ExtJS prevent resizecolumn event while loading columns - javascript

I'm working on an ExtJS 6.2 project. I need to perform some operations when the columns in a grid a resized. I think the correct event to do so is columnresize. The problem is, since the columns are being loaded from a database dynamically, this event is fired every time a new column is added to the grid, and I would like to prevent it. I mean, I need this event to be fired only when every column is loaded.
I've tried to set a flag (named lFirstInit) that would be false once the columns are loaded form database, but the columnresize event keeps on being fired from the start.
How could I approach this, please? Thanks.
View:
Ext.define('App.view.TMainBrowseGrid', {
extend: 'Ext.grid.Panel',
alias: 'widget.TMainBrowseGrid',
requires: [
'App.view.TMainBrowseGridViewModel',
'App.view.override.TMainBrowseGrid',
'Ext.view.Table',
'Ext.grid.column.RowNumberer',
'App.view.TMainBrowseGridViewController'
],
controller: 'TMainBrowseGrid',
config: {
oParent: null,
cBrwName: '',
cCodForm: ''
},
viewModel: {
type: 'TMainBrowseGrid'
},
flex: 1,
columns: [
{
xtype: 'rownumberer',
itemId: 'oColRowNum'
}
],
listeners: {
columnresize: 'onGridpanelColumnResize',
}
});
Controller
Ext.define('App.view.TMainBrowseGridViewController', {
extend: 'Ext.app.ViewController',
alias: 'controller.TMainBrowseGrid',
onGridpanelColumnResize: function (component, column, width, eOpts) {
// THINGS TO DO...
}
});

We have finally discarded the 'columnresize' approach. We thought it is more reliable performing thos operations when clicking on a 'Close' button. However, I would like to thank you for your suggestions, especially the person who posted the answer below, and later removed it before I could mark it as the chosen answer. This was the code he/she posted:
Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
fields: ['name', 'email', 'phone'],
data: [{
name: 'Lisa',
email: 'lisa#simpsons.com',
phone: '555-111-1224'

}]
});
Ext.create('Ext.grid.Panel', {

}, {
text: 'Phone',
dataIndex: 'phone'
}],
height: 200,
width: 400,
renderTo: Ext.getBody(),
listeners: {
columnresize: function(ct, column, width, eOpts){
if(ct.containsFocus){// It will true when we resize column.
alert('resize');
console.log(`${column.text} Column resized`);
}
}
}
});

Adding new property to Ext JS Grid column

Can I add a new unique property to gridcolumn in Ext JS? I want to use that property in some other place
{
xtype: 'gridcolumn',
dataIndex: 'startupPercent',
sortable: true,
'property': 'value', // so that i can access it later
text: 'StartUp%'
}
Can I add a new unique property to gridcolumn
Yes you can and you use that property other place.
In this FIDDLE, I have created a demo provide a custom config and get on header click. I hope this will help/guide you to achieve your requirement.

Dynamically changing property field in ExtJs Grid

I am using a grid with a checkbox and a combobox. Right now I am trying to find a way to make the combobox multi select if the checkbox is checked in roweditor.
var pEditing =
Ext.create('Ext.grid.plugin.RowEditing',
{
clicksToMoveEditor: 2,
errorSummary: false,
autoCancel: false,
listeners:
{
change: function (newValue, oldValue, eOpts)
{
if (newValue.value == true)
{
this.down().down('grid').queryById('comboboxColumn').multiSelect = true;
}
else
{
this.down().down('grid').queryById('comboboxColumn').multiSelect = false;
}
console.log("Checkbox Change Debug");
}
}
});
Grid creation code :
{
renderer: renderCheckbox,
itemId: 'checkboxColumn',
header: 'Checkbox',
width: 100,
sortable: false,
dataIndex: 'ddCheckbox',
editor: {
xtype: 'checkbox',
cls: 'x-grid-checkheader-editor',
listeners:{
change: function (newValue, oldValue, eOpts) {
pEditing.fireEvent('change',newValue, oldValue, eOpts);
}
},
},
},
{
header: 'Speed',
dataIndex: 'ddSpeed',
itemId: 'comboBoxColumn',
width: 125,
editor:
{
xtype: 'combo',
editable: false,
multiSelect: false,
store:
[
['1', '1'],
['2', '2'],
['3', '3'],
['4', '4'],
['5', '5']
]
}
}
Right now the event is firing off and I can see the debug message printed to the log. However the multiselect property is not persisting after the event is fired. Is there any easy way to change the property of this combobox in the row? For example, if there are 3 rows in the grid, row one can have the checkbox checked, and multiple values selected while row two has the checkbox unchecked and only one selection can be made? I know I can find the index of the checkbox selected by using in the change function.
this.down().down('grid').getSelectionModel().getSelection()[0].getData()
Thanks
"multiselect" property is not persisting because, your below code is not yet reach till combo box control.
this.down().down('grid').queryById('comboboxColumn').multiSelect = true;
As per your code, combo box control is under 'comboBoxColumn' item. So specify "itemID" for combo box like
xtype: 'combo',
editable: false,
multiSelect: false,
itemId: 'comboBoxItems',
store:[....]
Then, try below code
this.down().down('grid').queryById('comboboxColumn').queryById('comboBoxItems').multiSelect = true;
As you using RowEditing plugin
In checkbox on value change event you will get 4 parameters change:function(field, newValue, oldValue, eOpts)
1) Usign field parameter you will get your selected row(roweditor) like this field.up().
2) Using this roweditor you can use roweditor.down() method and get your combo.
3) After that getting your component(combo) and using second parameter newValue you can set multiSelect like combo.multiSelect = newValue
Here is I have created an sencha fiddle demo.
Hope this will help you to achieve your solution or requirement

