button help

Question

Hi there,

I have a windows form application ... i have bunch of checkboxes on it and when i click on a button it checks those checkboxes...

i wanna add this one thing...i want the checkboxes to get unchecked when i click on the button again..

how do i do that.. and may be when i check it the
first time it checks the checkboxes and make the button pop out and when i check on it again it unchecks the checkboxes and button then appreas to be normal

also, would it be possible for me to create a switch custom control that will behave as a button

i mean when i click one side of the switch it check the checkboxes and when i click the other it unchecks them

Please get back to me with whatever you can offer

Thanks alot
