I want to load my grid class within constructor method of other block.I try this peace of code but don't succeed.

`class Mymodule_Block_Adminhtml_Sales_Order_View_Tabs  extends 
    Mage_Adminhtml_Block_Sales_Order_Abstract
        implements Mage_Adminhtml_Block_Widget_Tab_Interface
    {

        protected $_chat = null;

        protected function _construct()
        {
            parent::_construct();
               $class = Mage::getConfig()->getBlockClassName('mymodule/adminhtml_mymodule_edit_tab_tickethistory');   
                $block = new $class;
               $block-> _prepareCollection();

        }
    } .

You can load a block like this:

Mage::app()->getLayout()->createBlock('identifier/here');

in your case:

Mage::app()->getLayout()->createBlock('mymodule/adminhtml_mymodule_edit_tab_tickethistory');

but what you are trying to do won't work because _prepareCollection() is a protected method. You can only call it inside the class methods or it's descendants.
I think it's better to explain the problem you have, not the problems you have while implementing the solution. Maybe someone has a better idea on how to do it.
