Hi Team,

We load first-level data initially, then click each row to expand.
The data of second level is loaded dynamically. When the data loaded, the position of vertical scroll bar will be back to top.

That is if we change the child items collection, the TreeListView's scroll bars just restore to initial state.

Could you help me to solve this problem, please?

Thanks

Any idea?

Hello Minwei,

The default behavior of the current  version is to reset the position . Since there are a lot of inquiries for that issue , we are going to reconsider the way RadTreeListView behaves for its future versions.
Meanwhile the only workaround I can suggest is to try scroll in to view the desired item , after the operation, using the ScrollIntoView method of RadTreeListView.
