Bulk edit/update in admin grid pannel

Question

I have created my own grid in magento admin with custom table. Now I would like to edit/update rows from grid panel. So that I can perform bulk edit/update. No need to open each item and edit/update.

I have seen few great extensions. For example this one.

I am sure I need to use some kind of Ajax to achieve this but not sure.

Can anyone guide me to right direction please.

Answer 2

for editing in grid column you need to add 'editable' =>true,

$this->addColumn(
'code', array(
'header' => Mage::helper('modulename')->__('Code'),
'align' => 'left',
'width' => '110px',
'index' => 'code',
'editable' =>true,

)
);
