如何在用户控件中访问子控件的HtmlControl.Style？

Question

I have a user control that contains the following text (among other things) in the .ascx file:

<div id="divLine" runat="server">
    <-- Stuff -->
</div>

In the C# code, I have this property:

[Browsable(false)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public CssStyleCollection LeftStyle
{
    get { return divLeft.Style; }
}

This is pretty much copied from System.Web.UI.HtmlControls.HtmlControl.cs . However, when trying to use my custom control in .aspx pages, I can't seem to access <uwc:UserControl LeftStyle="stuff"> like I could access it directly in <div style="stuff"> . Is there any way to?

No answer, so I took a different approach. divLine only contained an asp.net Label , which I exposed as a public property of the control. Apparently you can do things like <asp:Label runat="server" style="stuff"/> . Intellisense will not indicate that style is a valid attribute, but it can still be used. Just like other asp.net controls, attributes the IDE doesn't recognize will still be written to HTML. Heck, once you get style=" written, you'll even get the typical drop-down guide for it.
