When a node in a RadTreeView is expanded, its child nodes show correctly, but its bellow nodes which same level show incorrect position. (See screenshot attached).

What can I do about this or is this a bug? (It can run fine in IE 11, but not with other browser like Chrome)

Thank you,

Hi Trong,

Thank you for the screenshot!

Could you please ensure that the Compatibility mode of Internet Explorer is disabled when testing the application? Check out the Different appearance or behavior in Internet Explorer on local and production servers article for more information on the matter.

In addition, it would be helpful if you test with the latest versions of the browsers to ensure the issue is not browser-related.

Such an issue could also be related to some custom CSS on the page. Please try to remove any custom styling and see if the issue persists. 

Inspecting the rendered Html and the applied styles on the page could help in troubleshooting the issue. I would suggest you use the DevTools(F12) of the browser and try to pinpoint what is causing the issue. The first two points in the Improve Your Debugging Skills with Chrome DevTools blog post may help you with that.

If none of these is helping it would be very helpful if you share the markup declaration of the TreeView along with any relevant additional styling.

Looking forward to your reply.

Kind regards,
Doncho

Thanks Doncho for your advice!

Seem that this problem caused by the custom CSS on the page affect to the Telerik treeview:
html:first-child .RadWindow ul{
    float: left !important;

 

It is ok after I fixed it to:
html:first-child .RadWindow ul{
    float: none !important;
