BaseView.RefreshData() Method

Reloads data into View from the data source.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v18.2.dll

Declaration

C#

public virtual void RefreshData()

VB.NET

Public Overridable Sub RefreshData

Remarks

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

Important

A call to this method during an ongoing data operation (e.g., edit or validation) may cause an exception. To make sure the RefreshData method is executed after a Data Grid completes its current data operations, use the Control.BeginInvoke method.

C#

BeginInvoke(new MethodInvoker(() => {
    myView.RefreshData();
}));

VB.NET

BeginInvoke(New MethodInvoker(Sub() myView.RefreshData()))

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the RefreshData member must not be invoked for these Views. The RefreshData member can only be used with real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.

• GridControl.MainView - returns the top most View in a grid;
• GridControl.FocusedView - returns the focused View;
• GridControl.DefaultView - returns the currently maximized View;
• the sender parameter of View specific events;
• GridView.GetDetailView - returns a detail clone View for a specific master row.
