    Default Unanswered: MVC: Iterate through Store in Grid Panel

    Unanswered: MVC: Iterate through Store in Grid Panel


    Hi,

    I want to get the Store from Grid so I can iterate through it, but when I use getStore() method, it returns only String Name of my Store. These are my codes:

    Users.js (Store)
    Code:
    Ext.define('MyApp.store.Users', {
        extend: 'Ext.data.Store',
        
        model: 'MyApp.model.User',
        autoLoad: true,
            
        proxy: {
            type: 'ajax',
            api: {
                read: 'data/data.json'
            },
            reader: {
                type: 'json',
                root: 'UserInfo["User-1"]'
            }
        }
    });
    User.js (Model)
    Code:
    Ext.define('MyApp.model.User', {
        extend: 'Ext.data.Model',
    
        fields: ['0','1','2','3','4','5']
    });
    UserList.js (View)
    Code:
    Ext.define('MyApp.view.UserList' ,{
        extend: 'Ext.grid.Panel',
        alias : 'widget.userlist',
    
        store: 'Users',
            
        initComponent: function() {
                    
            var store = this.getStore(); // store = 'Users' (?)
                    
            this.columns = [
                {header: 'A', dataIndex: '0', flex: 1},
                {header: 'B', dataIndex: '1', flex: 1},
                {header: 'C', dataIndex: '2', flex: 1},
                {header: 'D', dataIndex: '3', flex: 1},
                {header: 'E', dataIndex: '4', flex: 1}
            ];
    
            this.callParent(arguments);
        }
    });
    The grid is showing data without problem, but I don't know how to get Store from it?

    Thank you in Advance.

    Call getStore() after callParent(arguments). Or look it up using StoreMgr manually...

    Thank you mankz,
    It works now. And I got what happens here...

    But why the store is empty?
    I have 3 rows of data in my Grid now.

    Code:
        ...
    
        this.callParent(arguments);
        
        var store = this.getStore();  // store = Store Object ( Empty )
        var count = store.getCount(); // count = 0
        debugger;
    Thank you for your support.
