[@shreyapandey1671]

Hi Shane, M following u last 1 yr and ur all videos is very useful & helpful. I've one query, m not able to find anywhere. My scenario is- 1. I've 11 PowerApps applications in same tenant. 2. I created 11 separate apps. I used 1 app as Master app, in Masterapp there is 10 SubApps. 3. Suppose 5 users have permission for only 5 SubApps but the problem is they (5 users) can also see the rest of 5 SubApps icon. 4. they don't have permission but still they can able to see those Apps icons, bcoz that all Subapps link in same screen whenever they click on those icon, it ask the permission. 5. So what i want is, Who don't have permission, they cannot able to see those apps icon. SOLUTION is there any way, they can only find those apps or they can only see those apps icon, which have had permission.

[@ShanesCows]

Not that I know of. YOu will need to write logic to manage that yourself.

[@jenn4256]

I ran into the issue that the button will still be available for about 1 to 2 seconds to individuals not in my Access Control list (mine is called Voters list) and of course someone went in to click on it right away before it disappeared. Not sure if anyone else had this issue, but I fixed it by making a varAccess variable on app start that saves the boolean value when compared to my Voters list. Then I put the button on an inner screen so that it is automatically invisible and does not even pop up for the 1 to 2 seconds while the app loads and decides the value. This is my app on start line: Set(varUser, User().Email); Set(varAccess,!IsBlank(LookUp(Voters, Title = varUser).Title)) and then my vote button is just visible set to varAccess. Thanks so much for your help with this video!!

[@DanielADamico]

Hi Shane, good video! However, I would like to see you giving more examples of security using CDS instead of SharePoint. Using Power apps along with SharePoint lists to control security is not a good idea because as you know, the users of the app will need to have access to the SharePoint lists and they could easily change the list contents and bypass the app security you implemented.... 😊

[@ShanesCows]

I am working on a proper CDS intro series. So many little things to cover to do it well.

[@travellingstu]

They only need view access to the list for this to work

@@travellingstu This is true for this example, but often you'll also have personal/confidential information that sometimes you don't want to be shared/viewed by other users.. ☹️☹️

Shane, Thank you kindly for your well explained video. I am intrigued by the external list of email address you used for the visible buttons.

[@jlemoo2]

I have this same question. Why should I need to explicitly type an email address when I can get it from the properties of a person object? I've been at it for a day now, and it tells me that the PersonColumn.Email returns a table, and not a text value. I do it LookUp('SharePoint List Name',Title = "Plant Manager", Name).Email, where "Name" is a column of type "Person." I should get the email of the Plant Manager this way, but nope, just an error about it being a table, and how I cannot compare that to a text value. I'll do a workaround by adding an Email column to my table, so I can do LookUp('SharePoint List Name',Title = "Plant Manager").Email and that works, but I don't think I should need to do that. In Shane's example, he manually types the email into his list, which seems a little bit error-prone to me.

Juan I thought I showed in this video how to query a list. But you are right I never did a video on security groups. 😑

[@juanjo2391]

Not a huge issue, I can create a power automate flow to fill a list with the members of an AD group, however it would be cool to create different roles in an app and manage it easier 😃

[@hpchristener]

Thank you for this video. The show/hide switching somehow doesn't work properly in my app: for some of the eligible persons the button is shown and for some of the same list it is not. It even happens that the button is shown and later the same day it is no longer visible. What could be wrong?

[@ShanesCows]

Try adding labels to the app to see what is happening when it is running

[@hpchristener]

@@ShanesCows Thank for answering. I was loading those users from a SharePoint list into a collection and from there in a variable. All of them were shown in the collection but not all of them in the variable. Now using !IsBlank(LookUp(KLBBackOffice;Title=varCurrentUserEmail;Title)) as shown in your video solved the problem.

[@verdijason11]

Hey Shane - have you used (display:none;) functionality within Power Apps instead of (visible:none;) ? I'm achieving Visible: none; - what I need is Display:none; Because the element still takes up the same space when not visible.

[@ShanesCows]

Hey Jason I don't think Display.None is possible. I think you have to do Visible. If you need something to move up then you would need to write dynamic formulas for X and Y of hte object you want to move. Possible but a lot of moving parts

Share, in InfoPath I was able to do similar logic to hide a section (of controls). Can sections be created in Power Apps? Do you have a demo that shows how to do this?

How would I disable the button based on the date picker value? If I selected a date say 2nd April 2021 and I don't want the user to click the button till he reaches 2nd April 2021. Now the app user is sitting on 24th March 2021.

Why doesn’t varUserEmail work in my power app? It doesn’t even turn blue?

[@ShanesCows]

Did you create it on App OnStart?

[@tedmeyer4231]

Hi Shane, good stuff. I am curious about load time. I built an app for my company and it has several buttons on the home screen. Each is either visible or not based on an access list value. When the app is first opened, the buttons all appear for a brief second and then they hide based on the evaluation. Is there a way to overcome this?

[@ShanesCows]

You could put a spinner on the visible of the screen that delays things a second or two? Not sure, you might just have to get creative. I don’t think any of the apps I do this in have the issue but I have seen it before

[@justinabel6733]

Is there a way to lookup by current user and then check to see if that columns "yes/no" field is set to yes to display the button?

[@ShanesCows]

That is shown in this video, you will need to slightly pivot and change your LookUp to have a criteria of Field = yes

[@illmatic1668]

Hi Shane, thanks for this! I am running into an issue i can't seem to figure out. When testing on a label, the LookUp formula as entered always returns blank instead of printing an email. PowerApps always tells me no records can be found even though records exist. Do you know what would cause this? Thanks in advance.

[@ShanesCows]

I would guess you have a typo in your lookup.

[@jaimearturomartinezcervant4059]

I'm building an app that has its data source in SharePoint, how can I hide a button when an item in the list is empty? Example my list in Sharepoint has 3 columns and 1 of them is empty.

[@ShanesCows]

Use the IsBlank function to test 😎

[@jaimearturomartinezcervant4059]

In the event Visible?

@@ShanesCows I am trying to make an IconEdit active if the Attachment column is empty, that is, if there is an attachment the IconEdit is not shown as active and if it is empty it is enabled.

[@patricknassar3790]

Hi Shane, Thank you for this info. One question. I am putting "varUserEmail" as the replacement for "User().Email" (discussed around the 6min mark). I have done everything you said but when I put varUserEmail in the code, my button stays disappeared. It works with "User().Email". And no error pops up. Any suggestions?

[@ShanesCows]

Did you make sure that there is a value stored in the variable?

[@samratguha8933]

1 more question I had in mind is that is it possible o control the visibility of a field based on a SharePoint Group (suppose if I don't belong to Group XYZ I can't edit/view some fields)

[@ShanesCows]

There is no easy way to reference SharePoint Groups. Maybe via Graph API.
