Visual WebGui SDK includes 59 out-of-the-box visual and non-visual User Interface (UI) controls that are implemented for AJAX DHTML. Those exact controls can be used for Silverlight with the addition of the VWG Silverlight SDK.
Visual WebGui complete toolkit allows to rapidly develop high performance web applications with side by side DHTML - Silverlight presentation layers. This means that single development can lead to presenting controls in either presentation layers depending on the browser (VWG Silverlight SDK is required - beta release included within the Professional Studio and the VWG SDK).
Visual WebGui enables the customization and extension of these AJAX controls. Additional controls are available through extensions and more will be added in the future.
Visual WebGui includes an ASP.NET Control Wrapper wizard. This feature allows to enrich the Visual WebGui controls library with any available ASP.NET component including 3rd party control vendors such as Infragistics and DevExpress.
