RadWindow Structure
RadWindow controls contain a title bar, which displays the icon, title, and title bar buttons, a content window, and a status bar. These are all configurable using the properties of RadWindow.
Title Bar: Use the VisibleTitlebar property to control whether the window has a title bar.
Icon: Use the IconUrl property to specify the image that appears at the far left of the Title Bar.
Title: By default, the Title shows the title of the HTML in the Content Window or theURL that provides that content. You can override this behavior by setting the Title property.
Title Bar Buttons: Use the Behaviors property to determine which of the buttons that let the user pin, reload, minimize, maximize, restore, and close the window appear on the Title Bar.
Content Window: Use the NavigateUrl property to control what content appears in the Content Window.
Status Bar: Use the VisibleStatusbar property to control whether the window has a Status Bar to display information about the status or contents of the Content Window.
