Change button color when click

[JHAKANS]

I have a grid with 200 buttons. 

When you select one button I want to change the fill color to red and then when you click on another button I want the previous button to go back to transparent and the new button to go red. Is it there any easy way to do this? 

The code I run today change the colors but the problem is that the button you clicked stays red until you click it again. I want this to go automatically when pressing a new button. 

Onselect: UpdateContext({pressedButton:!pressedButton})

Fill: If(pressedButton=true; Color.Transparent; Color.Red)

Am assuming your buttons are in a gallery (if not put them in a Gallery with ID ) such as:

ClearCollect(Collection5,

{ID:1},

{ID:2},

{ID:3})

That is, find a way of adding unique field into your table or collection if non existent already. Then put that on the Gallery.

After the above, try:
OnSelect

UpdateContext({pressedButton:ThisItem.ID})

Fill:

If(ThisItem.ID=pressedButton,Red,Transparent)

It's hard to tell what you have in your image...if this is a Gallery, then you can set the TemplateFill property as follows:

If(ThisItem.IsSelected, Red, Transparent)

If it is a button you have (which is not obvious in your image), then you can set the Fill property to the same formula above.

I hope this is helpful for you.
