NuGet Packages: DevExpress.WindowsDesktop.Wpf.Grid.Core, DevExpress.Wpf.Grid.Core

Declaration

C#

public void RefreshData()

VB.NET

Public Sub RefreshData

Remarks

Calling the RefreshData method only makes sense when the bound data source does not support the IBindingList interface. Otherwise, the control will automatically update itself, since such data sources provide data change notifications.
