TreeView - The DxTreeViewNode.NavigateUrl property set to an empty URL no longer has an effect.

What Changed

In previous versions, a client web browser navigated to an application's root page when the corresponding node was clicked if you specified an empty URL in the DxTreeViewNode.NavigateUrl property.

Starting with v21.1, you should specify the application's base path in the NavigateUrl property if you want the web browser to navigate to the root page.

Reasons to Change

The TreeView component incorrectly recognized a node's empty URL as the root page's URL.

How to Update Existing Apps

In the NavigateUrl property, specify the application's base path instead of an empty string.
