Posted 27 November 2020, 1:13 am ESTThe project requires a tree control to show hierarchical data. We are using Wijmo Angular tree component. We expect the control to perform well in case number of items to be shown are in the range of a few tens of thousands at a level of hierarchy in tree. In one of our case, there is a tree node having 50K items as children nodes. We tried for around 5K items as children nodes and it is failing miserably.
I was going through the documentation of Wijmo library but couldn’t decipher if Angular tree control implements UI virtualization or not. Usually this technique is implemented to reduce browser overhead of creating DOM elements and reusing the item renderers to show items appearing in viewport. This is more often than not implemented in datagrid/tree controls.
Can you please confirm if this feature is available in Wijmo ’s Angular tree control? Let me know.
