  • Client-Side API


    Telerik RadToolTip provides a flexible client-side API that allows you to easily change the configuration in the browser

    1. Getting the RadToolTip client-side object:

      				var tooltip = $find("RadToolTip1");

    2. Once you get the client-side object of RadToolTip, you can use the hide, show functions to hide or show the RadToolTip. Example: 

      			    var tooltip = $find("RadToolTip1");
			    tooltip.hide();
			    tooltip.show();

    3. You can use the get_contentElement, set_contentElement functions to obtain a reference to the HTML element, holding the content of the RadToolTip or to set this element. Example: 

      			    var tooltip = $find("RadToolTip1");
			    var contentElement = tooltip.get_contentElement();
			    tooltip.set_contentElement(contentElement);
