Hi HeeJun Lee
I would really like to assist you on your way but the problem is that I cannot understand you. Could you please clarify what you have in mind when saying:"To behaving selection of RadTabItem, program have more memory. When behaving with only code, memory is not increase.
Are you referring to the physical memory that your application takes or you refer to the loading time? Also I could not understand what you need to say with your second post: "When data binding, occure the problem.
" Please elaborate more on that matter.
If it would be easier for you, please reproduce the issue in a small repro project and send it over along with steps which reproduce the reported behavior. This will better help us to understand your scenario.
