If I add a button to my panel via a 'renderTo' argument (See 'b' below), it works perfectly :
//create div in javascript
var extJSTest = document.createElement('div');
//append to main
mainPanel.appendChild(extJSTest);
//'get' panel through EXT (just adds a wrapper?)
var myDiv = Ext.get(extJSTest);
var b = Ext.create('Ext.Button', {
text: 'Click me!!!!',
renderTo: myDiv,
handler: function() {
alert('You clicked the button!')
}
});
However, if, I replace the 'b' with the following code (That is, i want to replace the button with a grid, connected up with a SimpleStore and some data)...
var myData = [
['Apple',29.89],
['Ext',83.81]
];
var ds = new Ext.data.SimpleStore({
fields: [
{name: 'company'},
{name: 'price'}
]
});
ds.loadData(myData);
var grid = new Ext.grid.GridPanel({
store: ds,
columns: [
{header: "Company", width: 120, dataIndex: 'company'},
{header: "Price", width: 90, dataIndex: 'price'}
],
renderTo: myDiv,
height: 180,
width: 900,
title: 'List of Packages'
});
I get this error :
Uncaught TypeError: Cannot read property 'dom' of null
Which is found at line 28211 in ext-all-debug. Code looks like this :
if (!me.container) {
me.container = Ext.get(me.el.dom.parentNode);
}
Anyone know what the issue is when i want to add a grid?
Also my index.html looks like this :
<script>
Ext.require([
'Ext.data.*',
'Ext.grid.*',
'Ext.tree.*'
]);
Ext.onReady (function () {
//application is built in here
});
</script>
Here's a fiddle :
https://fiddle.sencha.com/#fiddle/693
If I render to Ext.getBody() it works fine, but if i render to my own myDiv object it seems to have problems.
My solution to my question..
I am confusing renderTo with add.
I should create a panel, and use renderTo to put it somewhere on the DOM, and then later I can create a grid and then the panel can 'add' it.
Ext.onReady (function () {
var myDiv = Ext.create('Ext.Panel',{
renderTo:Ext.getBody(),
})
var myData = [
['Apple',29.89],
['Ext',83.81]
];
var ds = new Ext.data.SimpleStore({
fields: [
{name: 'company'},
{name: 'price'}
]
});
ds.loadData(myData);
var grid = new Ext.grid.GridPanel({
store: ds,
columns: [
{header: "Company", width: 120, dataIndex: 'company'},
{header: "Price", width: 90, dataIndex: 'price'}
],
height: 180,
width: 900,
title: 'List of Packages'
});
myDiv.add(grid);
//document.body.appendChild(myDiv);
});

I have a custom component (a grid), that i want to add to a panel, and then have a strip of components on the top.
All the examples on the internet look like this :
var extPanel = Ext.create('Ext.form.Panel', {
items: [{
fieldLabel: 'Send To',
name: 'to',
anchor:'100%'
},{
fieldLabel: 'Subject',
name: 'subject',
anchor: '100%'
},
I want to add my own custom component, called myGrid. I would expect some kind property called component passing in the items, but I have no idea, because there is no documentation on what this 'items' array can be.
var extPanel = Ext.create('Ext.form.Panel', {
items: [{
component : myGrid
anchor:'100%' // anchor width by percentage
}
You can use xtype to explicitly create already defined components.You can refer this fiddle : Demo
I solved my problem by nesting items in items, like so :
this.packageGrid = Ext.create('js.grid.PackageGrid', {
xtype: 'packageGrid',
// title: 'Packages',
width: '100%'
});
var extPanel = Ext.create('Ext.Panel', {
layout:'border',
bodyPadding: 5,
items:[{
region:'center'
,layout:'fit'
,border:false,
items:[
this.packageGrid
]
},{
region:'north'
,layout:'fit'
,border:false
,height:50
,collapsible:false,
items:[
button
]
}],
width: '979px',
height: '400px'
});
I have the following EditorGridPanel on extJS:
http://jsfiddle.net/VDFsq/1/
Ext.onReady(function () {
var myData = [[ '<SPAN STYLE=\"text-align:Left;font-family:Segoe UI;font-style:normal;font-weight:normal;font-size:12;color:#000000;\"><P STYLE=\"font-family:Arial;font-size:16;margin:0 0 0 0;\"><SPAN><SPAN>HTML </SPAN></SPAN><SPAN STYLE=\"font-weight:bold;color:#FF0000;\"><SPAN>FORMAT</SPAN></SPAN><SPAN><SPAN> TEST<BR />TEST</SPAN></SPAN></P></SPAN>', "lisa#simpsons.com", "555-111-1224"],
[ 'Bart', "bart#simpsons.com", "555-222-1234"],
[ 'Homer', "home#simpsons.com", "555-222-1244"],
[ 'Marge', "marge#simpsons.com", "555-222-1254"]];
var store = new Ext.data.SimpleStore({
fields:[ {
name: 'name'
},
{
name: 'email'
},
{
name: 'phone'
}],
data: myData
});
var grid = new Ext.grid.EditorGridPanel({
renderTo: 'grid-container',
columns:[ {
header: 'Name',
dataIndex: 'name',
width:200
}
],
store: store,
frame: true,
height: 240,
width: 500,
enableColumnMove :false,
stripeRows: true,
enableHdMenu: false,
border: true,
autoScroll:true,
clicksToEdit: true,
title: 'HTML in Grid Cell',
iconCls: 'icon-grid',
sm: new Ext.grid.RowSelectionModel({
singleSelect: true
})
});
grid.on({
celldblclick: function() {alert(1);}
});
});
the problem is, when the gridCell contains HTML data (which is my situation) when you double click on the cell with html the grid does not fire the event celldblclick.
in my application I need to display that kind of html in the grid.
how can fix this problem? anyway to bubble the event from the html to the grid?
Thanks
It seems that there is some limits to dom tree deep inside your structure. I think it is not good idea to put html into grid - if you can unify it structure - may be templates would be more useful.
Try this instead of your HTML:
"<div ondblclick=\"alert('1!')\">1<div ondblclick=\"alert('2!')\">2<div ondblclick=\"alert('3!')\">3<div ondblclick=\"alert('4!')\">4</div>3</div>2</div>1</div>"
Event inheritance works fine in this HTML, but works only 2 levels deep in your EXt example.
NOTE: if you try
grid.on('rowdblclick', function(eventGrid, rowIndex, e) {
console.log('double click');
}, this);
you will not get problem (but, obviously, you can dblclick only rows in this way)
I am new to Ext JS and I need to update an old app. The EditorGridPanel has an 'ADD' button and it works fine. However, I need to add a 'DELETE' button that deletes the row from the grid. Here is the code to the grid. Thanks for your help.
/*==== INVOICE DATA START =======================================================*/
var iLineItemCM = new Ext.grid.ColumnModel([
{id:'i_line_item_name', header: "Line Item Name", dataIndex: 'i_line_item_name', width: 280,

