Hi,

I have implemented the treeview which has roughly 3000 to 5000 multilevel json objects.The treeview takes lots of time to load and render and fails sometimes. I have some concerns in implementing the treeview,

* I had to apply checkbox checkchildren option to keep the selected & unselected nodes.

* I couldn't apply neither loadondemand nor remote data binding option since i wanted whole datasource for storing and retrieving purpose from the db.

If I apply checkchildren option the browser hangs and kills the script. The treeview loading faster if checkchildren is set to false. I have tried with setTimeout option to enable the checkchildren after loading the treeview, but again it hangs whenever its getting applied to the treeview.

I have an example from this below link.

Kindly let me know if is there any work around or solutions to solve this issue. Thanks.

Hello Paulraj,

Thank you for providing a sample

We are currently researching TreeView performance optimizations. We will review the described scenario with checkChildren configuration. However, keep in mind that the performance of toggling checked state depends also on the JavaScript engine of the browser and the CPU power of the machine.

I will update this thread once we finalize the research and what are the improvements made in the TreeView widget. Currently, the only feasible approach for improving performance is enabling loadOnDemand setting.
