[Filter][DataGrid] how to create datagrid with pre-select filters dynamically?

I’d like to pass parameter from request to fitlers of dataGrid like this:

filters: columns: ... name: data_name: g.name ... default: name: { value: _parameters.name_filter } # how could i send the 'name_filter' variable to this ? // front-end dataGrid.renderGrid('my-grid', {name_filter: 'someone'})

1 2 3 4 5 6 7 8 9 10 11 12

filters:             columns:                 ...                 name:                     data_name: g.name                     ...             default:                 name: { value: _parameters.name_filter }  # how could i send the 'name_filter' variable to this ? // front-end dataGrid.renderGrid('my-grid', {name_filter: 'someone'})

how could i archive this?

Hi, anhnhoktvn.

To set default value that comes from datagrid parameters, you can create own datagrid listener what will set this value to the filters part.

Hereis listener class:

<?php namespace Acme\Bundle\DemoBundle\Event; use Oro\Bundle\DataGridBundle\Event\BuildBefore; class MyGridListener { /** * @param BuildBefore $event */ public function onBuildBefore(BuildBefore $event) { // here we take the value of name_filter parameter $value = $event->getDatagrid()->getParameters()->get('name_filter'); // take filters block of datagrid configuration $filters = $event->getConfig()->offsetGetByPath('filters'); // add default subblock with values $filters['default'] = [ 'name' => ['value' => $value] ]; // save changes filters block $event->getConfig()->offsetSetByPath('filters', $filters); } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

<?php   namespace Acme\Bundle\DemoBundle\Event;   use Oro\Bundle\DataGridBundle\Event\BuildBefore;   class MyGridListener {     /**      * @param BuildBefore $event      */     public function onBuildBefore(BuildBefore $event)     {         // here we take the value of name_filter parameter         $value = $event->getDatagrid()->getParameters()->get('name_filter');           // take filters block of datagrid configuration         $filters =  $event->getConfig()->offsetGetByPath('filters');           // add default subblock with values         $filters['default'] = [             'name' => ['value' => $value]         ];           // save changes filters block         $event->getConfig()->offsetSetByPath('filters', $filters);     } }

Service definition of this listener:

acme_demo.event.my_grid_listener: class: Acme\Bundle\DemoBundle\Event\MyGridListener tags: - { name: kernel.event_listener, event: oro_datagrid.datagrid.build.before.my-grid, method: onBuildBefore }

1 2 3 4 5 6

acme_demo.event.my_grid_listener:         class: Acme\Bundle\DemoBundle\Event\MyGridListener         tags:             - { name: kernel.event_listener, event: oro_datagrid.datagrid.build.before.my-grid, method: onBuildBefore }

With this example, it’s not necessary to add default block definition in your datagrid.yml file.
