How does callback work in telerik web ui?


Asked by Ryder Rice on Nov 30, 2021 Web Services



The callback functionality and the OnCallbackUpdate are available and work both for simple and rich content. In the case of simple content, you can directly change the Text and ContentIcon property in the callback without using AJAX to update the notification.
Accordingly,
If you want to add Telerik controls for .NET 3.5 or .NET 4.0 web project you should select the Telerik.Web.UI.dll from the C:\Program Files (x86)\Progress\UI for ASP.NET AJAX RX YYYY\Bin35 or ~/Bin40 folder. If the controls do not appear in the ToolBox, please make sure that the project is of type ASP.NET Web Forms site or application.
Also, The AjaxPanel is part of Telerik UI for ASP.NET AJAX, a professional grade UI library with 120+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial. Ajax-enables all controls inside that normally work with postbacks.
Besides,
Using Telerik UI, we were able to boost our speed to production by over 50%. The ability to create rich, interactive UI's without the hassle of rolling our own controls has been incredibly valuable. It should also be noted that Telerik's online documentation is rich with examples, tutorials, and real-working demos.
In fact,
The RadAjaxPanel control provides the easiest way to AJAX-enable ASP.NET web controls. You simply need to place the controls that you want Ajax-enabled into a RadAjaxPanel and Telerik RadAjax takes care of the rest. Best of all, this happens transparently to the framework and the controls that are being Ajax-enabled.
