How to restore grid focus after data reload in ExtJS?

I have a view in ExtJS that contains a grid where the user can select an entry plus some panel with details about the currently selected row. Each time another row is selected the view is reloaded, which causes the grid to loose input focus for keyboard navigation.
How can I reload grid store data and keep input focus on the grid? My model defines idProperty and thus the correct row gets selected, but column selection and input focus gets lost. I am using ExtJS v7.3.0.55 with the Classic Triton theme.
Example
Extend the code in the existing Grid with JSON Store Sencha Fiddle with a data model and some grid event listener to reproduce the issue:
Ext.application({
name: 'Fiddle',
launch: function () {
// My data model with custom ID field
Ext.define('User', {
extend: 'Ext.data.Model',
fields: [
{name: 'name', type: 'string'},
{name: 'email', type: 'string'},
{name: 'phone', type: 'string'},
],
idProperty: 'email',
});
Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
model: 'User',
proxy: {
type: 'ajax',
// Loading data from ./simpsons.json in the fiddle ./Data folder.
url: 'simpsons.json',
reader: {
type: 'json',
rootProperty: 'items'
}
}
});
Ext.create('Ext.grid.Panel', {
renderTo: Ext.getBody(),
height: 300,
width: "100%",
title: 'Simpsons',
store: 'simpsonsStore',
autoLoad: true,
columns: [{
text: 'Name',
dataIndex: 'name'
}, {
text: 'Email',
dataIndex: 'email',
flex: 1
}, {
text: 'Phone',
dataIndex: 'phone'
}],
// Add some event handler to reload grid data, restore selected row
listeners: {
select: function (sender) {
console.log('grid selection update');
var record = sender.getSelected();
var store = sender.getStore();
store.load();
// This will restore the selected row, but grid focus is lost
sender.setSelected(record);
}
}
});
}
});

Try to put the selection in the store`s load handler:
Ext.create('Ext.grid.Panel', {
renderTo: Ext.getBody(),
height: 300,
width: "100%",
title: 'Simpsons',
// Using Named Store
store: 'simpsonsStore',
// Load the data
autoLoad: true,
columns: [{
text: 'Name',
dataIndex: 'name'
}, {
text: 'Email',
dataIndex: 'email',
flex: 1
}, {
text: 'Phone',
dataIndex: 'phone'
}],
listeners: {
select: function (selectionRowModel, selectedRecord, selectedIndex) {
var store = selectionRowModel.getStore();
store.on('load', function(store) {
selectionRowModel.select(selectedIndex, true, true);
}, this, {
single: true
})
store.load();
}
}
});

Sencha Touch 2: Reloading a treeStore in nestedList to reflect user selection

I have a nested list in my application, and when users make a selection they are taken to a detailCard with some options. One of these options is to "confirm" their selection. Once confirmed, the selection should be removed from the list. This works on the server side, so if the app is refreshed the selection is gone. However I was hoping to remove the selection in the treeStore itself and refresh the view somehow so that users can immediately see the effect of their confirmation. I was following a tutorial for nestedList that I can't seem to find anymore, and this code is based on that:
var itemId = '';
Ext.define('MyApp.view.MainView',
{
extend: 'Ext.tab.Panel',
xtype: 'main',
alias: "widget.mainview",
requires: [
'Ext.dataview.NestedList',
'Ext.data.proxy.JsonP'
],
config:
{
tabBarPosition: 'bottom',
items: [
{
xtype: 'nestedlist',
title: 'Listings',
iconCls: 'home',
displayField: 'listingValue',
scrollable: true,
detailCard:
{
xtype: 'panel',
scrollable: true,
styleHtmlContent: true,
items: [
{
xtype: 'fieldset',
readOnly: true,
title: 'Schedule Information:',
items: [
{
name: 'from',
id: 'from',
xtype: 'textareafield',
label: 'From',
readOnly: true
},
{
name: 'to',
id: 'to',
xtype: 'textareafield',
label: 'To',
readOnly: true
},
{
name: 'moreInfo',
id: 'moreinfo',
xtype: 'textfield',
label: 'More Info',
readOnly: true
},
]
},
{
xtype: 'container',
flex: 1,
items: [
{
xtype: 'button',
text: 'Confirm',
action: 'confirmSelection',
margin: '10 5',
padding: '5',
ui: 'confirm'
}]
}]
},
listeners:
{
itemtap: function (nestedList, list, index,
element, post)
{
var detailCard = this.getDetailCard();
detailCard.setHtml('');
itemId = post.get('id');
Ext.getCmp('from').setValue(post.get(
'from'));
Ext.getCmp('to').setValue(post.get('to'));
Ext.getCmp('moreinfo').setValue(post.get(
'moreinfo'));
}
},
store:
{
type: 'tree',
fields: [
'id', 'from', 'to', 'fromcity', 'tocity',
'time', 'address',
{
name: 'leaf',
defaultValue: true
},
{
name: 'listingValue',
convert: function (value, record)
{
listingValue = '$<b>' + record.get(
'address') + '</b> ' + record
.get('fromcity') + ' to ' +
record.get('tocity');
return listingValue;
}
}
],
root:
{
leaf: false
},
proxy:
{
type: 'jsonp',
url: 'http://myURL.com/page.php?action=go',
reader:
{
type: 'json',
rootProperty: 'root'
}
}
}
},
{
title: 'Dashboard',
iconCls: 'action',
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Dashboard'
},
]
}]
}
});
I have no idea what to do at this point, because the store is set up in the view and I'm not sure how to access it in my controller. I learned about treeStore.removeAll() and treeStore.load(), but how can I call those functions in a controller when the store is set up without any type of reference name? Is there a way I can remove the user's selection and display the view, or perhaps reload the view altogether so it can retrieve the new list from the server?

