Object Type	Path to AddNewColumns
OptionsLayoutGrid	.Columns .AddNewColumns

Remarks

This option affects how the control’s layout is restored. Set AddNewColumns to true to retain columns that exist in the current control’s layout but do not exist in the layout being restored. Otherwise, these columns are removed.

Use the OptionsColumnLayout.RemoveOldColumns property to remove the columns that exist in the layout being restored but do not exist in the current control.

Set the OptionsColumnLayout.StoreAllOptions property to true if you want to include the AddNewColumns or RemoveOldColumns property’s settings in the layout when it is saved to storage. These settings are restored when the layout is restored from storage.

Refer to the following help topic for more information on how the AddNewColumns and RemoveOldColumns settings determine the resulting combination of fields in the Pivot Grid’s restored layout: Save and Restore Layout.
