How to load dynamic data in a list/table inside a panel-EXTJS

I'm trying to create a panel like:
with the below code as a beginning, however I'm not sure how can I create a list/table inside a panel in a way like it looks below in the image.
I also have to load the data dynamically inside the panel.
also I'm using panel since I want it to be a collapsible one
$cls.superclass.constructor.call(this, Ext.apply({
items: [
this.section({
items: [
this.panel = new Ext.Panel({
items: [
this.section({
items: []
})
],
collapsible: true,
})
]
})
]
}, cfg));
Ext.extend($cls, Panel, {
getData: function(data) {
//here I have the entire data I want to show in the list. just not sure how?
}
});
any ideas?

You can create custom rows with Ext.Panel. The example shows only show creating list. To add part where AND, OR you can change structure of data and create row with nested panel row.
Here is example of creating custom list with panel:
Ext.onReady(function () {
Ext.create({
xtype: 'panel',
renderTo: Ext.getBody(),
title: 'ExtJS Master Panel',
items: [
collapsibleList = new Ext.Panel({
title: 'Collapsible List',
collapsible: true,
hideBorders: true,
padding: '10px',
height: 400
})
],
getData: function () {
return new Promise(function (resolve) {
setTimeout(function () {
resolve([{
name: 'Last VM Scan',
decider: 'LESS THAN',
period: '30 days'
}, {
name: 'Last CERTVIEW Scan',
decider: 'LESS THAN',
period: '14 day'
}, {
name: 'Last checked In',
decider: 'LESS THAN',
period: '10 days'
}]);
}, 1000);
});
},
listeners: {
afterrender: function () {
console.log(collapsibleList);
Promise.resolve(this.getData()).then(function (data) {
for (var i = 0; i < data.length; i++) {
var pan = new Ext.Panel({
xtype: 'panel',
layout: 'hbox',
hideBorders: true,
items: [{
xtype: 'panel',
padding: '10px',
width: 200,
items: [{
xtype: 'label',
text: data[i].name
}]
}, {
xtype: 'panel',
padding: '10px',
width: 300,
items: [{
xtype: 'label',
text: data[i].decider
}]
}, {
xtype: 'panel',
padding: '10px',
items: [{
xtype: 'label',
text: data[i].period
}]
}]
});
collapsibleList.add(pan);
}
collapsibleList.doLayout();
});
}
}
});
});

EXTJS Form : How to only update record, not whole record

I made a edit form, to update a comments array with a new comment. Everything good so far.
The store is from MongoDB.
The record has an ISO date, and when I update it, changes it to a string.
From this:
"tmx" : ISODate("2015-07-19T00:26:53.000Z")
to this:
"tmx" : "Sun Jul 19 2015 00:55:23 GMT+0100 (Hora de Verão de GMT)"
Sample record:
"tmx" : ISODate("2015-07-19T00:26:53.000Z"),
"comments" : [{
"comment" : "tury",
"date" : "2015-11-19T01:15:13.552Z"
}]
My form:
var form = new Ext.form.FormPanel({
width: 500,
items: [{
xtype: 'grid',
store: storearray,
margin: "0 0 10 0",
columns: [{
id: 'comment',
header: "Text",
autoSizeColumn: true,
flex: 1,
sortable: true,
dataIndex: 'comment'
}, {
id: 'date',
header: "Date",
dateFormat: 'm-d-Y g:i A',
autoSizeColumn: true,
flex: 1,
sortable: true,
dataIndex: 'date'
}],
layout: {
type: 'fit',
align: 'stretch'
}
}, {
xtype: 'textarea',
id: 'new',
text: 'Add Comment',
style: 'width: 100%',
fieldLabel: 'Add Comment',
layout: {},
name: 'comment'
}],
dockedItems: [{
xtype: 'toolbar',
flex: 1,
dock: 'bottom',
ui: 'footer',
layout: {
pack: 'end',
type: 'hbox'
},
items: [{
xtype: 'button',
text: 'Cancel',
itemId: 'cancel',
iconCls: 'cancel'
}, {
xtype: 'button',
text: 'Save',
itemId: 'save',
iconCls: 'save',
handler: function (form, rowIndex, colIndex) {
var recform = this.up('form').getForm().getRecord();
var names = recform.get('comments');
var arraysize = names.length;
var val = Ext.getCmp('new').getValue();
var actual = new Date().toISOString();
if(val == "") {
alert('Comentario Vazio');
} else {
names.push({'comment': val, 'date': actual});
recform.save();
var newRecord = store.sync();
this.up('form').getForm().setRecord(newRecord);
this.up('form').refresh();
}
}
}]
}]
});
What I want to do, is just update the field or let my date maintains in ISODate format. and the new comment date be inserted asISODate too.
Any advice?

