Remarks

XPBindingSource is a lightweight data source for WinForms and WPF runtime-only applications. It binds UI controls and uses XPO sources internally (XPCollection, XPQuery<T> , XPView). You can think of it as an XPO analog of the standard BindingSource.

The XPBindingSource component binds data from a data source to a control and conducts all interaction between the data source and the control. The XPBindingSource was specifically developed for XPO.

XPBindingSource simplifies development for the following use cases:

XPO data sources used on visually inherited Windows Forms and User Controls (KB Article).
Data refresh in persistent objects and collections (documentation).
Immediate data refresh for bound UI controls (KB Article).
Binding to nullable properties (KB Article).
Binding to object references without complex or custom property descriptors (KB Article).
