I update editor grid cell value (textfield) in controller and try to sync store but the store does not update the updated row. I think the store couldn't recognize the cell has been updated.
in controller, I did like this,
this.getMyGrid().store.each(function (item) {
if (!item.data.testField) {
item.set('testFeild', "UPDATED");
item.commit();
}
});
this.getMyGrid().store.sync();
then, it update cell value as well, but it couldn't sync();
anybody know, what I am doing wrong, please advice me.
Thanks
Without item.commit();, it works fine :)

Is it possible somehow to update Vuetify v-combobox items as the user is typing? I want to change the list of available items depending on what the users started typing, to create an address input with suggestions from a geolocation API.
This is what I tried: #update:search-input='fetchAddresses'
And in fetchAddresses: this.items = newListOfItems
However, while #update:search-input fires as expected, the combobox list will only be updated after losing focus. Can I somehow trigger it to be updated? (This may very well be an X/Y problem, so any hints about other approaches are welcome)
My current, ugly, hack is to force the whole combobox component to re-render with the current value set, and then refocus on it. (There is an activateMenu() method on the combobox that I could use to make sure the list reopened:
this.$nextTick(() => {
if (this.$refs.addressCombobox) {
this.$refs.addressCombobox.focus()
this.$refs.addressCombobox.activateMenu()
}
})
I'm using Vue 2.
In my case no-filter solved this problem
<v-combobox no-filter ... >
Please help. I have this code. I have a feeling that v-for caches (or wrongly work with it) my data array. Newly added objects (with "Add" button) are edited like the same. Try to add some rows and put some text or change a checkbox and you will see.
// Update this fn to:
addMessenger() {
this.data.profile.vsAppMessengers.push({...this.data.profile.messengerTemplate});
},
Issue was: the object is copied by reference. To read more: https://codeburst.io/explaining-value-vs-reference-in-javascript-647a975e12a0

I have problem in rendering a template
When a new data has been added, it won't go to the process of v-if even if the condition is both TRUE.
Can some please explain why?
I have provided some screenshot below to explain further my issue
This first image was my template for displaying the products, you will notice the add, update and remove in here.
The second image shows that I'm trying to add a new product
The third image shows that I have successfully added the new product. The problem is, the action button "update" is triggered but won't take any effect.
The image above shows that the update button works with the past data, but not with the new one.
This last image will prove that the button has been triggered. I've added a console.log to display the following upon clicking the update button.
INDEX of the row, which is [0].
The typeOf the variable 'isUpdate' [boolean].
The value of 'isUpdate' [True, False]
and the productID which is [151]
Any idea why it hasn't been triggered, or any idea how to debugged this?
If you want to see the code. I can provide it, just tell me which part are you looking for. As I don't have any idea which part has the error.
Thank you in advance.
Updated
AS per Amresh Venugopal Request
Here is the v-if in the template
<tr v-if='product.id > 0 && product.isUpdate' class='table-inputs'>
And the updatebtn function
canUpdate: function(data) {
console.log(data.pindex);
this.products[data.pindex].isUpdate = !this.products[data.pindex].isUpdate;
console.log(typeof this.products[data.pindex].isUpdate);
console.log(this.products[data.pindex].isUpdate);
console.log(this.products[data.pindex].id);
}
I only set the isUpdate value to 'true' if 'false', and viceversa.
The productID is added after the ajax save function.
I figure it out!
When I push the data in this.products, I didn't include the 'isUpdate' field.
Got it working now.
I wrapped my gridview with Pjax widget like this
\yii\widgets\Pjax::begin();
gridview
\yii\widgets\Pjax::end();
in order to make the gridview make ajax request when I click on each pagination.
I also use ['class' => 'yii\grid\CheckboxColumn'], in column as well.
and I find that when I'm on first pagination I checked some rows and then go to second page and check some rows but when I go back to first page what I've checked is gone.
My question is how can I keep all checkedrow for all pagination
With current conditions (Pjax, multiple pages, yii\grid\CheckboxColumn) it's impossible because of the way it works.
When you click on the pagination links all GridView html content is replaced by new one that comes from the AJAX response.
So obviously all selected checkboxes on the previous page are gone.
Few possible ways to solve that:
1) Write custom javascript and server side logic.
As one of the options, you can send AJAX request to server with parameter meaning that user has chosen to select all data for the bulk delete operation (or use separate controller action for bulk deletion). In this case actually we don't need to get the selected data from user, because we can simply get them from database (credits - Seng).
2) Increase number of displayed rows per page.
3) Use infinite scroll extension, for example this.
4) Break desired action in several iterations:
select needed rows on first page, do action (for example, delete).
repeat this again for other pages.
You can get selected rows like that:
$('#your-grid-view').yiiGridView('getSelectedRows');
[infinite scroll] : http://kop.github.io/yii2-scroll-pager/ will work good if you do not have any pjax filters. If you have filters also in play, do not use this plugin as it does not support pjax filters with it. For rest of the applications it is perfect to use.
Update1 : it seems to be straight forward than expected, here is the how I accomplished it
Add following lines to the checkbox column
'checkboxOptions' => function($data){
return ['id' => $data->id, 'onClick' => 'selectedRow(this)'];
}
Now add following JS to the common js file you will have in your project of the page where this datagrid resides
var selectedItems=[]; //global variable
/**
* Store the value of the selected row or delete it if it is unselected
*
* #param {checkbox} ele
*/
function selectedRow(ele){
if($(ele).is(':checked')) {
//push the element
if(!selectedItems.includes($(ele).attr('id'))) {
selectedItems.push($(ele).attr('id'));
}
} else {
//pop the element
if(selectedItems.includes($(ele).attr('id'))) {
selectedItems.pop($(ele).attr('id'));
}
}
}
Above function will store the selected row ids in the global variable array
Now add following lines to pjax:end event handler
$(document).on('pjax:end', function () {
//Select the already selected items on the grid view
if(!empty(selectedItems)){
$.each(selectedItems, function (index,value) {
$("#"+value).attr('checked',true);
});
}
});
Hope it helps.
I just solved this problem and it works properly with Pjax.
You may use my CheckboxColumn. I hope this can help. The checked items are recorded with cookies.
You can read the part with //add by hezll to understand how to fix it, because I didn't provide a complete general one.
Hope it works for you.

