I got grid with columns:
...
columns: [
{
xtype: 'rownumberer'
}, {
xtype: 'checkcolumn',
sortable: false,
header: 'done',
dataIndex: 'status',
flex: 2,
width: 55,
callback: function(success, model) {
this.setRawValue(success); // DOESNT WORK
this.setValue(success); // DOESNT WORK
},
}
...
I would like to change checkbox state to checked or unchecked. Functions setValue() or setRawValue() have no effect for the checkbox - moreover - there are not available for
the widget.
Is there simple function like setChecked(boolean) in extjs for checkcolumn?
It is ridiculous I have instance 'checkcolumn' but I can't find basic function.
I will be glad for any hint. Thank you.

for record in grid store with 'fieldName' checkcolumn write
record.set('fieldName',false)
or
record.set('fieldName',true)
it make field selected/deselected
the most simple way is to do it in the store , you can add a new boolean field in the store with default of true to do that , and later just change that boolean in the store and the grid will be reflected with the changes

I have in my ExtJS 4.2.1 Application a grid with the following editable column:
text: 'Location',
dataIndex: 'LocationId',
width: 140,
renderer: function(value) {
var record = me.store.findRecord('LocationId', value);
return record.get('Description');
},
editor: {
xtype: 'combobox',
typeAhead: true,
triggerAction: 'all',
store: Ext.create('App.store.catalog.Location', {
autoLoad: true
}),
displayField: 'Description',
valueField: 'LocationId',
listConfig: {
width: 250,
loadingText: 'Searching...',
// Custom rendering template for each item
getInnerTpl: function() {
return '<b>{Code}</b><br/>(<span style="font-size:0.8em;">{Description}</span>)';
}
}
}
The combo has a renderer to display the Description of the LocationId selected.
Then, my grid has the feature 'Ext.grid.plugin.CellEditing' so I can edit just that column cell.
The problem that I have is when I press the "Update" button, the combo display value returns to the original it used to have, even if the LocationId in the record has the right value.
This is my code that gets fired when the user press the "Update" button.
me.rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor: 1,
autoCancel: false,
listeners: {
edit: function(editor, e) {
var record = e.record;
me.setLoading('Updating...');
App.util.Ajax.request({
noMask: true,
url: '/api/catalog/UpdateEmployeeLocation',
jsonData: record.getData(),
success: function(response, opts) {
var obj = Ext.decode(response.responseText);
if (obj.success) {
// commit changes (no save just clear the dirty icon)
me.getStore().commitChanges();
}
},
callback: function() {
me.setLoading(false);
}
});
}
}
});
The record is saved correctly in my database but the combo display value is not updated with the description that corresponds to the LocationId. If I reload the store from server again then It shows correctly.
So, there is something wrong with the renderer in my column that is not updating the value after I update my record.
Any clue on how to get around this?
Thanks.
You are setting dataIndex as 'LocationId' but no where you are changing the 'LocationId', you are just changing description and updating it in rendered method. Since there no change in 'LocationId', store doesn't consider it as dirty field and hence rendered function is not getting called. One quick and dirty way could be instead of using 'LocationId', create another field in the model say 'LocationIdchangeTraker'. Use 'LocationIdchangeTraker' instead of 'LocationId' in data index. It doesn't not effect your view because you are changing the value in reneerer function. Now whenever you update the function change the value of 'LocationIdchangeTraker' as shown below.
record.set('LocationIdchangeTraker',Ext.getId());
I have a grid with a Column configured like...
{
...
editor:new Ext.form.DateField({format:'m/d/Y'}),
renderer: function (val){return val ? Ext.util.Format.date(val, 'm/d/Y') : ''}
...
}
It works fine, except that when I click on a cell to edit it, the cell gets blanked out rather than maintaining its existing value until I choose new one. If after clicking the cell I click away from it, the cell is left empty.
Any idea what would cause this?
Thanks
I would have thought you'd want your column defined like this:
columns: [{
xtype: 'datecolumn',
format: 'm/d/Y',
editor: {
xtype: 'datefield'
}
}]
I don't think you need to use a renderer or use create are you are using it in your example
I've had a similar problem, and solved it somewhat with setting allowBlank: false, as below:
...
editor:new Ext.form.DateField({
format:'m/d/Y',
allowBlank: false
}),
...
This should reset the value back to its original value if you click out of the datefield without selecting a new value.
I'm trying to make something that looks like: http://dev.sencha.com/deploy/ext-3.4.0/examples/grid/edit-grid.html
But I want to change Light column:
I want it to contain ids instead of actual values.
I can force combobox to separate values from presentation but not the actual column value (in fact I don't know where to store id-value mapping for column (not just for the editor)):
new Ext.grid.EditorGridPanel({
...
store: new Ext.data.Store ({
...
fields: [
'MagicId',
...
]
})
columns: [
{
header: 'Magic',
dataIndex: 'MagicId',
editor: new Ext.form.ComboBox({
store: new Ext.data.Store({
...
fields: ['id', 'title']}),
valueField: 'id',
displayField: 'title',
editable: 'false'
})
},
...
]
When I select "Magic title" in combobox I get MagicId in my grid anyway. I understand why it's happening but can't make it work the way I need it to work...
I tried to replace all unnecessary code with ... to help you reading.
Thank you for your attention.
Keep the ID field in your grid/store, then use the "renderer" property to display something else. ID-text mapping could be stored in an array or an object:
{
header: 'Magic',
dataIndex: 'MagicId',
renderer: function(value) {
return magicIdValueArray[value];
}
...
}
EDIT:
Since you already have the ID-value mapping in the combo store, I would use that store to fetch the value (it needs to be declared outside the combobox).
renderer: function(value) {
var record = comboStore.findRecord('id', value);
return record.title;
}
I have a combo box which populates its values based on the selection of another combobox.
I have seen examples where the params in the underlying store are changed based on the selection, but what I want to achieve is to change the store itself of the second combo based on the selection on the first combo. This is my code, but it doesn't work. Can someone please help?