Update particular field in record/model:
set( fieldName, newValue, [options] ) : String[]
Sets the given field to the given value, marks the instance as dirty
Source: Extjs model
In your example if i understand correctly make something like this:
var recform = this.up('form').getForm().getRecord();
var actual = new Date().toISOString();
recform.set('comments', actual);

Ext JS GridPanel edit textfield width too narrow

I have a JSFiddle Demo which creates a Grid with editing enabled. The problem I am facing is that the textfields that are displayed when editing a row are too narrow. They are about half the column width.
// Data to be bound to the grid.

In your fiddle you use javascript from Ext JS 4.2.0 version but CSS from Ext JS 4.0.2a version.
You always should use javascript files and CSS from same version of Ext JS framework. Otherwise you can get unexpected results as you can see in your fiddle.
When I setup your fiddle with javascript and CSS from Ext JS 4.2.1 version, everything works without problems: https://fiddle.sencha.com/#fiddle/3ft

extjs4 get instance of view in controller?

I am trying to get an instance of my view within the controller. How can I accomplish this. The main reason I am trying to do this is that I have a grid in my view that I want to disable until a selection from a combobox is made so I need to have access to the instance of the view.
Help?
My controller:
Ext.define('STK.controller.SiteSelectController', {
extend: 'Ext.app.Controller',
stores: ['Inventory', 'Stacker', 'Stackers'],
models: ['Inventory', 'Stackers'],
views: ['scheduler.Scheduler'],
refs: [{
ref: 'stackerselect',
selector: 'panel'
}],
init: function () {
this.control({
'viewport > panel': {
render: this.onPanelRendered
}
});
},
/* render all default functionality */
onPanelRendered: function () {
var view = this.getView('Scheduler'); // this is null?
}
});
My view:
Ext.Loader.setConfig({
enabled: true
});
Ext.Loader.setPath('Ext.ux', '/extjs/examples/ux');
Ext.require([
'Ext.ux.grid.FiltersFeature',
'Ext.ux.LiveSearchGridPanel']);
var filters = {
ftype: 'filters',
autoReload: false,
encode: false,
local: true
};
Ext.define('invtGrid', {
extend: 'Ext.ux.LiveSearchGridPanel',
alias: 'widget.inventorylist',
title: 'Inventory List',
store: 'Inventory',
multiSelect: true,
padding: 20,
viewConfig: {
plugins: {
ptype: 'gridviewdragdrop',
dragGroup: 'invtGridDDGroup',
dropGroup: 'stackerGridDDGroup'
},
listeners: {
drop: function (node, data, dropRec, dropPosition) {
var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('ordNum') : ' on empty view';
}
}
},

sortable: true,
dataIndex: 'ordNum',
flex: 1,
filterable: true
}, {

dataIndex: 'item',
flex: 1,

}]
});
Ext.define('stackerGrid', {

}
}
},

}, {

}],

dock: 'bottom',
items: [{
text: 'Submit',
action: 'submit'
}, {
text: 'Reset',
action: 'reset'
}]
}, {
xtype: 'toolbar',
dock: 'top',
items: [{
id: 'combo',
xtype: 'combobox',
queryMode: 'local',
fieldLabel: 'Stacker',
displayField: 'stk',
valueField: 'stk',
editable: false,
store: 'Stackers',
region: 'center',
type: 'absolute'
}]
}]
});
Ext.define('STK.view.scheduler.Scheduler', {
extend: 'Ext.panel.Panel',
alias: 'widget.schedulerview',
title: "Scheduler Panel",
layout: {
type: 'column'
},
items: [{
xtype: 'inventorylist',
width: 650,
height: 600,
columnWidth: 0.5,
align: 'stretch'
}, {
xtype: 'stackerselect',
width: 650,
height: 600,
columnWidth: 0.5
}]
});

As I said, Extjs creates getter for your views (those listed in the controller's view array) and you get access to them:
var view = this.getSchedulerSchedulerView();
Once you have the view reference you can do this to get access to the contained grid:
var grid = view.down('.inventorylist');
grid.disable();

