ProtectIntervalSize
Returns or sets whether to keep the interval size. If the property is set to True, the interval size (the IntervalSize property) will be fixed when changing the element width, but the number of intervals (the Intervals property) will change. If the property is set to False, the number of intervals will be fixed, but the interval size will change. Besides, this property is implicitly set to True after setting the IntervalSize property and to False after setting the Intervals property. The property supports read/write access.
