Folder Access for SharePoint library in PowerApps

Hi All,

I am building a PowerApps to show the Files and folders in PowerApps. Now, SharePoint library allows you to provide folder level access based upon groups.

How can i implement the same functionality in PowerApps with help of security groups.

 

I have been stuck on it and would appreciate help on this.

Cheers!

@Anonymous ,

This is not helping me to assist you with your problem.
What exactly are you clicking on to navigate and where is is taking you to?

Can you please attach screen shots of both.

@WarrenBelz Sure.

So in the first screenshot is my gallery containing folders. As you can see the navigation button is disabled for the first 2 gallery items and enabled for last 2 items. However, i am still able to navigate to those folders when i click on gallery item in the second screenshot. I would want to disable that feature where in user selects the gallery item and the folders within it are visible in other gallery. They should only be able to navigate through the navigation icon.

Ok @Anonymous ,

I guess I did not use the right terms in asking my question. I am trying to establish the code that is allowing you to navigate. It is clearly on the icon (please confirm this) and you are saying it still works when the icon is disabled?

What is the DisplayMode of your icon and also the OnSelect?

I just did a test this end on a gallery and conditionally disabled an icon and only the enabled ones worked.

@WarrenBelz yes that is correct. My icons have the navigation code however, i am still able to navigate even though my icons are disabled. is it due to some gallery property. 

below is the code on my onselect of icons : 

If(
    vargallery2 = false,
    UpdateContext({vargallery2: true})
);
UpdateContext({vargallery3:false});
UpdateContext({vargallery4:false});
Set(
    folderpath,
    Concatenate(
        ThisItem.'Folder path',
        ThisItem.Name
    )
);
UpdateContext({commentsinput: false})

This is on my icon displaymode: 

If(
    ThisItem.Name = "HR" && Office365Users.MyProfileV2().department = "Human Resource",
    DisplayMode.Edit,
    If(
        ThisItem.Name = "BD & Sales" && Or(
            Office365Users.MyProfileV2().department = "Business Development",
            Office365Users.MyProfileV2().department = "Market Development"
        ),
        DisplayMode.Edit,
        If(
            ThisItem.Name = "General",
            DisplayMode.Edit,
            If(
                ThisItem.Name = "Special Information",
                DisplayMode.Edit,
                Disabled
            )
        )
    )
)

i am still able to navigate to the folder even when my icon is disabled, be it through click of icon of by selecting a gallery item.

@Anonymous ,

That code may have been useful at the start of this thread - you are not navigating anywhere with it, but appear to be setting the Variable folderpath, which I suspect has something to do with the Items of the right panel.

I need to reiterate that disabled items will not trigger any actions - a good test if they are disabled is to hover your mouse over them and see if a "hand" appears - if so they are not disabled.

All of this aside, you can avoid the issue by only changing / setting the folder path if the user is authorised to do it. Using your logic (I have cleaned it up a bit, but have to rely on you that it is correct), you could put the OnSelect of the icon to something like this

UpdateContext(
   {
      vargallery2: true,
      vargallery3:false,
      vargallery4:false,
      commentsinput: false
   }
);
With(
   {   
      wDept:Office365Users.MyProfileV2().department,
      wName:ThsiItem.Name
   },
   If(
      (
         wName = "HR" && 
         wDept = "Human Resource"
      ) ||
      (
         wName = "BD & Sales" && 
         (
            wDept = "Business Development" ||
            wDept = "Market Development"
         )
      ) ||
      wName = "General" ||
      wName = "Special Information",
      Set(
          folderpath,
          ThisItem.'Folder path' & wName
       )
   )
)

@WarrenBelz i have tried the above code in the onselect of my gallery but i would like to bring to your notice that the issue still exsists. I am attaching a gif which shows the issue. 
As you see the navigation buttons are disabled for the above 2 items and enabled for the below two. 

when i select the the disabled items no folder is shown but when i select the enabled navigation button and then select the disabled navigation button the folders are then shown which is not what i want. How can i correct this. Please advice?

@Anonymous ,

There is something corrupt in your gallery - the icon does not work the first time (which is correct), but seems to work after that (which it should not). I assume the Items of the second gallery are folderpath?

The code I gave you should not reset this variable if your user logic is correct (regardless of the icon status) , however it should simply leave the items from the last one. Please have a think through this logic and you will might be able to trace the value changing off a gallery element.

@WarrenBelz that is correct, the item of the second gallery are the folder path.

still not able to figure this out. any help?

@Anonymous ,
As I mentioned I thought I had short-circuited this by only updating the folder path if the user was allowed to and you are saying that does not work either? That actually "takes out" the mode of the icon, so it does not matter if it works or not.

There has to be another control changing the folderpath variable somewhere (otherwise it cannot display the changed content as it is now) and only you can find it  - try to think about every element that get "touched", in particular the gallery and its contents.

@WarrenBelz found the issue. The second gallery items code was indicating gallery1.selected.Name and thus due to that even if the button was disabled selection was possible since gallery selectable property is true. 
I replaced the 2nd gallery items code with a variable that i am setting onselect of navigation arrow and now it is working fine.

 

Thank you for your help!
