Disabling the Cancel Button During an Installation

[C# Programming]

Hi,
I am making a setup file in Dot Net. I am opening one form during setup for doing some setup in between of installtion. I want to disable or hide the Cancel Button the installation form until and unless user does not saves the value on the other form. After he saves the values i want to enable the Cancel button.

Any reply will be appreciated.

Thanks
