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();
}
}
