observablecollection in ultratimelineView not working properly
posted

Hi,

Im having some performance issues with

ultraCalendarInfo.DataBindingsForAppointments.RefreshData();
ultraCalendarInfo.DataBindingsForOwners.RefreshData(); when  i have over 1000 owners in data source it  take to much to refresh 600ms to 1 sec

I add and remove owners and appointments while i scroll the visible date range. so every time when i scroll i need to refresh the view.

Is there a way to  update only the modified owners and appointments?

I tried observable collection, and work most of case, but im having problems when i remove an owner , it remains visible in View

Any suggestions?

Regards,

Bogdan

    Dear Santa,

     

    Do you have some sample which demonstrates your approach, I don’t think rebinding of data for every scroll is one of the best ideas. In this case you should consider retrieving of the data in background and preloading of the data for the next time slot or something like this. So please send very based and  simple sample which I could review and suggest appropriate.

     

    I am waiting for your feedback.
