Hi, I have a grouping grid, in which I frequently switch from having groups, to having no groups, and back again. What I need to do is persist the state of what was last expanded so, when I switch back to having groups, the same levels are still expanded. Is there any way of doing this, or am I going to have to do the hard yards and do it all manually

I think you will have to handle this yourself. Doing this for a single grouped column at a time (no nested groups) is probably a modest stroll instead of hard yards. You could iterate through the collection of groups and save a list of the ones that are expanded. Here is a little sample. http://www.syncfusion.com/Support/user/uploads/GGC_PersistGroupExpansion_47066060.zip But to handle this for arbitrary nested groups will require you to turn this into a recursive algorithm which adds some complexity.
