TreeList.RefreshDataSource() Method

Updates the Tree List control to reflect changes made to a data source.

Namespace: DevExpress.XtraTreeList

Assembly: DevExpress.XtraTreeList.v24.2.dll

Declaration

C#

public virtual void RefreshDataSource()

VB.NET

Public Overridable Sub RefreshDataSource

Remarks

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.
