Restoring layout in DevExpress PivotGridControl in my WinForms project does not work

Question

I used following code to save and restore DevExpress PivotGridControl V7.2 layout:

//save layout
var fileName = string.Format(@"c:\pivot.xml");
pivotGridControl.SaveLayoutToXml(fileName);

//restore layout
var fileName = string.Format(@"c:\pivot.xml");
pivotGridControl.ForceInitialize();
pivotGridControl.RestoreLayoutFromXml(fileName);

But after running restore code, the layout doesn't change! Has my code any problem?

Thanks to Devexpress Support, following code, solved the problem:

pivotGridControl.OptionsLayout.Columns.RemoveOldColumns = false;

pivotGridControl.RetrieveFields();            
foreach (PivotGridField field in pivotGridControl.Fields) {
    field.Name = "field" + field.FieldName;
}
