Subject Re: [VirtualTreeview] Re: [IBO] Virtual Tree, IBO4 and Delphi6

Just wanted to chime in here and say I tried IB_VTree with VirtualTree and had to make only minor changes for it to display properly, BUT for larger datasets (35,000 nodes) everything came to a complete halt as it was loading.

I moved on to ElTree, but gave up on it because of the poor documentation and slow support. Then, based on Lester's mention, I tried Dream InfoTree. This component actually works. It separates the data from the tree which makes it easier to to use IBO components
(need TDataSet).

It does something interesting with loading where it loads only the 1st root, then when the treeview is displayed and you click on a node, then it loads the next layer. You can turn off this feature, but then I end up with the same problem I had with Virtual Tree,
i.e. with larger datasets, the view never finishes loading.

I mention this to hopefully help with any work you'll be doing on IB_VTree. I really liked VirtualTreeView and would prefer to go back to it, but I'm just not ready to tackle the issues that I ran into with IB_VTree (I'm still very new with Delphi5 programming.).

Please continue with your upgrade!
