iam using the same method on another grid and it works fine on all browsers
can u tell me whats wrong with this

Hello maayan,

I already addressed this query in the support ticket you opened, however I will share my reply here as well.
In the current scenario I would recommend using the Hidden option, which guarantees that the columns are included in the column menu. Here is a screencast illustrating the results you'll get with this approach.
