How to make an inventory Paging on Unity C# ?

Question

Hi everyones,

How to make an inventory with 3 Storage. For example :

if i push storage 1 button it will show 20 Slots at inventory,

if i push storage 2 button it will show from 21 Slots until 40 Slots at inventory, and

if i push storage 3 button it will show from 41 Slots until 60 Slots at inventory.

so it have all 60 slots total.

Below its my code :

inventory.cs

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine.UI;
 
 public class inventory : MonoBehaviour {
     public List<GameObject> slotsx = new List<GameObject> ();
     public player Player;
     public List<item> itemx = new List<item> ();
     public GameObject slots;

     item itemxs;
     public int indexofdragitem;
     public Sprite icon;
   
     int sisa;
     itemDatabase database;
     int totalSlot = 60;
     int currentStorage = 1;
     int view = 20;
 
     // Use this for initialization
     void Start () {
         Player = new player();
         int slotAmount = 0;
         database = GameObject.FindGameObjectWithTag ("itemDatabase").GetComponent<itemDatabase> ();
 
 
         //Generate the Slot and Slot Name;
         for(int i = 1; i <= 60; i++) {
                 GameObject Slot = (GameObject) Instantiate(slots);
                 Slot.GetComponent<slotScript>().slotNumber = slotAmount;
                 
                 slotsx.Add(Slot);
                 
                 Player.items.Add(new item());
                 addChilParent (this.gameObject,Slot);
                 //Slot.transform.parent = this.gameObject.transform;
                 Slot.name = "slot-" + i;
                 slotAmount++;
 
         }
 
     }
 
     //Add Slot Child To GridSlot Game Object
     public void addChilParent(GameObject parentx, GameObject childx) {
         childx.transform.SetParent (parentx.gameObject.transform);
     }
  
 }

Thanks

Paging can easily be achieve with LINQ, for example:

 int pageLimit = 20;
 IEnumerable<item> items = new List<item>(); 
 // then populate your items as you usually would.

 IEnumerable<item> GetPagedItems(int pageNum)
 {
     return items.skip((pageNum - 1) * pageLimit).Take(pageLimit);
 }
