Hi....

I am using a RadTreeView.

- Menu groups collapse when I click a sub menu item.

Expected:
- Menu group should stay open until I
click the divot to collapse the menu group
OR
click the divot to expand a different menu group
OR
go to a different tab.

This is working fine on localhost but not on server. If there is any change to be done in code while loading on server please let me know..
I am storing the value of node in session, to check if the node is clicked or not.

Hello Munish,

In order to find what is causing this unusual behavior I will need some additional information. For your convenience I will list a couple of questions as follows:

• Considering that your projects is working fine on localhost, could you please provide us a live url with your deployed application to investigate it locally?
• In case you are not able to provide it, it would be really helpful if you send us a video which demonstrates the issue(you may Jing) . This is freeware screenshot and screencast software and it is really easy to use.

I have attached the screenshots for both the pages. One is for server and other for localhost. You can see on the left side on the local page the menu remains expandeded when add contact sub menu item is clicked but on server menu group collapses.

Hello Munish,

In your case it will be hard to inspect this problem from the provided screenshots. Could you please provide us at least one of the listed options:

• Live URL with your deployed applications, so I can inspect that unusual behavior.
• Sample project or demo, so I can review your code.

I hope this blog post will be helpful to send us a isolated project ready to be inspected.

Hello Munish,

Unfortunately we are not supporting RadControls "Classic" anymore. According to our official support policy, which can be accessed here, those controls have Extended Support state. In case there is a problem with them, we are not providing any fixes, updates and etc. Of course you could start using RadControls for Asp.net Ajax, which are  fully supported.

Independently, we were unable to run your project locally. Let me suggest you an option in your case:

• You can send us a runnable project, which demonstrates the problem, so we can examine it at our side or deploy it to our server for further inspection.

I hope, that you will find this information helpful.

Regards,
Boyan Dimitrov
