    I am upgrading from an old solution, see, since this version is missing some functionality which I now need.

    My class inherits from RadTextBox where I override CreateChildItems and create my own.

    I follow the logic from your source and it all works perfectly. Except the multiline property, how can I implement it?

    I use the following controls.
            private readonly RadTextBoxItem textBox = new RadTextBoxItem();
            private readonly TextPrimitive title = new TextPrimitive();
            private readonly TextPrimitive validation = new TextPrimitive();

    A cut down version of CreateChildItems

                BoxLayout layoutTexts = new BoxLayout();
                layoutTexts.Orientation = Orientation.Horizontal;
                layoutTexts.StretchVertically = false;  // when true the control is drawn differently


                BoxLayout layout = new BoxLayout();
                layout.Orientation = Orientation.Vertical;





                Size = new Size(425, 34); // default size

    Hi Jorge Delgado-Lopez,

    Thank for writing.

    You should set the Control's AutoSize property to false
      public LabelMultilineTextBox() 
           this.AutoSize = false

    Also, override InitializeRootElement and set the RootElement's Stretch Property to True
     protected override void InitializeRootElement(RootRadElement rootElement) 
           rootElement.StretchVertically = true;            

    Please refer the attached project.
