One display form for multiple galleries

[Anonymous]

I was just wondering i have one page with a display form that populates with selected records from galleryA, but i have multiple galleries connected to the same datasource, is there a way to populate this display form from each of these galleries?! Because each gallery is connected to the same datasource, but the display form only lets me populate selected items from one gallery.

Thanks

Yes, there are actually a few ways to do this, but I would suggest using "context" within the Navigate( ) command.

For example, you can have each gallery navigate to the Display Form Page like so:
Navigate( 'DisplayFormPage', None, {View: ThisItem})

Then have the Items in your Display Form = View.

Note: View is just a variable name. You can change to to whatever you wish, so long as you keep it consistent among all your pages

To help you understand what is happening a bit more, in your Display Form, the Items are probably set to "GalleryA.Selected". So, when you select a Record from GalleryA, your DisplayForm updates itself with the selected Record. This is why you if you navigate to the Display Form from GalleryB, you will see the same selection from GalleryA (or nothing at all if you haven't chosen anything from GalleryA yet).

If you send in a context via a variable name from all of your galleries and then have your Display Form update itself based on the variable name, then you can successfully navigate to your Display Form Page from any Gallery with the necessary information passed in. For example, if GalleryA, GalleryB, and GalleryC each have a navigate command that states Navigate('DisplayFormPage, None, {View: ThisItem}), when you set DisplayForm Items = View, the Display Form will update itself based on the View it receives from any page. 

I hope this explanation helps. Hopefully I answered your question. If you need anything else in regards to this, feel free to ask.

This (One display form for multiple galleries) was very helpful thank you.

However, I have struck a problem when attemtping to Edit anything from one of multiple Galleries.

So the by creating a variable "View" I have successfully pass a form from 1 of many galleries in the BrowseScreen.

Now when I try to edit any selected form, it pulls it from one specific gallery ... which I later learned that it was because the EditForm1 Item reads BrowseGalleryMM12.Selected which is one of the galleries.

I have tried appliying a similar principle by attempting ot create another variable Edit but I am clearly in over my head.

Any advice to pull a form from one of many galleries and then pass it thru to Edit would be greatly appreciate.

Many thanks

@davidjsfrazer,

I believe that there are two ways you can do this.

The first option is having the navigate command say something along the lines of Navigate('Edit Page', None, {Edit: View}). Then have the selected item of the Edit_Form on that page be Edit.

Or, you can use the Patch( ) function to edit each field for the variable Edit.

Let me know if you need any more explanation on either of those two - I can help walk you through it some more.

Holy Cow!!!!

Thank you so much for the rapid response and SOLUTION.

Your first point worked perfectly! I'm not sure I'd successfully be able to execute your second point (the Patch() function) as my knowledge and experience is VERY limited.



Thanks again TonyHart... works a TREAT!



So to summarise, I've added a diagram that will hopefully help others ... assuming there are other numpties like me out there 🙂

Otherwise, I've done it for myself.

Hi,

My form is based upon a sharepoint list which uses many dropdowns (Choice fields). Unfortunatley, when I created my custom cards and imported these fields, whilst they look correct and lookup the values, when I choose a value then save the form, it clears the field box before it saves. Furthermore, if I attempt to edit an existing form (becuase I can open it in edit mode now thanks to the help in this thread) the drop down opens with the correct choice values but when I select and save it reverts back to previous value and then closes.

It appears that all of my Custom Cards are behaving the same way ... input or dropdown??

Any clues as to where I might be going wrong please? I have provided a couple of screen shots (settings followed by the behaviour):

Many thanks

Hi @davidjsfrazer,

I'm not certain right off of the top of my head what is causing your fields to not function properly. I would have to look into it a bit more, but unfortunately I don't think I would have the time to. I would searching through the forums for someone who might've run into a similar problem, or post a new issue. 

If you don't have time to do that though, I would suggest looking into the Patch( ) function. I've worked around my edit forms not working multiple times by using that. Here Microsoft's page for more info on it: https://powerapps.microsoft.com/en-us/tutorials/function-patch/

Best of luck!

Thanks for all of your help on this thread TonyHart.

I've no clue how to apply the Patch() function but I did notice that each field did not have a parent element in the Custom Card. I think that is where I went wrong.

As a result, I have removed all of my custom cards and simply imported the Sharepoint Cards and edited them directly ... not quite how I wanted to go about it but achieved the right result nonetheless.

Thanks again

@davidjsfrazer,

Glad you got the results you wanted! Congrats on figuring it out!

@Anonymous I am having issues with the info you gave David.

I too have two browse screens (one all items and one a filtered list).  Everything goes to the detail screen correctly from both browsers and I set my "edit icon" on the details page how you suggested.  No problems there.

However when I go to the EditForm1 and change the Item to Edit it gives me an error saying "Invalid Formula. Expected a vlue compatible with 'DataSource'"

Any thoughts what I am missing?  Thanks
