DisplayMode based on user

[tianaranjo]

Greetings, 

I have a feedback form and I would like the Status card display as with edit option for managers or as view only if not a manager.  I have added a list from SharePoint with the manager names in a screen that will not be visible to the user.  Can you please advise on the function for the Status DisplayMode?

Thank you.

To check whether the current user is in that list of manager names, you can use the in operator.

Reference: https://docs.microsoft.com/en-us/powerapps/functions/operators#in-and-exactin-operators

So, you can do something like this:

If( User().FullName in ManagerNames,
    DisplayMode.Edit,
    DisplayMode.View
)

Although, I don't suggest using DisplayMode.View. Using DisplayMode.Disabled is easier since you can customize formatting easier that way.

For performance reasons you may want to set the User() to a variable to decrease the number of calls to that function. I know there are other posts out there explaining all the reasons why but by doing this it speeds up the app considerably.

For example on page Visible on your Home screen run:

Set(CurrentUser, User())

Then anytime you ever need to find the user just simply do a CurrentUser.FullName etc. That way you are only calling the User() function once.

Otherwise @Anonymous has the right idea, you can display, hide, disable just about anything based on username using the code he supplied.
