Hide AllThe IList Binding sample uses CollectionBase class, with implementation of IList interface to create a ProductCollection class which gets populated from the Products table of the NWind database. The created ProductCollection is used as a database for binding data to the DataGridView control.The data from ProductCollection class gets displayed using the DataSource property of DataGridView control. On clicking the Generate Report button, the ProductCollection class is again used to display the data of the generated report in a Viewer control. Similarly, you can display a report by binding to the DataSource property of a report.
