Node Expansion Performance Sluggish with 30,000 Child Nodes
posted

Hello,

Is there a way to speed up the expansion of a node that contains 30,000+ child nodes?  It seems ridiculous that each node gets painted, even when the node is not in view (user has to scroll down to see the node).  It currently takes 5-6 seconds to expand the parent node (using v7.3 WinTree)

 Any insight is much appriciated!

Thanks,

 Andrew

    I don't know if you still are dealing with this issue or not, but I do have a suggestion. 

    Instead of using the WinTree, use the WinGrid bound to an UltraWinDataSource with the LoadOnDemand feature.  You can create a tree with the WinDataSource.  I think you will get better performance that way, and your data will still be in a tree.