Extjs layout extension causing error in ext-all.js

I am trying to learn Extjs and I am immediately coming up with an issue. My Html has ext-base.js and ext-all.js correctly included. I then have the following in my js file:
Ext.BLANK_IMAGE_URL = '<%= Url.Content("~/Content/ext/images/default/s.gif") %>';
Ext.ns('MyNamespace');
Ext.onReady(function() {
alert("onReady() fired");
});
So far everything is working, no errors and the alert is thrown correctly. I then add the following code after onReady:
MyNamespace.BaseLayout = Ext.Extend(Ext.Viewport({
layout: 'border',
items: [
new Ext.BoxComponent({
region: 'north',
height: 32,
autoEl: {
tag: 'div',
html: '<p>North</p>'
}
})
]
}));
This causes the following javascript error in chrome:
Uncaught TypeError: Object #<an Object> has no method 'addEvents' ext-all.js:7
Ext.Component ext-all.js:7
Ext.apply.extend.K ext-base.js:7
Ext.apply.extend.K ext-base.js:7
Ext.apply.extend.K ext-base.js:7
(anonymous function) MyApp.js:13 (pointing to the Ext.Extend line)
If I take the Viewport code and put it directly into the OnReady function it (like the following)
Ext.onReady(function () {
var bl = new Ext.Viewport({
layout: 'border',
items: [
new Ext.BoxComponent({
region: 'north',
height: 32,
autoEl: {
tag: 'div',
html: '<p>North</p>'
}
})
]
});
});
It works. Can anyone clue me in to what I am doing wrong with the Extend method?

To fix your code, the issue is simply bad syntax in the Extend statement. You need a comma after Ext.Viewport, not an extra () pair:
MyNamespace.BaseLayout = Ext.Extend(Ext.Viewport, {
layout: 'border',
items: [
new Ext.BoxComponent({
region: 'north',
height: 32,
autoEl: {
tag: 'div',
html: '<p>North</p>'
}
})
]
});
However, I'd suggest taking #r-dub's advice and reading up more on what you're trying to do.

Here's a bit more complicated example of what you're trying to accomplish. I'd strongly suggest taking a look at Saki's 3 part series in building large apps with ExtJS, it'll help you understand how it use extend properly to create re-usable components.
Ext.ns('MyNamespace');
MyNamespace.BaseLayout = Ext.extend(Ext.Viewport, {
initComponent:function() {
var config = {
layout: 'border',
items: [
new Ext.BoxComponent({
region: 'north',
height: 32,
autoEl: {
tag: 'div',
html: '<p>North</p>'
}
})
]
};
Ext.apply(this, Ext.apply(this.initialConfig, config));
MyNamespace.BaseLayout.superclass.initComponent.apply(this,arguments);
}//end initComponent
});
//this will give you an xtype to call this component by.
Ext.reg('baselayout',MyNamespace.BaseLayout);
Ext.onReady(function() {
new MyNamespace.BaseLayout({});
});

ExtJS recommend the use of define instead of extend. Here is how a similar example works with define:
Ext.define('Grid', {
extend: 'Ext.grid.Panel',
config: {
height: 2000
},
applyHeight: function (height) {
return height;
}
});
new Grid({
store: store,
columns: [{
text: 'Department',
dataIndex: 'DepartmentName',
renderer: function (val, meta, record) {
return '' + record.data.DepartmentName + '';
},
width: 440,
flex: 1,
filter: 'string',
sortable: true,
hideable: false
}, {
text: 'Department Code',
dataIndex: 'DepartmentKey',
width: 100,
flex: 1,
filter: 'string',
sortable: true,
hideable: false
}, {
text: 'Main Phone',
dataIndex: 'MainPhone',
flex: 1,
filter: 'string',
sortable: true,
hideable: false
}, {

dataIndex: 'RoomLocation',

}, {

dataIndex: 'HideawayPhone',
flex: 1,
filter: 'string',
sortable: true,
hideable: false
}, {
text: 'Has OEC',
dataIndex: 'OECFlag',
xtype: 'checkcolumn',
width: 50,
filter: {
type: 'boolean',
active: true
},
flex: 1,
sortable: true,
hideable: false
},
{
text: 'Action',
dataIndex: 'ID',
renderer: function (value) {
return 'Edit';
},
hideable: false
}],
forceFit: false,
split: true,
renderTo: 'departmentSearchGrid',

});
