Hello All,

I have 4 pages of different gallery with checkbox. When the user selects 3 checkbox and then moves to next page and selects 2 more checkbox.

When the user tries to go back to page 1 to modify the checked items, the gallery gets resets and all checked box is unchecked.

Users want to go back to see all the checked box results before submitting.

Please advise how to ensure the checked box data is present even if the users go to all the pages and revisits the checked items before Submitting.

Hi @nagaraj007 ,

This is a known issue with checkboxes in a gallery. To avoid this add all the gallery items with checkbox behavior to a collection onSelect of next screen button and when the user comes back you need to validate against the collection.

I hope this resolved your issue if you see any challenge/need further help please let me know I am always happy to do it for my community.

Regards,
Krishna

Hi @nagaraj007 ,

Do you mean that if you navigate to other screens and go back to the previous screen, the checked box will reset to unchecked automatically?

Could you show me all the settings of these screens, galleries, checkboxes?

I've made a similar test but not met the same problem like your description.

Here's my test for your reference:
1)screen1, insert a gallery and a checkbox inside the gallery, a navigate button

set the gallery's Items: list1

set the checkbox's OnCheck:

Collect(test,ThisItem)

set the checkbox's OnUncheck:

RemoveIf(test,ID=ThisItem.ID)

set the navigate button's OnSelect:

Navigate(Screen2)

2)screen2, insert a gallery and a checkbox inside the gallery, a navigate button

set the gallery's Items: list2

set the checkbox's OnCheck:

Collect(test,ThisItem)

set the checkbox's OnUncheck:

RemoveIf(test,ID=ThisItem.ID)

set the navigate button's OnSelect:

Navigate(Screen1)

If I make selections in screen1 and navigate to screen2, make some selections in screen2, click navigate button to navigate back to screen1, the checked items still retain to be checked.

Best regards,

Hi @nagaraj007 ,

I hope you got the idea how to implement this functionality with collections now.

@v-yutliu-msft : Thank you for your reply user has no idea how to use collection so he has not implemented it with collections. I am glad you provided the same solution what I have with me (sorry it is just time zone gap 😊 )

I hope this resolved your issue if you see any challenge/need further help please let me know I am always happy to do it for my community.

Hi @nagaraj007 ,

Add the selected checkboxes to a collection as below:
Collect(collSelected,thisitem)
On Default value of the checkbox add the below formula:
if(isBlank(Lookup(collSelected,ID=thisitem.ID,ID)),false,true)

I hope this resolved your issue if you see any challenge/need further help please let me know I am always happy to do it for my community.
