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).
