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