Hi,

But not on all the applications... any idea ??

Hello,

If this doesn’t happen on every machines, then this issue might  be Operating System related or maybe the Theme of the OS. Have you been able to isolate this in a simple sample and to extract exact step for reproducing of this issue. Also have you tested  the latest Infragistics 13.2 version in order ?

I am waiting for your feedback.

I am unable to reproduce the problem.. it's random

I have opened a Support request: CAS-127483-S6T1Y5

Thank you

I`d like to share our conversation from that case with other community members.

IG:

Thanks for attached stack trace. Could you please answer to the questions below:
1. Did you try to install latest available service release for your version ?

2. Are you using Multiple threads in your application

3. Do you have Creation or Draw Filters ?

4. Are you able to send us sample that reproduce the issue ? "

1-no i can't do that

2-Yes

3-No

4-I am unable to reproduce the problem.. it's random

Thanks for the details. Yes, the threads could cause such random issue, if you didn't managing the threads carefully. The Windows Forms controls are NOT thread-safe ( neither is any DotNet controls ), that`s why you should manage your threads (using Mutex, Semaphores, locks and so on)
I suppose that you are accessing UI objects from a thread other than the one on which they were created. You must be careful not to manipulate any user-interface objects from a different thread. You can also use the control's BeginInvoke method to manipulate UI objects asynchronously. Use the control's InvokeRequired property to determine whether this is necessary.
