBackControl(lnkFull);
    }
}
