Hello !

I am trying to build a tabular view in PowerApps using a gallery embedded (gallery2) within another gallery(gallery1). But I want to be able to select a single record inside the embedded gallery (gallery2)

I have highlighted gallery1 in yellow and gallery2 in red

For example if i select 6 then only 6 should be selected and all other values selected inside gallery2 must be unselected.

Normally a user can select only one record per gallery but since i have embedded a gallery inside another gallery it becomes complicated

You will not be able to have an empty selection on the Gallery. If there is no specific selection, then the first item will always be selected.

You will need to do some tricky workarounds for this to work as you want. Essentially, you will not be relying on the Selected property of the gallery but instead capturing the selection and then comparing.

Example, your OnSelect of the nested gallery would be : UpdateContext({lclSelection: ThisItem.ID})

Then, your TemplateFill property would be:

If(ThisItem.ID = lclSelection, LightSteelBlue, Transparent)

And, when you go to see what is "really" selected, you would refer to the snapshot variable, lclSelection, to get it - not the Gallery itself.

I hope this is helpful for you.
