I am having big troubles with data bindings in ExtJs5. I still can't understand why the field label can't be binded to the view-controller as there is a setFieldLabel() function?
{
xtype: 'combobox',
store: 'genderStore',
queryMode: 'local',
displayField: 'label',
valueField: 'gender',
labelAlign: 'top',
bind:{
value:'{scrape}',
fieldLabel:'{myLabel}'
}
}
formulas: {
myLabel:function(get){
return get('widgetSettings').properties.keyDim.dimensionName;
},
scrape:function(get){
return 0;
},
The value gets populated, but the fieldLabel - not.
Thanks!

I am trying to create two combo boxes. The first one shows the country names and the second one shows provinces/states. The idea is to filter the second combo based the selection on first one and put the value of 'VisitingCountryProvince' as the default selection.
The problem with the below code is, it is not selecting the default value based on the first combo box. If I remove the bind filter, the second combo box shows the correct value of 'VisitingCountryProvince'.
Any idea?
{
xtype: 'fieldset',
title: 'Visiting Country',
layout: 'anchor',
anchor: '-10',
collapsible: false,
defaults: {
xtype: 'combo',
labelStyle: 'font-weight: bold;',
flex: 1,
anchor: '0',
editable: false,
forceSelection: true,
allowBlank: false,
emptyText: 'Select...',
queryMode: 'local',
},
items: [{
name: 'VisitingCountry',
fieldLabel: 'Main',
reference: 'visitingCountryFieldRef',
publishes: 'value',
store: {
type: 'arraydropdownstore'
},
valueField: 'value',
displayField: 'value'
}, {
name: 'VisitingCountryProvince',
fieldLabel: 'Sub',
store: {
type: 'array',
fields: ['value', 'countryName']
},
bind: {
filters: {
property: 'countryName',
value: '{visitingCountryFieldRef.value}'
}
},
valueField: 'value',
displayField: 'value'
}]
},
The closest answer to the issue I could find is in here, How to use combo "publishes" value & bindings to filter store on another combo
I just figured out that, I can do either filter or select a default value, not both. How do I filter and bind a default value from the filtered list?
You need to write your logic of filtering the values of second combo store in the "select" event handler of the first combo box.
{
name: 'VisitingCountry',
fieldLabel: 'Main',
reference: 'visitingCountryFieldRef',
publishes: 'value',
store: {
type: 'arraydropdownstore'
},
valueField: 'value',
displayField: 'value',
listeners:{
select:function(){
//Access the second[bound to second combobox]store and apply the
//filter, Also there are arguments for select event handler, for this
//Please refer docs.sencha.com for extjs version you are using.
}
}
}
I have ExtJs combo drop down list. I want to two-color(odd as red and even as green)row list when combo is span
Note: single row has multi(more than one line) lines
Is this possible with ExtJS 4.2? if yes how can i do that.
{ xtype: 'combobox',
id: 'mycbo',
itemId: 'mycbo',
fieldLabel: 'Name',
name: 'id',
tabIndex: 5,
allowBlank: false,
displayField: 'NAME',
forceSelection: true,
queryMode: 'local',
store: 'STORE',
valueField: 'ID'
},
You should use listConfig config to change behaviour of combobox picker. (For more information: http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.form.field.ComboBox-cfg-listConfig)
In snippet below I'm setting class 'odd' and 'even' to each option in the combobox. Then I can style it with CSS.
Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose State',
store: states,
queryMode: 'local',
displayField: 'name',
valueField: 'abbr',
listConfig: {
getInnerTpl: function(displayField) {
return '<tpl if="xindex%2==0"><div class="odd"></tpl><tpl if="xindex%2==1"><div class="even"></tpl> {' + displayField + '} </div>';
}
},
renderTo: Ext.getBody()
});
Take a look at the Custom Item Templates example here - http://docs.sencha.com/extjs/4.2.0/#!/example/form/combos.html and look at the source code and how the listConfig is used.
You should be able to use this approach for achieving custom styling of the list items that appear
I want to use a combobox which receives the preselected value from a data binding and also the possible options from a data binding of the same store.