,{header: "Amount", dataIndex: 'i_line_item_amt', width: 80, align: 'right', renderer: 'usMoney',

///////////////////
From the docs for Cell Selection Model: http://docs.sencha.com/ext-js/2-3/#!/api/Ext.grid.CellSelectionModel
The cell model is specified as default.
getSelectedCell( ) : Array
Returns the currently selected cell's row and column indexes as an array (e.g., [0, 0]).
So... something like
{ text: 'Remove',
tooltip:'Remove the selected item',
handler: function(){
iLineItemGrid.stopEditing();
var r = iLineItemGrid.getSelectionModel().getSelectedCell();
iLineItemStore.removeAt(r[1]); } }
I am new to ExtJs. I need to create an entry form in 2 columns using column layout.
My code is as follows:
Ext.onReady(function(){
var patientForm = new Ext.FormPanel({
renderTo: "patientCreation",
frame: true,
title: 'Search Criteria',
labelAlign: 'left',
labelStyle: 'font-weight:bold;',
labelWidth: 85,
width: 900,
items: [
{
layout:'column',
items:[
{ // column #1
columnWidth: .33,
layout: 'form',
items: [
{ xtype: 'textfield',
fieldLabel: 'FirstName',
name: 'firstName',
vtype : 'alpha',
allowBlank:false
},{
xtype: 'textfield',
fieldLabel: 'MiddleName',
name: 'middleName',
vtype : 'alpha'
}
] // close items for first column
}]
}]
});
var win = new Ext.Window({
layout:'form',
closable: false,
resizable: false,
plain: true,
border: false,
items: [patientForm]
});
win.show();
});
But when I run the code, I got h is undefined error. How to design a form in column layout? Is there any procedure, steps or links which give a clear idea?
I have run the same code with ExtJs 3.2.2 and got a similar error. But when I removed renderTo: "patientCreation"
code worked:
That part is not necessary 'cause you are placing the form in a the window.
I do not know anything about ExtJS 3. If you are using ExtJS 4, then you have specified layout config at wrong place. You have specified it inside items config, it should not be inside items config.
Layout can be specified as follows in ExtJS 4:
Ext.define('your_domain_name.viewName', {
extend : 'Ext.panel.Panel',
alias : 'widget.any_name_you_want',
layout : 'column',
initComponent : function() {
this.items = [
// all items inside form/panel will go here
];
this.callParent(arguments);
}
});
You can get sample code about all the panels here
try applying renderTo config to window instead of form
check example
I using Ext JS 2.3.0 and have a GridPanel that looks like this:
I want to expand the width of the column such that the scroll bar is pushed over the extreme right of the panel, thus eliminating the empty space to the right of the scroll bar.
The relevant code is shown below:
var colModel = new Ext.grid.ColumnModel([
{
id: 'name',
header: locale['dialogSearch.column.name'],
sortable: true,
dataIndex: 'name'
}
]);
var selModel = new Ext.grid.RowSelectionModel({singleSelect: false});
this._searchResultsPanel = new Ext.grid.GridPanel({
title: locale['dialogSearch.results.name'],
height: 400,
layout: 'fit',
stripeRows: true,
autoExpandColumn: 'name',
store: this._searchResultsStore,
view: new Ext.grid.GridView(),
colModel: colModel,
selModel: selModel,
hidden: true,
buttonAlign: 'center',
buttons: [
{
text: locale["dialogSearch.button.add"],
width: 50,
handler: function () {
}
},
{
text: locale["dialogSearch.button.cancel"],
width: 50,
handler: function () {
entitySearchWindow.close();
}
}
]
});
You should use the forceFit config for the grid view:
this._searchResultsPanel = new Ext.grid.GridPanel({
title: locale['dialogSearch.results.name'],
height: 400,
layout: 'fit',
viewConfig: {
forceFit: true
}, ....
I'm not sure if this isn't redundant so you can remove this part view: new Ext.grid.GridView(),
The problem is not the column but the grid itself which does not stretch to fill the window body completely.
Put the layout: 'fit' property onto the window config instead of onto the grid config (where it needs to be removed). You should also remove the height property because the grid height will determined by the window's size.
Add
flex: 1,
to one of the the columns config
