The RadWatermarkTextBox control represents a TextBox that shows grayed-out content when empty or not focused. This control allows you to display convenient information in TextBoxes that are not focused and contain no text. Search fields, for example, when empty or not in focus (not clicked on), can display cues to the user as to what information he or she needs to enter. Focusing/clicking on the text box removes that content. Use RadWatermarkTextBox to create user-friendly text boxes.
Style the look and feel of RadWatermarkTextBox by using any of the 10+ built-in professionally designed themes that come with UI for Silverlight. Themes include the new Office 2013 theme, Windows8 and Windows8Touch themes as well as many others.
