I would like to check all of the checkbox made by Ext.grid.CheckColumn in a gridpanel, may I know if there is any easy way to do this? I have try to add class to the checkbox(Ext.grid.CheckColumn) but it seem not work.
Thanks very much!

If you're rendering a store field as a checbox column, you have to set that field to true for all the records in the store.
store.each(function(rec){ rec.set('field', true) })
Never try to change a grid cell's value directly, always change it via the store's corresponding record.
Update: if you have many records, use something like this:
store.suspendEvents(); // avoid view update after each row
store.each(function(rec){ rec.set('field', true) })
store.resumeEvents();
grid.getView().refresh();
