Updates the Tree List control to reflect changes made to a data source.
Namespace : DevExpress.XtraTreeList
Assembly : DevExpress.XtraTreeList.v25.2.dll
NuGet Packages : DevExpress.Win.Navigation, DevExpress.Win.TreeList
public virtual void RefreshDataSource()
Public Overridable Sub RefreshDataSource
Call the RefreshDataSource method to update data displayed within the Tree List. This method reloads all the records from the Tree List’s associated data source. Note that calling this method makes sense only when the bound data source doesn’t support the IBindingList interface. Otherwise, the control will automatically update itself, since such data sources provide notifications of data changes.
When a Tree List is in the unbound mode, calling the RefreshDataSource method has no effect.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the RefreshDataSource() method.
