Description:

We have encountered an issue with the Kendo UI FileManager component, specifically related to its TreeView functionality. The problem occurs when switching from Grid View to List View within the FileManager interface.

Issue Details:

When a user is working with the Kendo UI FileManager and changes the view from Grid View to List View, the TreeView on the right side of the FileManager continues to expand unexpectedly. This behavior results in an accumulation of TreeView nodes, which are not cleared or updated correctly.

Steps to Reproduce:

  1. Open the Kendo UI FileManager with the TreeView and Grid View.
  2. Switch from Grid View to List View.
  3. Observe the TreeView on the left side.

Expected Behavior:

The TreeView should update appropriately and not exhibit additional, unexpected expansion when changing views.

Attached Video:

A video demonstrating the issue has been attached for reference. It illustrates how the TreeView continues to grow when switching views.

Impact:

This issue affects the user experience by causing confusion and making the FileManager interface less intuitive. It is crucial for the TreeView to function correctly and reflect the current view state accurately.

Hello, Afandi,

The behaviour is due to a known bug which has been fixed for our next release in August. Until then, you can use the 2024.1.130 version as the bug wasn't introduced then.

Let me know if you have any further questions.

Regards,
Martin