Because my list is on the first page of my app, I managed to get away with window.location.reload(); and reloading the whole app. Its not the most elegant solution, but the changes are reflected.
I won't accept my own answer just yet in case someone comes along with a better solution.

How can I get the id in Extjs checkcolumn?

Im tiro in Extjs.
That is my model:
Ext.define('CatModel', {
extend: 'Ext.data.Model',
idProperty: 'id',
fields: [{
name: "name",
convert: undefined
}, {
name: "id",
convert: undefined
}]
});
store:
var store = Ext.create('Ext.data.TreeStore', {
model:'CatModel',
root: {
expanded: true
},
proxy: {
type: 'ajax',
reader: 'json',
url: 'item_access.jsp?fullpage=true&show_cat=1'
}
});
and treePanel:
var treePanel = Ext.create('Ext.tree.Panel', {
id: 'tree-panel',
title: 'Sample Layouts',
region:'north',
split: true,
height: 560,
minSize: 150,
rootVisible: false,
autoScroll: true,
store: store,
columns: [
{
xtype: 'treecolumn',
text: 'name',
flex: 2.5,
sortable: true,
dataIndex: 'name'
},
{
text: 'id',//I want to get this id
flex: 1,
dataIndex: 'id',
sortable: true
}
, {
xtype: 'checkcolumn',
text: 'Done',
dataIndex: 'done',
width: 55,
stopSelection: false,
menuDisabled: true,
listeners:{
checkchange:function(cc,ix,isChecked){
//alert(isChecked);
//I want to get this row id in here
}
}
}]
});
In checkchange function there are three parameter one unknown,two is index, and three is check status ...
So how can I get the the same row id where I check the checkbox??
Can I find that id number by checkbox row index??

You should be able to get the record from the TreeView with the row index, and then get the id property from it:
listeners:{
checkchange: function(col, idx, isChecked) {
var view = treePanel.getView(),
record = view.getRecord(view.getNode(idx));
console.log(record.get('id'));
}
}

