When user change one of "MinTimeRulerExtent" or "MinorTickLength" or "MajorTickLength" VisibleRangeChangedCommand executed!
I load appointment in lazy mode. so each change causes to load appointment again.....
when VisibleRange doesn't change.....why VisibleRangeChangedCommand execute!
You are correct, the VisibleRangeChangedCommand is needlessly executed when the most of the properties in the ViewDefinition are changed. This is a bug in RadScheduleView and we will do our best to fix it for one of the upcoming internal builds.
