Change individual row fill colors in a gallery based on a button in that row

I have a gallery with rows connected to a data source. I would like to change the template fill color of an individual row to green when a button in that row is pressed or the item is selected. I have been able to do this, but it will only change one row at a time to green, and the others remain the default blue color. Once a row has been selected and turns green, I want it to stay green regardless of selecting another row. Any ideas on this? My code so far:

TemplateFill property for the gallery:

If (ThisItem.IsSelected, RGBA(67, 245, 39, .8),
If(!ThisItem.IsSelected, RGBA(39, 174, 245, .8), RGBA(67, 245, 39, .8)
)
)

I also have a button that does some other actions (in each row), so could add actions to the OnSelect property of the button as needed.

Hi @Runner55552,

You can achieve this by making the OnSelect of the gallery and/or the OnSelect of your button save a unique field of that item to a collection. In the example below, I am saving the ID field:

Collect(colSelectedItems, ThisItem.ID)

The Fill property of your items (TemplateFill) should be:
If( ThisItem.ID in colSelectedItems, RGBA(67, 245, 39, .8), RGBA(39, 174, 245, .8) )

If this solves your question, would you be so kind as to accept it as a solution.
Thanks!

One Example

Set your template fill to

If(ThisItem in testRange, RGBA(0, 89, 178, 1), RGBA(0, 89, 178, 0))

adjust colors as needed mine are just to test it out

then onselect of each item should be

If(ThisItem in testRange, Remove(testRange, ThisItem), Collect(testRange, ThisItem))

This worked! The only addition in my case was that I have a dropdown control that a user selects a value, then the gallery is filtered by the dropdown answer. So I added Clear(CollectionName) here so that each time a new selection is made, the Collection is cleared.
