New Features in ASP.NET 2.0
Crystal Reports project templates (ASP.NET Crystal Reports Website)Visual Studio 2005 has Crystal Report project templates for Visual Basic, C#, and J# WebSites. The project templates create a default Crystal Reports project and start the NewReport Creation Wizard to help new users create reports.
Smart TagsIn Visual Studio 2005, when you add a .NET control to a Web Form, a Smart Tag panelappears. The CrystalReportViewer Smart Tag panel lets you create, open, or edit aCrystal report from a Web or Windows form.
ReportSource and DataSource controls
The ReportSource control contains a report that encapsulates the data, whereas a DataSourcecontrol (such as SqlDataSource) contains the data itself. The ReportSource control is also partof the simplified tag-based application development model provided with ASP.NET version 2.0.
Automatic data bindingWith automatic data binding, you no longer need to call the DataBind() method in the code-behind class when binding to a file directory path through the Properties window.