The panel items configuration looks like this:
{
xtype: 'combobox',
name: 'language_default',
fieldLabel: 'Default Language',
multiSelect: false,
displayField: 'title',
valueField: 'language_id',
queryMode: 'local',
bind: {
value: '{database.language_default}',
store: '{database.languages}'
}
}
If I use this configuration, the store of the combobox is invalid and unuseable.
Is it possible to bind the selected option and also the available options of a combobox?
Upgrade to ExtJs 5.0.1 and you can use selection binding
{
xtype: 'combobox',
name: 'language_default',
fieldLabel: 'Default Language',
multiSelect: false,
displayField: 'title',
valueField: 'language_id',
queryMode: 'local',
bind: {
value: '{database.language_id}',
selection: '{database.language_default}',
store: '{database.languages}'
}
}
I have 2 combos, I want to force to select the first combo (employer combo), after it's selected then the combo 2 (employee combo) is enable.
ExtJS 4.2.1
The code of the combos is:
{
xtype: 'combobox',
store: Ext.create('SoftHuman.store.catalog.Employer', {
autoLoad: true
}),
displayField: 'Description',
valueField: 'EmployerId',
fieldLabel: 'Company',
name: 'EmployerId',
queryMode: 'local',
allowBlank: true
}, {
xtype: 'combobox',
anchor: '100%',
store: Ext.create('SoftHuman.store.employee.EmployeeCombo'),
displayField: 'FullName',
valueField: 'EmployeeId',
queryMode: 'remote',
fieldLabel: 'Employee',
editable: true,
hideTrigger: true,
queryParam: 'searchStr',
name: 'EmployeeId',
allowBlank: true,
listConfig: {
loadingText: 'Searching...',
// Custom rendering template for each item
getInnerTpl: function () {
return '<b>{EmployeeNumber}</b> / {FullName}';
}
}
},
Right now my remote combo employee combo send into the query param "searchStr" that is the string typed in the combo. I need to pass also the selection from combo 1 (employer combo).
How can I achieve this? Thanks.
use something like this.
Ext.ComponentQuery.query('EmployerId').value
Ext.getCmp('EmployerId').value
var empValue = getComponent('EmployerId').value
if .value not work then try getValue() method.
Hope this helps.
in your second component(EmployeeId) add configuration disabled:true on load.
then add afterrender listener to the first one. and then set the other combo available.
Then do this............................................................................
{
xtype: 'combobox',
store: Ext.create('SoftHuman.store.catalog.Employer', {
autoLoad: true
}),
displayField: 'Description',
valueField: 'EmployerId',
fieldLabel: 'Company',
name: 'EmployerId',
queryMode: 'local',
allowBlank: true
listeners: { <---------------------here
select: function(combo, selection) {
if (combo.getValue() != undefined) {
Ext.ComponentQuery.query('EmployeeId').setDisabled(false)
} <----------------------------- to here
}, {
xtype: 'combobox',
anchor: '100%',
store: Ext.create('SoftHuman.store.employee.EmployeeCombo'),
displayField: 'FullName',
valueField: 'EmployeeId',
queryMode: 'remote',
fieldLabel: 'Employee',
editable: true,
disabled:true, <------------add this
hideTrigger: true,
queryParam: 'searchStr',
name: 'EmployeeId',
allowBlank: true,
listConfig: {
loadingText: 'Searching...',
// Custom rendering template for each item
getInnerTpl: function () {
return '<b>{EmployeeNumber}</b> / {FullName}';
}
}
},
Hope this helps :)
I'm setting the value of a combobox using combo.setValue(value) passing an id that is linked to a displayField. The problem is that I want to show the displayField not the id, it seems like extjs does not make the conversion.
{
xtype: 'combobox',
fieldLabel: 'Categoria',
name: 'categoria',
labelAlign: 'top',
allowBlank: false,
blankText: 'Campo obbligatorio',
typeAhead: true,
displayField: 'categoria',
valueField: 'id',
store: comboCategoriaStore,
columnWidth: .2,
margin: 5,
listeners: {
select: {
fn: me.onFieldBlur,
scope: me
}
}
}
