Gallery Controls Help

[More2Learn]

Hello All!

Fairly new to the PowerApps environment and need some assistance with some gallery related controls.  Here is a description of the situation:

I have a screen that has a gallery in it.  When the user selects an item in the gallery I'd like to have a couple of things to happen:

1. When an item is selected, a popup appears with a couple of buttons in it that will direct the user to a form based on their choice.  I'd like for the popup to appear and disappear as the user clicks the selection (like toggling it's visibility on or off, or when they hover over the gallery maybe?).
2. Once the user makes the selection (items are in a Sharepoint List), I need to capture the selection and pass that value to an EditForm when they click the button in the popup.

So far, I've been able to pass a gallery selection to an edit form for updating an existing record using 

Navigate(scr_UpdateForm,ScreenTransition.Fade,{sel_VarEN:ThisItem})

then using

Item = sel_VarEN

to show the selected item in the EditForm.

The problem I'm having is passing that same value to the form through the popup when the button is clicked.  The buttons the user can choose from are Update the Selected Item or Add/Create a Sub-Item for the Selected Item.

Thanks in advance for any assistance ya'll can provide!

Hi @More2Learn ,

Firstly, a better use of the Gallery Variable would be to have the Item of the Form as 

LookUp(
   SPListName,
   ID = sel_VarEN.ID
)

That way, you are querying the list directly and the form will update without re-generating the Variable. I assume selVarEN is a Global Variable.

But to your question - OnSelect

Set(sel_VarEN,ThisItem)

Visible of the pop-up

sel_VarEN.ID = GalleryName.Selected.ID

and then simply Navigate from the pop-up button depending on the button pushed. The Variable is already set. One small item - on the OnVisible of the Gallery screen

Set(sel_VarEN,Blank())

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

WarrenBelz,

Thank you very much for help on this topic!  Hope you enjoyed your Christmas Holiday!

I ended up needing to modify an unrelated gallery to make it work correctly but it works exactly as intended now.  I do have a question though, in the advanced tab / properties for each item in the app do I need to enter functions/items/variables in the order that I want to them to happen, or will all of the items happen when it is called?

The reason that I ask is because I had the Set(sel_VarEN,ThisItem) after the Navigate(...,...) and it didn't work, but when I put the Set() in front of the Navigate() it does.

Navigate(scr_Yadayada,ScreenTransition.Fade);Set(sel_VarEN,ThisItem) > Doesn't Work

Set(sel_VarEN,ThisItem);Navigate(scr_Yadayada,ScreenTransition.Fade) > Does Work

Is there a way to put the Set() inside of the Navigate() so that it happens when the user leaves that screen?  Not sure I need that behavior now, but I'd think it might be useful to be able to do that.

Happy New Year!

Take Care,

Hi @More2Learn ,

You need to Set the variable directly when you select the item - once you navigate off the gallery, ThisItem is no longer relevant, although you could (for what reason I do not know) do this

Navigate(scr_Yadayada,ScreenTransition.Fade);
Set(sel_VarEN,GalleryName.Selected)
