Long items get cut off and can't be scrolled to

There are two related issues in this bug report:

  1. TreeView does not allow horizontally scrolling when there are items that extend past the viewport
  2. TreeView cuts off items when the browser is zoomed in

See REPL: https://blazorrepl.telerik.com/wwOHGPvi11wy1OBp06

Steps to reproduce:

  1. Open and run the REPL.
  2. Observe that the last deeply-nested tree item, Design20.......01 is not fully visible (if it is fully visible, just add more 0s in the middle). Specifically, the trailing "1" is not visible and cannot be scrolled to.
  3. Zoom the browser to 200%.
  4. Observe that the TreeView still does not allow horizontal scrolling to view any of the items cut off by the increased zoom.

Hi all,

We have recently reviewed this case. Given that an existing solution is already available and considering the level of demand over the years, I’m closing this issue. If any problems arise in the future, please provide updated details, and we will be happy to re-investigate.

Hi Winston,

Here is a knowledge base article about Blazor TreeView horizontal and vertical scrolling. It explains the observed behavior and suggests a few options to proceed.
