Changing checkbox appearance to button

I am using a checkbox as a toggle switch (ON-OFF Button) by changing its appearance to Button using checkbox.appearance() property. When i run the vb.net application, the checkbox turns into a button only after the first click. Is it possible to change the appearance of the checkbox to button as default? I also want the button to Popup when the user clicks "ON". I have tried changing the appearance using "Flat Style" property, but it doesn't work.
