A field's location is the distance from its upper left corner to the upper left corner of its containing SubSection.
If the field's FieldBase.AutoHeight properties are set to true, the control will automatically adjust the FieldBase.RenderHeight property to fit the field's contents and the FieldBase.RenderTop property of fields below the current field to preserve the vertical distance between fields. The value of the FieldBase.Top and FieldBase.Height properties is not affected.
