asp.net control (.ascx) with dijit?

i've tried to get an asp.net dropdownlist control to become a dijit combobox but it's not working.

i've tried this:

<asp:DropDownList ID="ddlUserID" dojoType="dijit.form.ComboBox" runat="server" 
    DataTextField="FullNameAndUserName"
    CssClass="stdtext" DataValueField="UserID" AppendDataBoundItems="Tru开发者_运维百科e" 
    AutoPostBack="True"
    meta:resourcekey="ddlUserIDResource1" EnableTheming="False">
    <asp:ListItem Text="(All Users)" Value="0" meta:resourcekey="ListItemResource1" />
</asp:DropDownList> 
   <script type="text/javascript" src="../scripts/dojo/dojo.js"></script> 
   <script type="text/javascript">
    dojo.require('dijit.form.ComboBox');
</script>

the path to dojo.js is relative to the containing parent page of the ascx control and loads fine according to firebug.

the rendered html is this:

   <select id="invoiceReport1_ddlUserID" class="stdtext" dojotype="dijit.form.ComboBox" onchange="javascript:setTimeout('__doPostBack(\'invoiceReport1$ddlUserID\',\'\')', 0)" name="invoiceReport1$ddlUserID">
   </select>
   <script src="../scripts/dojo/dojo.js" type="text/javascript">
   </script>
   <script type="text/javascript">
   </script>
   <script type="text/javascript">

looking at the examples from http://docs.dojocampus.org/dijit/form/ComboBox i cant see why the resulting select tag is not a combobox.

i've also tried this:

HtmlGenericControl ctrl1 = new HtmlGenericControl("Script");
ctrl1.Attributes.Add("Type", "Text/Javascript");
ctrl1.Attributes.Add("src", "../Scripts/dojo/dojo.js");
this.Page.Header.Controls.Add(ctrl1);


HtmlGenericControl ctrl2 = new HtmlGenericControl("Script");
ctrl2.Attributes.Add("Type", "Text/Javascript");
ctrl2.InnerText = "dojo.require('dijit.form.ComboBox');";
this.Page.Header.Controls.Add(ctrl2);

Any suggestions?

the solution ended up being this:

you must refer to dijit.css either in your stylesheet or directly.
