            </Columns>
        </asp:GridView>
    </ContentTemplate>
</asp:UpdatePanel>

You need to register each and every LinkButton as an AsyncPostBackTrigger.  After each row is bound in your GridView, you'll need to search for the LinkButton and register it through code as follows:

protected void OrderGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
   LinkButton lb = e.Row.FindControl("MarkAsCompleteButton") as LinkButton;
   ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(lb);
}
