Hello everyone, Before going to my concern i will share the pictures for better understanding.

There are few screens in my app that consists of mark as review. If i mark as review am able to see the count in the label. This works fine.

Now my concern is if i click on the button(blue color), it should navigate to particular screens where i marked as review only.

Can you guys help me out?

Hi @Dishen ,
To navigate to other screen. You simply have to add
Navigate(<Screen Name>, <TransitionType>, <context>(optional)) in your button OnSelect.
That's how you Navigate from 1 screen to other.

To return back to screen.
Add a button/Icon & onSelect property use Back() or Navigate()

Hope this helps you in navigating through screens

Can you please read my concern again ? Because i know how to navigate to the screens but here this is the different scenario. Ex: If i have 4 screens and i put 2 screens mark as review. Now if i press the button, i should be navigated to the screens where i have marked as review only, not all the screens. Thank you

Listen @Dishen ,
You should try to specific in detail since we don't know your requirements with few simple statements.
So as you said, I understand that there are multiple screens having whatsoever controls has 1 checkbox as "Mark as Review" where you need to navigate to those screens where controls are checked.

Note: You can only see 1 screen at a time.

Now, when you mark/unmark the checkbox, use collection to store data to check which screen needs to be reviewed.
As you can see, I have 2 screen.
Checkbox for each screen.
OnSelect of Checkbox
If( App.ActiveScreen.Name in colScreenReview.ScreenName, UpdateIf(colScreenReview, ScreenName = App.ActiveScreen.Name, {ForReview: Checkbox1.Value}), Collect(colScreenReview, {ScreenName: App.ActiveScreen.Name, ForReview: Checkbox1.Value, Screen: 'Review Screen 2'}) )

The gallery on the Home Screen has item property
Filter( colScreenReview, ForReview = true )

the disadvantage is you cannot move through screen with its name. You can insert If condition as an alternative but If you have alot of screens then there will be a lot of if conditions. Post

Hope this helps up to some extent.

I really appreciate for your patience on this task. But i don't have gallery and its my mistake that i haven't said this before. The questions just i have mentioned in label and created one check box. I have only three screens.
Can you please suggest

Hi @Dishen ,
As you see the picture from my previous reply,
I have 2 screens as 'Review Screen 1' & 'Review Screen 2', these consist 1 checkbox and 1 label representing status of review on that screen.
So the formula will work.

I have made a screen with gallery to just show User which Screens has to be reviewed (Marked as Review).
Since you can only move from 1 screen to another, its not feasible to track multiple screens with Review.
That's why I gave an alternative approach.

If your question is "Why have I used Gallery ?"
Ans: I have put up the gallery so that User can see which screen needs to be reviewed and if we click it should navigate me to that screen.

However, you said there's only 3 screens.
Now you can try this...
button onSelect property under Gallery

If( ThisItem.ScreenName = "Review Screen 1", Navigate('Review Screen 1', ScreenTransition.None), If( ThisItem.ScreenName = "Review Screen 2", Navigate('Review Screen 1', ScreenTransition.None) ) )

Add condition and screens accordingly within nested If statements.
Just use the collection data as you like, just like I did using data within gallery.

Also from above reply, you don't need Screen column in collection as feature of Navigating screen using its Name is not available right now.
Maybe in future.

Hope this information helps.
