Welcome to Telerik Sharepoint Demo Application!
This site is a SharePoint Publishing portal. We have modified the master page and replaced the default navigation controls with RadTabStrip and RadPanelbar. The required steps are described in detail in our online documentation. The Corporate section of the SharePoint is utilizing a different master page which incorporates RadMenu and RadTreeView.
Also we prepared three demo pages showcasing RadScheduler, RadEditor and RadGrid working seamlessly in SharePoint. This blog post has all the required steps outlined (installing, getting the UpdatePanel to work). Make sure you read it before using ASP.NET Ajax in your SharePoint site.
