When AutoFit is set to a boolean value, that value is returned. Otherwise when AutoFit is left to its default value - null (Nothing in VB) - the current View's ViewBase.DefaultAutoFit value is returned.
For Views where the item size dictates the size available to the RecordPresenter the cells are sized to fit within the record in one or both dimensions based on the View's ViewBase.IsAutoFitHeightSupported and ViewBase.IsAutoFitWidthSupported properties.
For Views such as GridView all the records are constrained in one dimension based on its ViewSettings' GridViewSettings.Orientation. For example, when the Orientation is Vertical all RecordPresenters' widths are set to exactly fit within the control so there will never be a horizontal scrollbar. Likewise, if the Orientation is Horizontal the heights are set to exactly fit within the control so there will never be a vertical scrollbar.
