Hi Forstmeier  

Thank you for contacting Syncfusion Support. 

We have checked the reported case with TreeViewAdv and we faced the reported scrolling issue with TreeViewAdv when Virtualization is enabled. So we have planned to revamp the scrolling calculation in Virtualization mode and revamp the implementation of TreeViewAdv. We planned to complete this by end of December, 2018.  

We appreciate your patience until then.

Hi,

I'm having the same problems with scrolling in TreeViewAdv when virtualization is enabled.

Do you have any solution for it?

Thanks

Hi Ondra, 

 

The improvement for this reported problem is under proper tracking in our side. Based on our analysis process, we need to do some improvements in our Virtualization feature to solve this scenario. Hence we will update you more details on April 8, 2019.

Please let us know if you require further assistance.

Hi Ondra,

Thanks for your patience.

As per your request, we are trying to implement your requirement regarding improving the performance of TreeViewAdv. This improvement would require some major changes in our existing architecture hence it takes a considerable amount of time to implement as considering the stability of our control. We have planned complete this implementation for our Volume 3, 2019 release.

We appreciate your patience until then.
