    I have around 8 slots that I use to display working time. Currently there are 700 people (resources) being displayed that share those 8 slots (ie one slot may have up to 700 resources associated with it). At this point I can hardly scroll the scheduleview back and forth or up or down to view data. I do see the Copy method (on my custom slot code) fire almost constantly even when I'm not doing anything. Can someone help me solve this? When I don't add the slots performance seems good.

    Hi,

    RadScheduleView control is not foreseen to work with such a big number of resources and adding Special Slots to those resources could cause performance issues. There are some measures that could be taken into account when using Special and Readonly Slots and they are specified in this help article under the Important section. But even if those measures are taken into account there may still be performance issues as the containers that are rendered for all the Resources, VisibleDays and Special Slots are around 30 000 elements.

    I am also having this issue, but with FAR less resources then the OP. We run into sluggish rendering and scrolling even with only 20-30 resources and 12 special slots per resource. We were able to help the performance by sharing those 12 slots across all the resources but to do this we were forced to overlap special slots and this has another issue of it's own where the z-order is unpredictable.

    Hi Shawn,
