DataBinding for Xbase developers in .Net Using Windows.Forms and WPF

Описание: This was presented by Robert van der Hulst at Virtual Fox Fest 2020: https://virtualfoxfest.com/

Whether you have moved your Visual FoxPro application to .Net using X# or you have started new development in .Net using C#, Visual Basic, or X#, you have to learn how .Net binds data from various data sources to its UI elements, such as forms and controls. This mechanism looks a bit like the way FoxPro does it, but is also very different.

In this session, Robert will demonstrate how the various controls and forms in both Windows.Forms and WPF applications can be bound to data in such as way that forms display the data and changes on these controls and forms are written back to the data sources. Some of the topics covered during this session are the mechanism that is used to bind controls and forms to data sources, the requirements for a data source to be "bindable" to controls and forms, and how changes are synchronized between the data source and the UI elements.

The session will look examples of data sources such as:

DataTables and DataViews;
Generic List of Objects;
Classes that implement IList, IBindingList;
DbDataTable() and DbDataSource().

The examples in this session will use X# as the programming language and data in cursors from DBF files, cursors returned from SqlSelect(), and data retrieved directly with the Ado.Net SQL classes. For the UI both Windows.Forms and WPF will be used.
