>First, decide where you'll store this information and how. You can use a table, XML file, INI file, etc.

A form.
Drop a optiongroup on a form set the value to 2 from Data tab of form designer.
Now run the form, the Init value of optiongroup is 2. Where is this value saved in the form? In runtime the value is change to 1 now store the value 1 to the place where value 2 was saved.
But I don't know where is was save :(
