Changing default product view per page in backend

Question

By default, in catalog - > manage product, magento shows 20 products, is it possibile to set the default number to, 50, 100 or 200 ?

Answer 1

Go to your /app/code/core/Mage/Adminhtml/Block/Catalog/Product/Grid.php

Search the file for a line of code that reads:

parent::__construct();

Once you find it, paste the below code on the line beneath it:

$this->setDefaultLimit(100);

PS : Do not edit the core files, you should overwrite it

Answer 2

try to Edit the grid.phtml file located:

.../app/design/adminhtml/default/default/template/widget/grid.phtml

At line 81-87:

<select name="<?php echo $this->getVarNameLimit() ?>” onchange="<?php echo $this->getId() ?>JsObject.loadByElement(this)"> 
  <option value="20"<?php if($this->getCollection()->getPageSize()==20): ?> selected="selected"<?php endif; ?>>20</option> 
  <option value="30"<?php if($this->getCollection()->getPageSize()==30): ?> selected="selected"<?php endif; ?>>30</option> 
  <option value="50"<?php if($this->getCollection()->getPageSize()==50): ?> selected="selected"<?php endif; ?>>50</option> 
  <option value="100"<?php if($this->getCollection()->getPageSize()==100): ?> selected="selected"<?php endif; ?>>100</option> 
  <option value="200"<?php if($this->getCollection()->getPageSize()==200): ?> selected="selected"<?php endif; ?>>200</option> 
</select>

Changing the above to the below for example:

<select name="<?php echo $this->getVarNameLimit() ?>” onchange="<?php echo $this->getId() ?>JsObject.loadByElement(this)"> 
  <option value="200"<?php if($this->getCollection()->getPageSize()==200): ?> selected="selected"<?php endif; ?>>200</option> 
  <option value="300"<?php if($this->getCollection()->getPageSize()==300): ?> selected="selected"<?php endif; ?>>300</option> 
  <option value="500"<?php if($this->getCollection()->getPageSize()==500): ?> selected="selected"<?php endif; ?>>500</option> 
  <option value="1000"<?php if($this->getCollection()->getPageSize()==1000): ?> selected="selected"<?php endif; ?>>1000</option> 
  <option value="2000"<?php if($this->getCollection()->getPageSize()==2000): ?> selected="selected"<?php endif; ?>>2000</option> 
</select>

Hope this helps. Thanks
