We are currently using dhtmlx trees on a control with three trees, each tree is populated from different sources (two different webservices) we're running into several performance issues, one of them being the time it takes to load. We were looking into using telerik's treeview control instead. I tried to do some research on google for performance differences between the two controls (dhtmlx tree and rad tree view) but couldn't find any. Thought this would be the best place to ask. I tried to implement a prototype of that control using telerik's tree view (trial version) and it did seem to load a lot faster. I just need an assurance before we go ahead and purchase the telerik's suite.
