Why not just configure a loadMask right in the grid's constructor instead? ('loadMask' config option).

tht can be done , but i want to do this way..why it is not working but..?
take care

I would be curious to know why you want to to it this way, since if you configure it in the constructor the hide/show events will be managed for you automatically...
But I am betting the error is because you are trying to create the loadMask before the grid has been rendered, which will not work.