Dynamically set flex configuration for columns

Let's assume I have a window with a grid inside.
I code this via ExtJS, version 5.1.3.
This grid has four columns and the last one has the property flex:1.
Perfect, everything is aligned.
Now I have the possibility to hide the last column. As the other columns do not have the property flex, the grid is cut inside the window.
The window looks then similar to the last screenshot in this link.
Now my question: Is it somehow possible to define kind of a temporary flex property if no column with flex is available and then reset as soon as it is again?
You can specify forceFit : true configuration in grid object.
Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
fields: ['name', 'email', 'phone'],
data: [{
name: 'Lisa',
email: 'lisa#simpsons.com',
phone: '555-111-1224'
}, {
name: 'Bart',
email: 'bart#simpsons.com',
phone: '555-222-1234'
}, {
name: 'Homer',
email: 'homer#simpsons.com',
phone: '555-222-1244'
}, {
name: 'Marge',
email: 'marge#simpsons.com',
phone: '555-222-1254'
}]
});
Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
forceFit : true,
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [{
text: 'Name',
dataIndex: 'name'
}, {
text: 'Email',
dataIndex: 'email',
flex: 1
}, {
text: 'Phone',
dataIndex: 'phone'
}],

Ext JS components within an expanded row

Simple question here: I have a working grid with expanding rows within my Ext JS application. Boom.
Currently I have html elements inside of my expanded row (it's just one big div), but that seems to be all the expanded row is capable of displaying.
Is there anyway to render Ext components inside of my expanded rows?
Cheers mates, upvotes await!
You can just render components into the row expanders element.
var grid = Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
plugins: {
ptype: 'rowexpander',
rowBodyTpl : [
'<div class="row-expander-ct"></div>'
]
},
store: {
fields:['name', 'email', 'phone'],
data: [
{ 'name': 'Lisa', "email":"lisa#simpsons.com", "phone":"555-111-1224" },
{ 'name': 'Bart', "email":"bart#simpsons.com", "phone":"555-222-1234" },
{ 'name': 'Homer', "email":"home#simpsons.com", "phone":"555-222-1244" },
{ 'name': 'Marge', "email":"marge#simpsons.com", "phone":"555-222-1254" }
]
},
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' }
],
height: 300,
width: 400,
renderTo: Ext.getBody()
});
grid.store.on({
// Delay the execution of the listener because the grid view will also
// react to this event, and we want the rows to be rendered before we
// modify them...
delay: 1,
load: function() {
Ext.each(grid.el.query('.row-expander-ct'), function(ct) {
Ext.widget('textfield', {
renderTo: ct
,fieldLabel: "Label"
,width: '100%'
});
});
}
});
grid.store.load();

Grid Return on Editable Field in Rally SDK2

I have a grid with a column like this:
{ text: 'Name', dataIndex: 'Name', editor: 'rallytextfield', flex: 2.5, sortable: false },
When I fill in information in the text field and then click somewhere else, the data is saved; however, when I hit return or tab like in a Custom Grid, nothing happens. What can I configure to allow me to return away from this field and so get the value to save without clicking?
EDITED: It turns out that it's to do with adding checkboxes. If I add a selModel, the return doesn't work. If I take it away, the return works! Here's the full app:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
var store = Ext.create('Rally.data.custom.Store', {
data:[
{ 'name': 'Lisa', "email":"lisa#simpsons.com", "phone":"555-111-1224" },
{ 'name': 'Bart', "email":"bart#simpsons.com", "phone":"555-222-1234" },
{ 'name': 'Homer', "email":"home#simpsons.com", "phone":"555-222-1244" },
{ 'name': 'Marge', "email":"marge#simpsons.com", "phone":"555-222-1254" }
]
});
this.add( Ext.create('Rally.ui.grid.Grid', {
title: 'Simpsons',
store: store,
columnCfgs: [
{ text: 'Name', dataIndex: 'name', editor: 'rallytextfield' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone', editor: 'textfield' }
],
height: 200,
width: 400,
selType: 'checkboxmodel',
selModel: {
injectCheckbox: 1,
mode: 'SIMPLE'
}
}) );
}
});
Commenting out selType & selModel and I can hit return to go from one row to the next, but with the selType & selModel in there, no return but tab does work.
The Return/Tab inline edit navigation should be built-in without any additional configuration. When I try to repro the issue the first thing I run into is this:
App works as desired in debug mode but crashes in Rally environment
That may be the root cause since the app is likely just refreshing once the field is edited.
My working column config on my gridConfig looks like this:
columnCfgs: [
'FormattedID',
{
text: 'Name',
dataIndex: 'Name',
editor: 'rallytextfield',
flex: 2.5,
sortable: false
},
'Owner'
],
