Common Controls are a gallery of controls designed for usage in ASP.Net applications. These controls provide a jump-start to the user-interface development of ASP.Net applications. Most of the controls are based on standard ASP.Net controls, enhancing the look&feel and the functionality of the control. These type of controls are the TextBox, NumericTextBox, DataGrid, ImageButton. The gallery also contains controls developed from scratch like the DateSelector and the FtpBox. All of the controls are developed in C#, but they also use html elements and a lot of Javascript.
