No doubt about it, the Design Time Controls provided by Visual InterDev make it easy to add very nice functionality to your Web pages.
There are also other features in Visual InterDev that let you create attractive Web pages, using the Visual InterDev themes for example. Many times, though, you will either want or need to give your Web pages unique functionality and possibly a distinctive
"look and feel."
To achieve this you will likely write your own code to perform some or all the functions of the Design Time Controls. This way your applications will do precisely what you want, your way.
