StartScreen for SharePoint list form customized in Power Apps

[bhajan]

Hello All,

I searched my query in the PA forum but could not find what I am trying to achieve.

Scenario:

I have 2 screens namely screen A and screen B. The screen A has to be displayed when new button from SP list is clicked. The screen B has to be displayed when edit button from SP list is clicked.

Note: In tree view in power apps studio first screen is screenA.

What I tried:

When I click on new button it works fine. It opens screen A. But when I edit any list item then first it opens screen A and gets redirected to screen B. After researching I found start screen function in app object in Power Apps. Here I have tried below code in start screen function.

If(IsBlank(SharePointIntegration.Selected),ScreenA,ScreenB)

But its not working. Please help me! Why its not opening respective screen directly

Thank you!

Set a variable on new button example Set(var1,"new")

Set a variable on Edit button example Set(var1,"edit")

If(var1="new",ScreenA,If(var1="edit",ScreenB))

Please accept the solution if this helped you out

Thank you for your reply.

I tried the same but its showing "Global variables are not allowed in StartScreen".

OnNew - NewForm(SharePointForm1)

OnEdit - EditForm(SharePointForm1)

Is above code set on your SharePointIntegration OnNew and OnEdit ?

Hi @bhajan,

You need to leverage the SharePoint ID column to get this done. Try below formula on your app 'StartScreen' property. It should work for you:
If(IsBlank(SharePointIntegration.Selected.ID),EditFormScreen2,NewFormScreen1)

Thank you for your reply.

I have commented all the code in OnNew and OnEdit and set your code in StartScreen but now its showing only screen A all the time even if I click on edit button as well.

Hi @bhajan,

I have tried from my side and it worked for me without any issue.

1. In SP, Onclick on New button, it navigated to Screen1

2. For Edit, Seleted a record in SP and clicked on 'Edit' option it navigated to Screen2

Is this you are trying?

@bapala 

Yes I am trying the same.

Let me explain this again. The complete requirement is shown in image below.

So, On new button click from SP list, Screen A should be displayed and on clicking save button from screen A, It should redirect to screen B. This i am able to do.

But when i click on edit button it goes to screen A and then in 1 second redirects to screen B.

I am trying to achieve is when i click on edit button, directly it should open screen B.

Has anyone found a solution for this? I'm trying the exact same thing and I'm having the exact same problem as @bhajan .

To recap: I'm using a standard SharePoint list with a PA custom form. If the user clicks on the 'New' button (in the standard SharePoint list, NOT in the custom form!! this is very important because some people here are giving wrong suggestions), I want the form to open on screen A. If the user clicks on the 'Edit' button in the standard list, I want the form to open on screen B. To avoid any confusion, I am talking about these two buttons in the SP list command bar. 

These buttons cannot be referenced inside PowerApps as far as I know, so it's not possible to set an OnSelect or any other property.

In the App.StartScreen property I have the following code:

For debugging purposes I have added a label on the form that says true or false to indicate whether or not the if-condition is true.

However, no matter which case - true or false - the form always opens on screen A. I've been pulling my hair out over this.

I have tried all the variations you can think of, including IsBlank(SharePointIntegration.SelectedItemID) or IsEmpty(SharePointIntegration.Selected.Title) or whatever... the result remains the same.

I tried to work around this by putting a Navigate statement in scrA.OnVisible that would navigate to scrB if selected item was not blank, but apparently you're not allowed to use Navigate() in the OnVisible property. You cannot use Navigate() in the App.OnStart property, either so... I've no idea how else I can get this to work.

I feel like the above code should work and that this is a bug...

Oh btw, I have also set the OnNew and OnEdit properties of the SharePointIntegration connector to the correct screens, but this makes no difference whatsoever.

Any tips would be greatly appreciated because this really does look and feel like a bug to me...