ExtJS store, cannot load data to grid

Console is clear. Grid is empty (only column titles are shown). How can I check if data is correctly loaded to the store? It seems to me that the store's autoLoad method is not triggered somehow. Here is the grid:
Ext.define('NameSpace.view.Clients', {
requires: [
'Ext.tree.Panel',
'Ext.grid.Panel'
],
extend: 'Ext.tab.Panel',
title: 'Clients',
alias: 'widget.viewClients',
items: [
{
xtype: 'panel',
title: 'All Clients',
layout: {
type: 'hbox',
align: 'stretch'
},
items: [
{
xtype: 'treepanel',
title: 'Tree Panel',
width: 200,
resizable: true
},
{
xtype: 'gridpanel',
title: 'Clients List',
store: Ext.getStore('storeClients'),
flex: '1',
columns: [
{ text: 'Name', dataIndex: 'first_name' },
{ text: 'Last Name', dataIndex: 'last_name' },
{ text: 'Phone Number', dataIndex: 'phone' }
]
}
]
}
],
initComponent: function () {
this.callParent(arguments);
}
});
And here is the store (Model contains nothing but extend and fields configs):
Ext.define('NameSpace.store.Clients', {
extend: 'Ext.data.JsonStore',
proxy: {
type: 'ajax',
url: 'http://test.local/client',
reader: {
type: 'json',
root: 'records'
}
},
autoLoad: true,
constructor: function (config) {
this.initConfig(config);
}
});
Ext.create('NameSpace.store.Clients', {
model: 'Clients',
storeId: 'storeClients'
});

Move
model: 'Clients',
storeId: 'storeClients'
into store definition, and get rid of store creation call. Store will be created automatically.

Why do you override the store constructor?
If you actually need to do it, you should add this.callParent(arguments) to the constructor, otherwise the original constructor (which does a lot) won't run.

You just need to change
store: Ext.getStore('storeClients')
To This :
store: 'Clients'

I think you need to write field when you create store.
i.e.
fields:[ 'first_name', 'last_name', 'phone']

ExtJs 4 Grid Paging

I'm trying to make data grid with paging using ExtJs framework, but unfortunately my code doesn't work. Maybe some of you has already settled this such problem.
Json-reply from server is:
{
"totalCount":"2",
"companies":[
{
"id":"1",
"name":"Name1",
"region":"Reg1",
"address":"Addr1",
"dealCount":"3",
"dealAmount":"19250",
"latestDealDate":"2012-01-09"
},
{
"id":"2",
"name":"Name2",
"region":"Reg2",
"address":"Addr2",
"dealCount":"2",
"dealAmount":"12150",
"latestDealDate":"2012-01-08"
}
]
}
JavaScript code, which creates store, grid, e.t.c. is:
Ext.require([
'Ext.grid.*',
'Ext.data.*',
'Ext.util.*',
'Ext.toolbar.Paging',
'Ext.ModelManager',
'Ext.layout.*'
]);
Ext.onReady(function(){
// Define data model
Ext.define('Company', {
extend: 'Ext.data.Model',
fields: [
{
name: 'id',
type: 'int'
},
'name', 'region', 'address',
{
name: 'dealCount',
type: 'int'
},
{
name: 'dealAmount',
type: 'int'
},
{
name: 'latestDealDate',
type: 'string'
}
],
idProperty: 'id'
});
// Create data store
var companies = Ext.create('Ext.data.Store', {
pageSize: 50,
model: 'Company',
proxy: Ext.create('Ext.data.proxy.Ajax', {
url: 'service/companies-data.php'
}),
reader: Ext.create('Ext.data.reader.Json', {
root: 'companies',
totalProperty: 'totalCount'
}),
sorters: [{
property: 'name',
direction: 'ASC'
}]
});
// Create data grid
var grid = Ext.create('Ext.grid.Panel', {
renderTo: Ext.getBody(),
width: 700,
height: 500,
store: companies,
columns: [
{
text: 'Name',
dataIndex: 'name'
},
{
text: 'Region',
dataIndex: 'region'
},
{
text: 'Address',
dataIndex: 'address'
},
{
text: 'Deal Count',
dataIndex: 'dealCount'
},
{
text: 'Deal Amount',
dataIndex: 'dealAmount'
},
{
text: 'Latest Deal Date',
dataIndex: 'latestDealDate'
}
],
bbar: Ext.create('Ext.PagingToolbar', {
store: companies,
displayInfo: true,
displayMsg: 'Displaying topics {0} - {1} of {2}',
emptyMsg: "No topics to display"
})
});
// Load first data page
companies.loadPage(1);
});
Firebug shows, that server responds with json-data, but grid remains empty. How can I fix it?

You should define reader inside proxy (at least that helped for me). Eg:
proxy: Ext.create('Ext.data.proxy.Ajax', {
url: 'service/companies-data.php',
reader: Ext.create('Ext.data.reader.Json', {
root: 'companies',
totalProperty: 'totalCount'
})
})
