DevExpress controls are highly-optimized for exceptional performance and efficient memory use without the loss of functionality or features. DevExpress ASP.NET controls also support optimizations like HTML compression, callbacks, image sprites, resource caching and sharing.

DevExpress ASP.NET navigation controls use a semantic HTML to keep output clean and minimal. The semantic HTML markup means that web pages are lighter and faster, more search engine friendly and it also gives you better accessibility with screen readers.

Each and every control provides an ability to update the control using callbacks, eliminating the need to re-load the entire page. This callback functionality allows you to optimize how data is transferred to the client.

We also offer you a comprehensive client-side API, along with the ability to handle events on the client side. With our ASP.NET components, you have full control over the control's behavior via client functions.

All DevExpress ASP.NET Controls can be integrated into SharePoint pages. To emulate the default style of SharePoint portals, the DevExpress Aqua Web Theme was specifically designed for SharePoint developers.

Full CSS Support

The appearance of each and every web control produced by Developer Express can be customized using CSS. This approach is the best choice if you need centralized control over the appearance of several controls or the entire site.

DevExpress ASP.NET controls fully support image sprites - all images (except for background and animated images) can be stored as a single image. Sprites are referred to by their position and size within the image. A single request for the specified canvas image is performed to obtain all necessary images, which significantly improves performance.

Additional performance benefits can be achieved by defining image sprite settings within a CSS file and by storing this CSS file as a compressed resource in a themes assembly. This approach is now used by default within all our web controls.