I have two related ComboBoxes ( continents, and countries ). When the continents ComboBox changes I request a XML from a certain URL. When I receive that XML i change the DataProvider for the countries ComboBox, like this:
public function displayCountryArray( items:XMLList ):void
{
this.resellersCountryLoader.alpha = 0;
this.resellersCountry.dataProvider = items;
this.resellersCountry.dispatchEvent( new ListEvent( ListEvent.CHANGE ) );
}
I dispatch the ListEvent.CHANGE because I use it to change another ComboBox so please ignore that (and the 1st line ).
So, my problem is this: I select "ASIA" from the first continents, then the combobox DATA get's updated ( I can see that because the first ITEM is an item with the label '23 countries' ). I click the combo then I can see the countries.
NOW, I select "Africa", the first item is displayed, with the ComboBox being closed, then when I click it, the countries are still the ones from Asia. Anyway, if I click an Item in the list, then the list updates correctly, and also, it has the correct info ( as I said it affects other ComboBoxes ). SO the only problem is that the display list does not get updated.
In this function I tried these approaches
Converting XMLList to XMLCollection and even ArrayCollection
Adding this.resellersCountry.invalidateDisplayList();
Triggering events like DATA_CHANGE and UPDATE_COMPLETE
I know they don't make much sense, but I got a little desperate.
Please note that when I used 3.0.0 SDK this did not happen.
Sorry if I'm stupid, but the flex events are killing me.
Setting the dataprovider of the comboBox' dropdown seems to fix this problem.
this.resellersCountry.dataProvider = items;
this.resellersCountry.dropdown.dataProvider = items;
this.resellersCountry.dropdown.dataProvider = items;
works (Flex SDK 3.5)
Hope this bug fixed in 4.0
In addition to Christophe´s answer:
When you are using data binding in your ComboBox you need to use the BindingUtils to set the dropdown´s dataprovider:
MXML:
<mx:ComboBox id="cb_fontFamily"
width="100%"
dataProvider="{ model.fontFamilies }" />
Script:
private function init():void
{
BindingUtils.bindSetter(updateFontFamilies, model, "fontFamilies");
}
private function updateFontFamilies(fontFamilies:ArrayCollection):void
{
if (cb_fontFamily != null) cb_fontFamily.dropdown.dataProvider = fontFamilies;
}
Thanks to Christophe for pointing in the right direction.
Another workaround, outlined in an Adobe Community forum post, is to avoid re-assigning a different ArrayCollection object to the ComboBox, and instead re-using (and re-populating) the original one instead:
items.removeAll();
for each (var item:* in newItems)
{
items.addItem(item);
}
