Hello, 

Following the provided information I can not reproduce the issue that you are experiencing. Can you please elaborate? We offer RadTextBox and RadTextBoxControl as well. Can you specify which is the exact control which you use in your application? Also, I noticed that you use quite an old Telerik version referring back to 2012, it is a very long version gap with the latest 2024 Q3 version. Is it possible for you to upgrade and use more recent Telerik version? We always encourage our clients to upgrade to the latest version in order to benefit from all the improvements in our controls we have introduced so far. However, in order to assist you further it would be necessary first to replicate the exact issue. 

It would be of great help if you can modify the provided project in such a way to demonstrate there the error that you receive, then get the project back to me. Thus, I should be able to investigate it further.

I am looking forward to your reply.

Thank you for your reply. We cannot confirm what specific control was used to cause this issue. It does not occur every time, but every time a window opens and use QR code scanner it crashes. According to the error stack captured (see previous question), the analysis shows that Telerik.wincontrol.dll version is 2012.3.1017.20. Is there a version that fixes this problem and can completely replace the original version without affecting the original interface and code? May I ask if it is possible to provide this DLL separately to verify if it will reappear.

Hello, 

Before proceeding further in investigating a particular issue it is necessary to determine which is the specific control that causes it. Then trying to reproduce the issue with the control in a separate project and environment. Sometimes the issues are related to other application settings or environment specifics. However, without having the exact problem replicated we can not determine what exactly is causing it on your side and can make only assumptions. So initially we should focus on which is the control and try to reproduce the issue, then I should be able to investigate the issue itself. It would be greatly appreciated if you can provie a sample project that replicates the issue, or provide me the exact steps about how to reproduce it on my end so that I can startup building a project. Thank you in advance for your understanding and cooperation. 

As I have already marked in my previous post, you are referring to quite an old Telerik version. Is it possible for you to upgrade to latest one?

Meanwhile you can refer to the following KB article that gives some useful tips about how to get most out of the support when submitting a ticket. I believe it would be valuable in future when submit new posts: How to Get the Most Out of the Telerik UI for WinForms Support - Telerik UI for WinForms

Looking forward to your reply.
