I created my own collection with custom data. This is part from my grid class:

 my grid class extends Mage_Adminhtml_Block_Widget_Grid
 ...
 $this->setCollection($collection);
 array_walk($data['data'], function($order) use (&$collection) 
 $collection->addItem(new Varien_Object([
 'store_id' => $order['store_reference'],
 'shipping_date' => $order['shipping_date'],
 'order_reference' => $order['order_reference'],
 'customer_reference' => $order['customer_reference'],
 'updated_at' => $order['updated_at'],
 'shipping_fullname' => "$order['shipping_firstname'] $order['shipping_middlename'] $order['shipping_lastname']",
 ]));
 );
 $collection->setCurPage($page);
 $collection->setLastPageNumber($lastPage);
 $collection->setSize($lastPage * $limit);

 $this->setCollection($collection);
 return $this;

where $collection is an instance of class which extends Varien_Data_Collection. The content of that class is:

 protected $hardSetSize = 1;
 protected $setLastPageNumber = 1;
 /**
 * @param int $size
 */
 public function setSize(int $size)
 
 $this->hardSetSize = $size;
 
 /**
 * Retrieve collection all items count
 *
 * @return int
 */
 public function getSize()
 
 return $this->hardSetSize;
 

 public function setLastPageNumber(int $lastPage)
 
 $this->setLastPageNumber = $lastPage;
 

 public function getLastPageNumber()
 
 return $this->setLastPageNumber;
 

My grid is displayed, I got my custom data. But there is filtering problem.
I created my column like:

 $this->addColumn('store_id', [
 'header' => Mage::helper('ffm_fulfillment')->__('Store'),
 'align' => 'left',
 'index' => 'store_id',
 'renderer' => 'Mynamespace_Mymodule_Block_Adminhtml_Test_Grid_Renderer_Store',
 'filter_condition_callback' => [$this, '_storeFilter'],
 ]);

I got the render data, which are store ids from 1-20. I want to filter them. I created my _storeFilter function. What should I do next ? I put a message and the exit() in my function and on filtering I do not get my message.

protected function _storeFilter($collection, $column)

 $value = $column->getFilter()->getValue();
 echo 'Test'; exit();

I have checked your mentioned code and found you have wrong defined 'filter_condition_callback' => [$this, '_storeFilter'],

From
'filter_condition_callback' => [$this, '_storeFilter'],
To
'filter_condition_callback' => array($this, '_storeFilter'),
