Gets or sets a value indicating whether items of the current row field should be shown in outline form.
true, to show field items in outline form; otherwise, false.
The Outline property is relevant only when the specified field is a row field other than the innermost one. In this case, setting this property to true changes the field layout to outline form. If the Outline property is false, the field is shown in tabular form.
To display item labels from the next row field in the same column as the current field (compact form), set both the Outline and PivotFieldLayout.Compact properties to true.
For an outer row field in outline or compact form, you can also specify the subtotal position by using the PivotFieldLayout.SubtotalOnTop property.
