Assembly: DevExpress.Data.Desktop.v22.2.dll

NuGet Packages: DevExpress.Data.Desktop, DevExpress.Win.Dashboard.Design, DevExpress.Win.Design


public static bool PrioritizeIListSourceInDiagramDataBinding { get; set; }

Property Value

Type Description

true, to prioritize the IListSource interface; false, to prioritize the IEnumerable interface.


In v20.1 and earlier, the DiagramControl’s data binding engine prioritizes the IEnumerable interface over the IListSource. This issue prevented data update notifications for data sources that implement both interfaces (for instance, TypedTableBase).

Starting with v20.2, the DiagramControl uses the IListSource.GetList method to obtain data from all sources that implement the IListSource interface. Set the PrioritizeIListSourceInDiagramDataBinding static property to false to revert to the previous behavior.
