Error with unbound field


I use a grouping grid in a windows form.
Normaly, it works fine. But when I change a criteria (for example a different date) in the request and reload the grid, sometimes, the grid crash on the unbound field (checkbox). This happens once in a while and I can't figure why. I joint the message with the portion of code where it crash. Someone can help me to solve this issue?

Thanks you.

Hi Anish,

Ia can not reproduce the issue. The problem arise once in a while and I don't know why. The same request will work fine many times and suddenly, that request crash whith no apparent reason. If I try to reproduce it every thing works correctly most of the time.

I compared the example yous sent to me with mine. The only difference is this line:


Is this line can be a clue?

I took out that line from my code and I will make many tests today to see if it change something.

Thank you for your update. 

We tried to reproduce the issue by adding the EnableOneTimePopulate() method in the previous sample but still we couldn’t able to reproduce it. We request you to create a DT incident regarding this, so that our dedicated engineers will work on it and may be able to reproduce the issue. If still the issue didn’t reproduce then our engineers will arrange a web meeting so that we can find the root cause from your end and will be able to give you a solution. 
You can create the DT incident from the following link.
