Hi,I am working on Kentico 9.
I want to restrict user to make 3 pinned news only.
I have made Boolean field (checkbox)for pinning news.Now I am getting pinned news firstly appears and rest after that.
Now I want to give limit to user that he can check only three news not more than that. And if he will trying to do check for pinning 4th news then it shows alert.
Please suggest the solution on this.
It will be really helpful.
Thanks in advance.
