Does a UI Button in Unity have a location?

I wanted to make a game where you click a button and it affects another button. I made a grid. If I click a button in this grid I want to have it affect another button's image. However I need some sort identifier which tells me which button is which.

enter image description here

I'm used prefabs for a button, then made a 5x10 grid prefab of those prefabs. Any guidance towards the right direction would be helpful even if it does not answer the question thank you.

This can be done easily

First lets make a script GridController.cs

Add a reference to the UI namespace at the top using UnityEngine.UI;

Now place all of your grid items in a parent container(can be an empty gameobject)

Now lets start coding

//Reference parent gameobject
[SerializeField]
private GameObject gridContainer;

//List of all child elements
private List<Button> gridObjects = new List<Button>();

private void Start(){
  //Loop through all children
  for(int i = 0; i < gridContainer.transform.childCount; i++){
    //Add button to list
    gridObjects.Add(gridContainer.transform.getChild(i).gameObject.GetComponent<Button>());
  }

  //Set listeners for buttons

  for(int i = 0; i < gridObjects.Count;i++){
    gridObjects[i].onClick.AddListener(delegate{
      DoSomething();
    });
  }
}

private void DoSomething(){
  //Do Something
}
