Use the DataSource property to specify the source of values to bind to a data listing control. A data source must be an object that implements either the System.Collections.IEnumerable interface (such as System.Data.DataView, System.Collections.ArrayList, or System.Collections.Hashtable) or the IListSource interface to bind to a control derived from the BaseDataList class. When you set the DataSource property, you must manually write the code to perform data binding.
If the data source specified by the DataSource property contains multiple sources of data, use the DataMember property to specify the specific source to bind to the control. For example, if you have a System.Data.DataSet object with multiple tables, you must specify which table to bind to the control.
