This article demonstrates how to enable and use the WAI-ARIA support of the RadToolTip and RadToolTipManager controls.
The WAI-ARIA Suite defines an approach to make web content and web applications more accessible to people with disabilities. RadToolTip and RadToolTipManager offer WAI-ARIA support.
In order to enable the WAI-ARIA support, set the RadToolTip / RadToolTipManager contol's EnableAriaSupport property to true as shown in the example below.
Example 1: Setting the EnalbeAriaSupport property for RadToolTip and RadToolTipManager.
<telerik:RadToolTip RenderMode="Lightweight" EnableAriaSupport="true" runat="server" ID="RadToolTip1"></telerik:RadToolTip> <telerik:RadToolTipManager RenderMode="Lightweight" EnableAriaSupport="true" runat="server" ID="RadToolTipManager1"></telerik:RadToolTipManager>
RadToolTip1.EnableAriaSupport = true; RadToolTipManager.EnableAriaSupport = true;
RadToolTip1.EnableAriaSupport = True RadToolTipManager1.EnableAriaSupport = True
According to the WAI-ARIA specifications, the first input in a dialog should get the focus when the dialog opens. We have no control over the content, so this should be done by the developer. The OnClientShow event and the Client-side API of the control can be used for this.
RadToolTips created by a RadToolTipManager will inherit the value of its EnableAriaSupport property.
