  • About this demo
  • C#
  • VB

This example demonstrates how you can automatically tooltipify Html, Server and AJAX updated Controls on your page. In order to achieve this you should set the Title property of the element if it is an HTML element or its ToolTip server property, if it is a server control to the desired tooltip text. After that you should simply put a RadToolTipManager control with an empty TargetControls collection on the page and set its AutoTooltipify property to true. The default value of this property used to be true but it is now set to false due to most common usage of the RadToolTipManager in ajax scenarios instead of for tooltipifing
