Setting a Toggle button value dynamically

SilkTest Workbench 16.5

I am a newbie on this tool.  Am developing a .net script to read data from excel file and populate the relevant fields.
Can a toggle-button (with states On and Off) be set dynamically i.e. if 'On' is passed in, the button is set to 'On'.

While doing the initial recording using the <TAB> key,  code generated uses DomLink. 

While using the mouse, the code generated is .DomElement(On).DomClick(MouseButton.Left, New Point(16, 5))

Can someone point to an example where  the value of such a field is populated. 

All help appreciated.
