Gallery Selection

Posted on by mrichards1371

Hello,

I was watching a YouTube video where it said when using a Gallery and Form, that it's best practice to not set the Form Item to Gallery.Selected. Instead, you should set a variable on the Gallery OnSelect, then reference that variable in the Form Item.

For Example:

Gallery On Select : Set(varForm, ThisItem)

Form Item (varForm).

When I put this in my app and open the screen that has the Gallery and Form on it, it does not show any data until I actually click on one of the Gallery items. How do I set it so it always shows the data of the most recently created Gallery when opening the screen?

@mrichards1371,

In the gallery, I added one Icon (Icon.Edit).

On Select Property of the Icon

Set(varselectedItem,ThisItem);

EditForm(Form1);

// In the same screen itself i have used the form control, if you are using the separate screen u need to use the navigate function as well.

Edit Form Control - Add the respective fields accordingly.

DataSource - ur sharepoint list (in my case its novice)

Item Property - varselectedItem

// This is variable i am using it

Save button

Thank you for your reply @MS.Ragavendar. I may have worded my initial post wrong.

This is what I have on my Gallery OnSelect:

This is what I have on my Form Item:

When I open my app, it defaults the Form to "Getting Data" until I actually click on one of the Gallery items. It's strange because it looks like one of the Gallery items is selected when opening the app.

This issue does not happen when I have Form Item to Gallery.Selected.

I'm curious, what reason did they give for not wanting to use Gallery.Selected? The only one I can come up with is that the Gallery selects the first record when the app loads by default. If you want your form to be blank until someone clicks on something then using a variable would do it. Since you specifically state that you don't want that behavior then I wouldn't use a variable. So to be honest, I don't consider that a best practice. Its extra code for no particular reason and will result in the behavior that you describe. As I said, wanting that behavior is the only reason I can see for using a variable.

Hello @Pstork1,

I am using this variable in my App OnStart section so I can deep link the SharePoint ID. Is there a way to deep link without using this variable? Deep linking is what got me into this mess, I'd much rather be using gallery.selected!

That should work, but only if you start the app using a Deep Link with the parameter included. If you just start the App normally then varID will be blank and the lookup won't work so varRecord will be empty. You need to add something in the App onStart that checks whether the parameter is blank or not. If it is then set varRecord to some known value or Use First() to set it to the first record in the data source.

@Pstork1 Thanks for the suggestion. Now that I have set the varRecord to take the first record in 'New Customer Request' if varID is blank, it is now opening and displaying data on the Form.

I've run into another problem though. On this Gallery, I am filtering out any records that have the status of Complete or Sales Rejected. I show these records on different screens in the app.

Now my app will default to the Form showing a "Complete" record, even though I am filtering out this status in my Gallery. I understand it is doing this because this Complete record is the First in 'New Customer Request' data source, but I'm not sure how to incorporate this filter in my OnStart formula that I showed that the top.

Where you set the first record if you aren't using a deep link, change the 'New Customer Request' datasource to

use the Filter you use in the Gallery. That way the first record won't have Completed as the status.

Hi @mrichards1371,
you can please try this
Coalesce(my_record,Gallery1.Selected) // Here my_record should be replaced with your variable.

I think this works in your case.
