NullText
RadTextBoxControl has a NullText property that is not shared by the standard Windows Forms text box. This property specifies what text to be displayed when the control has no Text value. By default, when the control receives focus, this text is automatically removed. This behavior can be controlled by the ShowNullText property. If it is set to true the NullText will be shown even when the text box is focused until you enter some text in the editor.
