Default gallery item always selected

Posted on by jacktherip

I have a searchbox1 and a gallery1. with sharepoint lookup.

if i click an item it then goes to page 2 that uses the selected item to search in galery 2 the second page in a second sharepoint list.

all good.

but.... if i put a button to navigate to the second page without selecting anything in gallery 1 it defaults to gallery1s first item

I have tried all kinds of things to stop it setting default to {} didnt work. I tried resseting gallery1 on the click to go to page 2. still no dice. also tried filtering on the search box

[code]

If(
IsEmpty(Location_Gallery_1.Selected.AreaCode),"", )

[/code]

im a bit lost on how to stop something that would seem to be silly.

When im testing it in the app editor it isnt doing it. but on the actual app it is.

any idea of a way to stop it or clear it?

Hi @jacktherip ,

What is it you expect to happen when navigating to screen2 without selecting any item in the gallery?

The only scenario where a gallery does not have a selected item, is when it doesn't have any items in it at all, so you may have to rethink your design a bit.

When you click on the button, do you want user to navigate to page 2 with Gallery2 showing all items (without gallery1 filter) ?

Hi, what i expected was it to show no items or all items. preferably non as I expect all will mess up the text box.
just one random item that happens to be at the top of a list isnt so helpful 🙂

Hi @jacktherip ,
Then you will have to use collection to store data that you are going to display in page 2 gallery.
On button click you can use ClearCollect(colGal2Items, SPListAssociatedWithGal2)
And when you select any row in your gallery1 you can use below formula on select property on Gallery1:
ClearCollect(colGal2Items, Filter(SPListAssociatedWithGal2, <your filter condition that you are currently using>))

Ahh yes good idea
i just thought of another way possibly and that is to insert a record at the top of the gallery that is blank and use that as the default. 🙂

Easier way here is just set your filter on page 2 to a varSelectedItemID or whatever you are filtering on. And set it with an OnSelect of your first gallery using Set(varSelectedItemID,Self.Selected.ID). That way, you are not basing it on the current selected item of the gallery, but an action from the first one. This way you control that selection using the variable.