var container = filter_to_select.container;
if (index == 0){
filter_to_select.store=leadStatusStore;
filter_to_select.displayField='leadStatusName';
filter_to_select.valueField='leadStatusId';
} else if(index==1) {
filter_to_select.store=leadSourceStore;
filter_to_select.displayField='leadSourceName';
filter_to_select.valueField='leadSourceId';

That is not how its designed to work!! When you set a store in the config, you are binding a store to the combo. You don't change the store, instead you are supposed to change the data when required.
The right way of doing it would be to load the store with correct data from the server. To fetch data, you can pass params that will help the server side code get the set of options you need to load.
You will not want to change the store being used... Simply put, the store is bound to the control as it is instantiated. You can, however, change the URL, and params/baseParams used in any additional POST requests.
Using these params, you can code your service to return different sets of data in your combo box's store.
For the proposed problem you can try below solution :
Use below "listener" snippet for the first "leads_filter_by" combo. It will handle the dynamic store binding / changing for the second combobox.
listeners:{
'select': function(combo,value,index){
var filter_to_select = Ext.getCmp('cmbLeadsFilter');
var container = filter_to_select.container;
if (index == 0){
//filter_to_select.store=leadStatusStore;
filter_to_select.bindStore(leadStatusStore);
filter_to_select.displayField='leadStatusName';
filter_to_select.valueField='leadStatusId';
} else if(index==1) {
//filter_to_select.store=leadSourceStore;
filter_to_select.bindStore(leadSourceStore);
filter_to_select.displayField='leadSourceName';
filter_to_select.valueField='leadSourceId';
}
}
}
Hope this solution will help you.
Thanks & Regards.
I had a similar problem. The second combobox would load the store and display the values, but when I would select a value, it would not actually select. I would click the list item and the combobox value would remain blank.
My research also suggested that it was not recommended to change the store and field mappings on a combobox after initialization so here was my solution:
Create a container in the view that would hold the combobox to give me a reference point to add it back later
Grab a copy of the initial config off of the combobox ( this lets me set my config declaritively in the view and not hard code it into my replace function ... in case I want to add other config properties later)
Apply new store, valueField and displayField to that config
Destroy old combobox
Create new combobox with modified config
Using my reference from step 1, add the new combobox
view:
items: [{
xtype: 'combobox',
name: 'type',
allowBlank: false,
listeners: [{change: 'onTypeCombo'}],
reference: 'typeCombo'
}, { // see controller onTypeCombo for reason this container is necessary.
xtype: 'container',
reference: 'valueComboContainer',
items: [{
xtype: 'combobox',
name: 'value',
allowBlank: false,
forceSelection: true,
reference: 'valueCombo'
}]
}, {
xtype: 'button',
text: 'X',
tooltip: 'Remove this filter',
handler: 'onDeleteButton'
}]
controller:
replaceValueComboBox: function() {
var me = this;
var typeComboSelection = me.lookupReference('typeCombo').selection;
var valueStore = Ext.getStore(typeComboSelection.get('valueStore'));
var config = me.lookupReference('valueCombo').getInitialConfig();
/* These are things that get added along the way that we may also want to purge, but no problems now:
delete config.$initParent;
delete config.childEls;
delete config.publishes;
delete config.triggers;
delete config.twoWayBindable;
*/
config.store = valueStore;
config.valueField = typeComboSelection.get('valueField');
config.displayField = typeComboSelection.get('displayField');
me.lookupReference('valueCombo').destroy();
var vc = Ext.create('Ext.form.field.ComboBox', config);
me.lookupReference('valueComboContainer').add(vc);
},
when trying to populate A ENTIRE GRID using the ajax from a combobox in the select listener when i try to recall or reload the datastore i'm still getting the old values, instead of the new ones. i have to get the new values because according to the parameter selected in the combobox the textfields and the others editor will populate with that json data read from server using ajax, accoding with another combobox that fetch remote data
var cm = new Ext.grid.ColumnModel({
defaults: {
sortable: true
},
columns: [{
id: 'ci',
header: 'Periodo Declarado',
dataIndex: 'ci',
width: 150,
editor: new fm.ComboBox({
typeAhead: true,
triggerAction: 'all',
transform: 'PerDecl',
lazyRender: true,
listClass: 'x-combo-list-small',
mode:'local',
listeners:{
expand: function (combo){
//alert("asd");
},
collapse: function(combo,record,number){
},
select:function(v, params, record){
ds_random_employee_data_active.remove();
var varAnio2=v.getValue();
var ds_random_employee_data_active2=ds_random_employee_data_active;
ds_random_employee_data_active2.load({ params: { anio: varAnio2 } });
Ext.each(ds_random_employee_data_active2.data.items, function(record){
alert(record.data.ut);
});
//setTimeout("tres("+ v +"[]);",1000);
}}
})
}

[SOLVED] THANKS U ALL for say i figure it out after four hours or more the way i did is seemed to bmoeskau but i did read the post of bmoeskau after i've got with the solution
thanks u to all
store.load({params:{anio:varanio},callback:function(){// here comes the loop or another instruction
}})
this is a nice forum chat
That's because it loads asynchronously.
If you (re)load a data store, the call is asynchronous, so any action that relies on the updated data must be done within a callback. You can handle the store's load event to do that. See my answer here for an example.
