Disable guitexture's object

sup again, guys, i need to disable guitexture, but not just material(otherwise it would be clickable), i need to disable its transform. So how to do it? I have some examples which don’t work:

using UnityEngine;
using System.Collections;

public class DisableButton : MonoBehaviour {

private Transform Buttn;

Void Start() {
Buttn = GameObject.FindGameObjectWithTag("Button").transform;
// i've changed .transform to .object too, unity displayed an error.
Buttn.transform.gameObject.SetActive(false);
// or
Buttn.gameObject.SetActive(false);
}
}

There is no any errors in the script, it just do nothing.

Ah, nevermind, i’ve fixed it by using

Buttn.guiTexture.gameObject.SetActive(false);
