c# - How do I show a form only when data is loaded? -

i need on thing can't resolve.

i've windows form datagridview populated large amount of data. data stored in sql server database , retrieved simple piece of ado.net code.

i'm using backgroundworker class perform kind of operation form still freezes 1-2 second.

is there way delay showing of form? show form when data in loaded? i've tried make not visible or use hide() , show() method still not have results.

remove initializecomponent(); constructor of form , call method when data has loaded
