I've successfully subclassed an ASPxTextBox to work with StrataFrame using the following code ... it works quite well.  The only problem I'm having is this, what code do I have to add in order to get that red arrow to appear next to it when a broken rule has been added for the field associated with it.  See attached:

Ben nailed it ... here is the solution:

    protected override void Render(System.Web.UI.HtmlTextWriter writer) {
        
base.Render(writer);
        if 
(_InError) {
            writer.Write(BrokenRuleRenderer.RenderBrokenRule(
this));
            
writer.Flush();
        
}
    }
