    Is it at all possible to change the style of the RadTextBox when there is no text value - i.e Null Text?

    I am used to the Infragistics controls and there is a nice and easy appearance for this.

    Hello Andez,

    Thank you for writing.

    Yes you can style the null text. For example you can change its color as follows:
    radTextBox1.TextBoxElement.TextBoxItem.NullTextColor = Color.Red;

    Additionally you can use the GotFocus and LostFocus events to change other styles:
    void radTextBox1_GotFocus(object sender, EventArgs e)
        if (radTextBox1.Text == null || radTextBox1.Text == string.Empty)
            this.radTextBox1.TextBoxElement.BackColor = Color.White;
    void radTextBox1_LostFocus(object sender, EventArgs e)
        if (radTextBox1.Text == null || radTextBox1.Text == string.Empty)
            this.radTextBox1.TextBoxElement.BackColor = Color.LightGray;

    Please let me know if there is something else I can help you with.
