Embedded CSS not working during designtime [modified]

[Fayu]

I have an embedded css resource which contains styling info for a table. When I run my app, the table is shown with the styles specified. During design time, these styles are not applied to my table. More info below. I think my problem may be that the OnPreRender may not be run during design time. What are my options? Thanks in advance. assembly.cs: [assembly: WebResource("MyNamespace.StyleSheet.css", "text/css", PerformSubstitution=true)] MyControl.cs:

    void RegisterStyleSheet()
    {
        string includeTemplate =
            "";
        string includeLocation =
              Page.ClientScript.GetWebResourceUrl(this.GetType(), "MyNamespace.StyleSheet.css");
        LiteralControl include =
              new LiteralControl(String.Format(includeTemplate, includeLocation));
        ((System.Web.UI.HtmlControls.HtmlHead)Page.Header).Controls.Add(include);
    }

    protected override void OnPreRender(EventArgs e)
    {
        RegisterStyleSheet();


        base.OnPreRender(e);
    }

Figured it out. I changd the RegisterStyleSheet to return a string:

    string RegisterStyleSheet()
    {
        string includeTemplate =
            "";
        string includeLocation =
              Page.ClientScript.GetWebResourceUrl(this.GetType(), "Fyuzon.Membership.Web.Css.BaseGridStyleSheet.css");
        return String.Format(includeTemplate, includeLocation);
    }

and override the RenderControl with the following:

    public override void RenderControl(HtmlTextWriter writer)
    {
        writer.Write(this.RegisterStyleSheet());
        base.RenderControl(writer);
    }

Works like a charm... If there is a better way of doing this, please do let me know.
