'align' => 'center',
'width' => '150px',
'renderer' => 'giftcard/adminhtml_giftcard_idrenderer',
'index' => 'giftcard_id',
));
any one can help me how to fix it
Advance Thanks
probably the renderer class
not found.
try with
'renderer' => 'troy_giftcard/adminhtml_giftcard_idrenderer',
It's due to Magento generates exception for renderer class as Invalid block for it.
Ex : 'renderer' => 'Custom_Sales_Block_Adminhtml_Report_Sales_Grid_Column_Renderer_Status'
Mean above class is not valid block due to some path mismatch or layout not found issue.
