All our ASP.NET components support Themes - a feature that allows you to change the look and behavior of a control with just a single mouse click. This is not much of a benefit by itself though. Since this is a standard feature supported by many ASP.NET components, similarly to other vendors, we didn't have to do much to support it.

Themes may not seem to be a great feature at first glance. Here is what they do. They look for special folders that hold resources and property values for a control. When you choose a particular folder, all those settings take effect. The functionality looks pretty simple, especially when you try the built-in Themes of standard controls. If you try GridView, for instance, you'll see that row colors and fonts change - and that's it.

Obviously, Theme support alone doesn't deliver much value. That's why we go much further than the standard implementation of other 3rd party control vendors by delivering the following features that do make a difference:

Delivered as a Single Separate Assembly

We ship our built-in Themes packed in a single DLL file - ASPxThemes. It contains all theme files (such as skins, CSS and image files), as embedded resources. This gives your site performance benefits: a reduced web server traffic, because shorter resource URLs are used; the enabling of resource compressions and merging options affect files stored in a themes assembly. This also makes it easier to deploy built-in Themes with our components: all you need is to copy the ASPxThemes assembly file, rather than deal with multiple CSS files and images in a hierarchical folder structure.

Modify Existing or Create Custom Themes

Using the ASPxThemeBuilder tool shipped with the installation, you can easily create custom themes basing them on any desired built-in DevExpress Theme. The Theme Builder allows you to modify the created or previously saved theme by selecting individual controls and their elements, and changing their images, CSS and skin settings in a visual manner.

You can save a modified theme to a desired folder. Moreover, with the Theme Builder, you can even generate a custom assembly for your theme to then be used in your web project.
