I'm pretty sure the problem is that you forgot to call the DataBind() method, try this:

    protected void companyForm_ItemCommand(object sender, FormViewCommandEventArgs e) 
    {
         if (e.CommandName == "Cancel")
         { 
             companyForm.ChangeMode(FormViewMode.ReadOnly);
             companyForm.DataSource= <THE SOURCE> ;
             companyForm.DataBind();
         }
    }
