Gets or sets the LookUpEdit's data source. This is a dependency property.
An object that represents the data source from which the LookUpEdit retrieves its data.
The LookUpEdit cannot operate without a data source. It can be bound to data from a database, from an XML file or to any data created at runtime. The grid can be bound to any object that implements the IEnumerable interface or its descendant (e.g., IList, ICollection). To bind a grid, you should assign a data source to the ItemsSource property. Note that the LookUpEdit cannot be bound at design-time - only at runtime.
