Answer 1

在ButtonLogin_OnClick里面做

this.ButtonLogin.Attributes.Add("dojotype", "dijit.form.Button");

Answer 2

You can do it by JQUERY. I'm adding attribute to "a" tag:

     <a href="#" id="btnAttrib">Add Attrib</a>
     <script type="text/javascript">
            $("#btnAttrib").click(function () {
                $("#btnAttrib").attr("rel", "nofollow");                  
             })
     </script>

I think you change it to:

     <button id="ButtonLogin" runat="server" onServerClick="ButtonLogin_OnClick" jsid="ButtonLogin" style="float: right;padding: 5px 15px 0px 0px;">Login</button>

     <script type="text/javascript">
            $("#ButtonLogin").click(function () {
                $("#ButtonLogin").attr("dojotype", "dijit.form.Button");                  
             })
     </script>
