       The TextBox's backcolor is the same no matter it's in editor state or readonly state, and i can't tell it's state from it's appreance.
    I want it's backcolor changes when it turns to readonly state. Is there any easy way to do this?

    Looking forward to your replay.

    Hi zeng dongmei,

    The easiest approach for your scenario is to use an extended RadTextBox:
    public class MyTextBox : RadTextBox
        protected override void OnReadOnlyChanged(EventArgs e)
            if (this.ReadOnly)
        private void SetColor(Color color)
            this.TextBoxElement.BackColor = color;
            this.TextBoxElement.Fill.BackColor = color;
            this.TextBoxElement.Border.ForeColor = color;
        public override string ThemeClassName
                return typeof(RadTextBox).FullName;

    Best wishes,
    the Telerik team
