onclick.addlistener not working ?

Code (CSharp):

1.  
2.    public void Load()
3.     {
4.         loadpanel.SetActive(true);
5.         string mainpath = Application.persistentDataPath;
6.         DirectoryInfo dir = new DirectoryInfo(mainpath);
7.  
8.         infos = dir.GetFileSystemInfos("*.json").OrderBy(i => i.CreationTime).ToArray();
9.  
10.         for (int i = 0; i < infos.Length; i++)
11.         {
12.           //listLoaditems contains the instatiated prefab containing two text and a button which is the third child.
13.          var delbutton = listLoaditems[i].transform.GetChild(2).GetComponent<Button>();
14.            delbutton.onClick.AddListener(() => LoadDelete(i));
15.         Debug.Log("del name = " + delbutton.name);//Here I am getting correct button name.
16.         }
17.    }
18.    public void LoadDelete(int index)
19.     {
20.         Debug.Log("inndex value = " + index);
21.         Destroy(listLoaditems[index]);
22.         listLoaditems.RemoveAt(index);
23.  
24.        
25.     }
26.  
27.  

I cannot add the onclick listener to the button instantiated.The button is getting detected I believe,I am trying to print button name and the same name for the button in the hierarchy is getting printed.It does not call the LoadDelete function.

 

Can't tell what's wrong with button, code looks ok, if only are you sure there's any button component on child indexed 2? You also have error with your closure. The anonymous function will remember reference to i vairable. The loop will comlete. i will become = infos.Length, after that then handler will be called, the index will be infos.Length all the times.

 

Code (CSharp):

1. int index = i;
2. delbutton.onClick.AddListener(() => LoadDelete(index) );
3.  
4.  

I changed it like this.Still not working.
I manually added a method

Code (CSharp):

1. public void LoadDelete()
2.     {
3.         Debug.Log("Drag n drop method");
4.      
5.     }

I took the prefab and dropped in hierarchy,then selected the button dragged and dropped the component containing the script containing LoadDelete() method and clicked the prefab and gave Applyall .For some reason it is not getting saved

 

The button Onclick in the inspector is always empty even though I click Applyall in the prefab

 

In the ispector only persistent listeners are shown. You won't see those added in runtime I think.

 

Yes I understand that..the one added by dragging the script does show in the button ...but once I make it a prefab and instantiate it the button Onclick goes missing...

Also hit game object name is given as below

Hit Gameobject = TopOutRight

only one button inside the prefab
