public class Form2 : Form {
private Object _DataSource;
public Object DataSource {...}
}

public class Form1 : Form {
public void HandleShowForm2Click(Object sender, EventArgs e) {
Form2 form = new Form2();
if (form.ShowDialog() == DialogResult.Cancel) {
return;
}

Object yourResult = form.DataSource;

}
}

The form may be closed (i.e. not visible), but the object still remains
in memory. Just create some public properties on Form2 with your return
information and you can access them in the calling form:

Form2 form = new Form2();
if (form.ShowDialog() == DialogResult.OK)
{
if (form.ReturnData = "itworks")
...
}
