Gets or sets the source containing a list of values used to populate the items within the control.
[Visual Basic]
Public Overridable Property DataSource As Object
[C#]
public virtual object DataSource {get; set;}
[C++]
public: __property virtual Object* get_DataSource();
public: __property virtual void set_DataSource(Object*);
[JScript]
public function get DataSource() : Object;
public function set DataSource(Object); Property Value
An System.Collections.IEnumerable implemented object that contains a collection of values used to supply data to this control. The default value is a null reference (Nothing in Visual Basic).
Remarks
Use the DataSource property to specify the source of values to bind to a data listing control. The data source must be an object that implements the System.Collections.IEnumerable interface (such as System.Data.DataView, System.Collections.ArrayList, and System.Collections.Hashtable) to bind to a control derived from the BaseDataList class.
