I have created one custom module with title & status field attribute in admin grid.

Grid collections in module_test_grid_block.xml

        <arguments>

             <argument name="id" xsi:type="string">testGrid</argument>

             <argument name="dataSource" xsi:type="object">NamespaceModuleModelResourceModeltestCollection</argument>

             <argument name="default_sort" xsi:type="string">id</argument>

             <argument name="default_dir" xsi:type="string">desc</argument>                             

             <argument name="grid_url" xsi:type="url" path="*/*/grid"><param name="_current">1</param></argument>

         </arguments>

I want to show the data which are enabled. Have any option to add default filter in admin grid collections?

EDIT

    <block class="NamespaceModuleBlockAdminhtmlTestGrid" name="namespace_module_test.grid" as="grid">

       <arguments>

             <argument name="id" xsi:type="string">testGrid</argument>

             <argument name="dataSource" xsi:type="object">NamespaceModuleModelResourceModeltestCollection</argument>

             <argument name="default_sort" xsi:type="string">id</argument>

             <argument name="default_dir" xsi:type="string">desc</argument>                             

             <argument name="grid_url" xsi:type="url" path="*/*/grid"><param name="_current">1</param></argument>

             <argument name="default_filter" xsi:type="array">

                  <item name="status" xsi:type="string">1</item>

             </argument>

         </arguments>

        .

        .

      </block>

In Block - Grid.php

    namespace NamespaceModuleBlockAdminhtmlTest;



    use MagentoBackendBlockWidgetGrid as WidgetGrid;



     class Grid extends WidgetGrid

        {

          public function _construct()

           {

            parent::_construct(); 

            if ($this->hasData('default_filter')) {

            // print_r($this->getData('default_filter'));die;

            $this->setDefaultFilter($this->getData('default_filter'));

           }

        }

      }

I have followed this link to create admin grid in magento 2

http://www.mage-world.com/blog/grid-and-form-in-magento-2-admin-panel-part-1.html

If you define grid collection thought layout than you can use updater to add default filter.

<argument name="dataSource" xsi:type="object">

    TutorialSimpleNewsModelResourceNewsCollection

    <updater>TutorialSimpleNewsModelResourceNewsCollectionUpdater</updater>

</argument>

and

<?php

namespace TutorialSimpleNewsModelResourceNewsCollection;



class CollectionUpdater implements MagentoFrameworkViewLayoutArgumentUpdaterInterface

{



    /**

     * Update grid collection according to chosen order

     *

     * @param TutorialSimpleNewsModelResourceNewsCollection $argument

     * @return TutorialSimpleNewsModelResourceNewsCollection

     */

    public function update($argument)

    {

        $argument->addFieldToFilter('you_field', 'value');



        return $argument;

    }

}

or Extend Grid block

class Grid extends MagentoBackendBlockWidgetGrid

{

    protected function _prepareCollection()

    {

        if ($this->getCollection()) {

            foreach ($this->getDefaultFilter() as $field => $value) {

                $this->getCollection()->addFieldToFilter($field, $value);

            }

        }

        return parent::_prepareCollection();

    }   

}

you need to add this inside the arguments tag:

<argument name="default_filter" xsi:type="array">

    <item name="field_name_here" xsi:type="string">value here</item>

</argument>

if your arguments are contained in this block

<block class="MagentoBackendBlockWidgetGrid" name="some.name.here" as="grid">

you need to create your own class that extends MagentoBackendBlockWidgetGrid like this:

<?php 

namespace NamespaceModuleBlockAdminhtmlWhatever;



class Grid extends MagentoBackendBlockWidgetGrid

{

    public function _construct()

    {

        parent::_construct(); 

        if ($this->hasData('default_filter')) {

            $this->setDefaultFilter($this->getData('default_filter'));

        }

    }

}

and modify the block tag above to

 <block class="NamespaceModuleBlockAdminhtmlWhateverGrid" name="some.name.here" as="grid">

if you already use a custom grid and not the default MagentoBackendBlockWidgetGrid you don't need to create the class.

You just need to copy the _construct method from above in your class.

here is the reference on devdocs:

http://devdocs.magento.com/guides/v2.0/ui-components/ui-secondary-filter.html

If You need more info on that - you can create a pull request or an issue via docs page - just click "Edit this page on GitHub" link. Docs are constantly updated and improved.

After trying many codes which doesn't work, finally find a way doesn't need coding - make use of saving custom views function which could save filter and column settings.

Specific steps

After setting filter and column settings, click on the Default View button with the eye icon, then click Save View As… to enter a name for your view. Then you could click the custom view whenever you want to get the grid just the way you like it, and you can save custom views as many as you like.

You can also go back and use the edit icon to rename it or delete it later on, or to return to the default view.

I think this is a very good function in Magento 2 :)
