this is my controller Ext.define('List.controller.Main', { extend: 'Ext.app.Controller',

config: {
    refs: {
        main: 'mainpanel'
    },
    control: {
        'presidentlist': {
            disclose: 'showDetail'
        }
    }
},

showDetail: function(list, record) {
    this.getMain().push({
        xtype: 'presidentdetail',
        title: record.fullName(),
        data: record.getData()
    })
}

}); This is my model

Ext.define('List.model.President', {
extend: 'Ext.data.Model',
config: {
    fields: ['firstName', 'middleInitial', 'lastName']
},

fullName: function() {
    var d = this.data,
    names = [
        d.firstName,
        (!d.middleInitial ? "" : d.middleInitial + "."),
        d.lastName
    ];
    return names.join(" ");
}

});

this is my store

Ext.define('List.store.Presidents', {
extend: 'Ext.data.Store',

config: {
    model: 'List.model.President',
    sorters: 'lastName',
    grouper : function(record) {
        return record.get('lastName')[0];
    },
    data: [
        { firstName: "George", lastName: "Washington" },
        { firstName: "John", lastName: "Adams" },
        { firstName: "Thomas", lastName: "Jefferson" },
        { firstName: "James", lastName: "Madison" },


    ]
}

}); this is my views, under my view folder,

Ext.define('List.view.Main', {
extend: 'Ext.navigation.View',
xtype: 'mainpanel',
requires: [
    'List.view.PresidentList',
    'List.view.PresidentDetail'
],

config: {
    items: [{
        xtype: 'presidentlist'
    }]
}

});

still under my view folder PresidentDetail

Ext.define('List.view.PresidentDetail', {
extend: 'Ext.Panel',
xtype: 'presidentdetail',

config: {
    title: 'Details',
    styleHtmlContent: true,
    scrollable: 'vertical',
    tpl: [
        'Why Not Work {firstName}  {lastName}!'
    ]
}

});

still under my view folder i have another file called PresidentList

Ext.define('List.view.PresidentList', {
extend: 'Ext.List',
xtype: 'presidentlist',
requires: ['List.store.Presidents'],

config: {
     xtype:'container',
    title: 'Why Not Work',
    grouped: true,
    itemTpl: '{firstName} {lastName}',
    styleHtmlContent: true,
    store: 'Presidents',
    onItemDisclosure: true,

     items: [

            {

            xtype: 'searchfield',
                name:'searchfield',
                placeHolder:'Search',
            },

         {

            xtype: 'spacer',
               height: 25
            },
           ] 
}

});

This is my App.js file

Ext.application({ name: 'List',

requires: [
    'Ext.field.Search'
],

controllers: ['Main'],
views:  ['Main'],
stores: ['Presidents'],
models: ['President'],

launch: function() {
    Ext.Viewport.add({
        xtype: 'mainpanel'
    });
}

Thanks for your assistance.

Answer 1

You actually need to listen for modifications on search field and filter the store based on the value.

This is the kind of modification you need to make to your controller:

config: {
    refs: {
        main: 'mainpanel'
    },
    control: {
        'presidentlist': {
            disclose: 'showDetail'
        },

        'searchfield': {
            keyup: 'doSearch'
        }
    }
},

showDetail: function(list, record) {
    this.getMain().push({
        xtype: 'presidentdetail',
        title: record.fullName(),
        data: record.getData()
    })
},

doSearch: function(field) {
    var value   = field.getValue(),
        store   = this.getPresidentList().getStore(),
        query   = new RegExp(value, 'i');

    store.filter('firstName', query)
}

Also, I would add another field to the model that combines first and last name (e.g. fullName) and search against it.
