Questions on ASP.NET 2.0 Controls

Why is there no DataGrid control on the Toolbox?
The DataGrid control has been superseded by the GridView control, which can do everything the DataGrid control does and more. The GridView control features automatic data binding; auto-generation of buttons for selecting, editing, and deleting; automatic sorting; and automatic paging. There is full backward compatibility for the DataGrid control, and pages that use the DataGrid will continue to work as they did in version 1.0 of ASP.NET.
Can I still use the DataList and Repeater controls?
Absolutely. You can use them the way you always have. But note that the controls have been enhanced to be able to interact with data source controls and to use automatic data binding. For example, you can bind a DataList or Repeater control to a SqlDataSource control instead of writing ADO.NET code to access the database.
What's the difference between login controls and Forms authentication?
Login controls are an easy way to implement Forms authentication without having to write any code. For example, the Login control performs the same functions you would normally perform when using the FormsAuthentication class—prompt for user credentials, validate them, and issue the authentication ticket—but with all the functionality wrapped in a control that you can just drag from the Toolbox in Visual Studio. Under the covers, the login control uses the FormsAuthentication class (for example, to issue the authentication ticket) and ASP.NET membership (to validate the user credentials). Naturally, you can still use Forms authentication yourself, and applications you have that currently use it will continue to run.
