FNCPlanner shows old data sometimes

I have the planner loading my data. It took longer, because often the planner shows the old data (from the dfm). Any attempt at scrolling makes it show the real data.

The only thing I can see different in my code as compared to one of the demos is that

  • I am assigning ViewStart before making the planner visible.
  • The demo is assigning ViewStart after making the planner visible.

Would this cause the symptom?

Please call BeginUpdate / EndUpdate to make sure changes are properly reflected in the planner, also for performance reasons it's better to wrap the code with those methods.

I am doing that in the main initialisation. I am not doing it in Bind_Data method or in the events.

If you have loaded items / data in designtime, it's possible that the loading times are slower. I would suggest to activate your dataset at runtime, to avoid this.
