sayali deshpande asked on August 18, 2016 10:39

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.

Hello, You can always display only 3 pinned news ordered by DocumentCreatedWhen or by your custom date field.

You can add the validation for that field or completely hide the checkbox by following macro:

{%Documents.ClassNames("cms.news").WithAllData.Where("pinned=1").Count<3%}

You need to use Order by condition so that the old news are not retrieved. If you are using Repeater to show the news then just type following in the order by property:

DocumentCreatedWhen desc

And thats it. You can also use other fields like NewsRelease column if you have one etc. The DocumentCreaetedWhen is a Kentico field that every page has.

Sayali,

You can modify Jan's code like this by adding an OR clause

{%Documents.ClassNames("cms.news").WithAllData.Where("pinned=1").Count<3 || CMSContext.Current.CurrentDocument.pinned ==1 %}

So this will check for whether no of documents < 3 or if document is already checked.

Try and let us know.

Hi chetan, This code is also not working for me. After implementing this code it allows me to check all news item to pinned. Can you suggest me another way?

Okay sure, I am trying to replicate this locally. I will provide you some update shortly. What I would suggest you is to disable checkbox instead of showing alert. From a UX perspective.
