Retaining Gallery Selections after navigating to a new form

Posted on by MZ-18110459-0

I have three galleries on a screen that are linked to related SharePoint Lists.

- The user selects a row in Gallery1 and Gallery2 is filtered based on that result.

- Once a row is selected in Gallery2, Gallery3 is filtered on that result to display related items.

There is a button that takes the user to a newform to add a record to the Sharepoint List related to Gallery3. The selections made in Galleries 1 and 2 on the previous screen are saved to variables and used to prepopulate the newform.

My question is once the new record is submitted and I am returned to the main screen, my galleries are reset. Is there a way to keep the items selected in the galleries visible after the creation of the new record?

Thankyou.

Hi,

You can pass the variables back to the previous screen by adding context variables in the Navigate function like:

Navigate(Screen1, ScreenTransition.Fade, { locSelectedGallery1: varSelectedGallery1, locSelectedGallery2: varSelectedGallery2 })

Assuming that varSelectedGallery1 and varSelectedGallery2 are the variables passed to the second screen.

Then, change the Default property of Gallery1 to locSelectedGallery1 and Gallery2 to locSelectedGallery2.

Also remember you need an operation to clear the variables used as the Default property in the galleries.

Thank you.

This is what I currently have in place. My questions are highlighted in orange below

MainScreen:

Gallery1

OnSelect property, Set(varSelectedGallery1,ThisItem);

Items property, 'List1'

Default property, Defaults('List1')

Gallery2

OnSelect property, Set(varSelectedGallery2,ThisItem);

Items property, Filter('List2', 'ID-From-List2'=Gallery1.Selected.ID)

Default property, {} (Is this what you mean?)

Gallery3

OnSelect property, Set(varSelectedGallery3,ThisItem);

Items property, Filter('List3','ID-From-List3'=Gallery2.Selected.ID)

Default property, {} (Is this what you mean?)

User presses "New Item in List3" button

ResetForm(NewForm);NewForm(NewForm);Navigate(scrnNewForm)

NewForm:

Note, these are dependent Combo Boxes

Combo Box 1

Default property, Blank()

DefaultSelectedItems, LookUp(Choices([@'List3'].'FieldRelatedToList1'), Value = varSelectedGallery1.Title)

Items property, Choices([@'List3'].'FieldRelatedToList1')

OnSelect property,

If the user decides to reselect in this form we want to ignore the variables. I'm resetting to blank here, so I suspect this is the issue when I return to the gallery. Is there a better way to do this?

Reset(DataCardValueCombobox2);

Reset(DataCardValueCombobox3),

Set(varSelectedGallery1,Blank());

Set(varSelectedGallery2,Blank());

Combo Box 2

Default property, Blank()

DefaultSelectedItems, LookUp(Choices([@'List3'].'FieldRelatedToList2'), Value = varSelectedGallery2.Title)

Items property, Filter('List2', 'FieldRelatedtoList1' = DataCardValueCombobox1.Selected.Id)

OnChange property, Reset(DataCardValueCombobox3);

Combo Box 3

Default property, Blank()

DefaultSelectedItems, LookUp(Choices([@'List3'].'FieldRelatedToList3'), Value = LookUp('List4',ID = varSelectedGallery2.IDField,Title))

Items property, Filter('List4', ID = DataCardValueEvComboBox2.Selected.Id,Title)

Once everything is selected, a patch is run and the user is Navigated back to the main screen and I was going to try the suggestion made by jpespena. Do I need to remove the set to blank on the Combo Box 1?

Thank you!

Hi,

Default properties should be:

Gallery1 - varSelectedGallery1

Gallery2 - varSelectedGallery2

Gallery3 - Blank()

And yes, you should remove the Set() functions on the combo box that sets the variables to blank to keep the values when you go back to the previous screen.
