I'm kind of confused. Have you made one form and are calling it twice and want to show different data in each call.

Code
{
Form1 frm = new Form1();

frm.ChangeDataSource(firstDataSource);
frm.Show(); // show first set of data
frm.ChangeDataSource(newDataSource); // change the data source
frm.Show(); // show second set of data
}

Or have you made two forms, which you call once each and you want to show different data in different forms.

Code
{
Form1 frm1 = new Form1();
Form2 frm2 = new Form2();

frm1.Show(); // show first set of data
frm2.Show(); // show second set of data
}

1) create a list
2) connect to what ever datasource you need and populate your list in 1
3) repeat step 2 for all datasources
4) data bind your combo box to the list in 1

A generic list of the type of object you want to bind to. For example in the simplest case it might be list<string>

You don't mean 'the same control'. You mean 'two instances of the same control class'.

If it inherits from ComboBox (or it contains a ComboBox which you can access via a property), you can use normal data binding: set the DataSource of the ComboBox to a list* of the appropriate type, a different list for each form. You can do the binding in the form's constructor (after the call to InitialiseComponent where the combos are set up, if you used the designer).

(*: or data table or database binding adapter or etc)

You need to show at least the skeleton of the user control you're trying to do this with first.
