Posted on by joeljohn

Hi!

What is the best approach to show and Icon if the email of creator is in list. (View if is admin)

I saw some examples (Ticket System) but couldn´t replicate it.

//Set the isAdmin to False on event "onStart"
Set(isAdmin,false);

//Add the admin emails on event "onStart"

ClearCollect(AdminList,"jjohn@mail.com");

//visible properties of Icon

If(MyProfile.Mail in AdminList.Value,true,false);

what am I not seeing?

tx in advance

Hi @joeljohn,

There is a known problem with global and context variables with the screen's OnStart. property. I was able to work around it though. In the OnVisible property of the Screen:

UpdateContext({counter:counter+1})

In the Visible property of your icon

counter=1

The first time the screen is visible, the counter is set to 1 and the Visible property of the icon reduces to true. Every time thereafter, the counter is incremented and will not be 1 again until you close the app and reopen it, simulating the behaviour you desire. If this provides you with a workable answer to your issue, please mark the thread as solved.

Hi and tx for your fast response.

The example you provide me works, but how can i relate this sample with the admin list emails.
For example:

I put a label to debug the results.

The Text properties of the label i set it to : User().Mail and shows the current users emails. The same result if use Office365Users.MyProfile().Mail.
But when i try to create a collection or variable to show the admins emails it does not work.
-Create a collection ClearCollect(AdminList,"jjohn@mail.com");
-Create a variable: Set(MyProfile, User().Email) and set the Text properties equal to: MyProfile but show nothing
On the visible properties of the icon i put: If(MyProfile in AdminList, true, false)---not working, is blank

How can i use your sample to simulate this?

The problem with the OnStart is that you have to save and close powerapps, so changes take effects.
Even so, your answer was right
