Creating a tableView, can't figure out how to identify what table button i click on

Unity Engine

As the title say i have followed a tutorial how to do this and all works well except that i am struggling how to identify and access the buttons i have created. I am able to find the individual buttons using "print (“Name: " + transform.GetChild(10));” so i know they are there. I can also see them hierarchy. The itemPrefab is the button.

The problem is how do i click on a button and by that are able to identify it and manipulate it such as trigger something.

I have one model of button that i use and create the table dynamically.

Here is the code:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;


public class setupScrollableList_Script : MonoBehaviour {

    public GameObject itemPrefab;
    public int itemCount = 10;
    public int columnCount = 1;
    public Scrollbar theScrollBar;
    public InputField theInputField;  

    // Use this for initialization
    void Start () {

        RectTransform rowRectTransform = itemPrefab.GetComponent<RectTransform>();
        RectTransform containerRectTransform = gameObject.GetComponent<RectTransform>();

        //calculate the width and height of each child item.
        float width = containerRectTransform.rect.width / columnCount;
        float ratio = width / rowRectTransform.rect.width;
        float height = rowRectTransform.rect.height * ratio;
        int rowCount = itemCount / columnCount;
        if (itemCount % rowCount > 0)
            rowCount++;
      
        //adjust the height of the container so that it will just barely fit all its children
        float scrollHeight = height * rowCount;
        containerRectTransform.offsetMin = new Vector2(containerRectTransform.offsetMin.x, -scrollHeight / 2);
        containerRectTransform.offsetMax = new Vector2(containerRectTransform.offsetMax.x, scrollHeight / 2);


      
        int j = 0;
        for (int i = 0; i < itemCount; i++)
        {
            //this is used instead of a double for loop because itemCount may not fit perfectly into the rows/columns
            if (i % columnCount == 0) j++;

            //create a new item, name it, and set the parent
            GameObject newItem = Instantiate(itemPrefab) as GameObject;

            newItem.name = "tempBut-" + i;

            newItem.transform.SetParent(gameObject.transform, false);

            //myList[i].transform.SetParent(gameObject.transform, false);

            //move and size the new item
            RectTransform rectTransform = newItem.GetComponent<RectTransform>();
          
            float x = -containerRectTransform.rect.width / 2 + width * (i % columnCount);
            float y = containerRectTransform.rect.height / 2 - height * j;
            rectTransform.offsetMin = new Vector2(x, y);
          
            x = rectTransform.offsetMin.x + width;
            y = rectTransform.offsetMin.y + height;
            rectTransform.offsetMax = new Vector2(x, y);
        }

        // Set the scroll bar so the first item is showed when starting
        theScrollBar.value = 1;


        GameObject xxxx = GameObject.Find ("tempBut-3");

        //print (xxxx.name);


        print (">>> END <<<");



    }

This is probably a very simple problem but i am stuck and would really appreciate some help.

Problem solved, I added an event listener :slight_smile:

for (int i = 0; i < itemCount; i++)
        {
            //this is used instead of a double for loop because itemCount may not fit perfectly into the rows/columns
            if (i % columnCount == 0)
                j++;
           
            //create a new item, name it, and set the parent
            GameObject newItem = Instantiate(itemPrefab) as GameObject;
           
            newItem.transform.SetParent(gameObject.transform, false);
           
            newItem.GetComponentInChildren<Text>().text = "Template-" + i + "  .";
           
            newItem.GetComponent<Button>().onClick.AddListener(
                () => {print ("GET: " + newItem.GetComponentInChildren<Text>().text);});
           
           
            RectTransform rectTransform = newItem.GetComponent<RectTransform>();
           
            float x = -containerRectTransform.rect.width / 2 + width * (i % columnCount);
            float y = containerRectTransform.rect.height / 2 - height * j;
            rectTransform.offsetMin = new Vector2(x, y);
           
            x = rectTransform.offsetMin.x + width;
            y = rectTransform.offsetMin.y + height;
            rectTransform.offsetMax = new Vector2(x, y);
           
        }
