You can pass the custID as int to the deletecustomer function and delete the record having custID.
After the function call, you can reload/refresh the listview, in the button1_click().

C#

public void Deletecustomer(int CustID)
    {

        CustomerDataContext db = new CustomerDataContext();
        Table<customerdetails> tblCustomerDetails = db.Gettable<customerdetails>();
        CustomerDetails selectedCustomer = (CustomerDetails)tblCustomerDetails.Select(c=>c.custID == CustID);
        db.tblCustomerDetails.DeleteOnSubmit(selectedCustomer);
        db.SubmitChanges();
    }

Does this help you?

Regards
Swami

Rewite Button1_Click following way....

C#

protected void Button1_Click(object sender, EventArgs e)
   {
       CustomerDataContext db = new CustomerDataContext();
       
       foreach (ListViewItem itemRow in lvCustomer.Items )
       {

           Label  CustID = ((Label)itemRow.FindControl("Cust_IDLabel"));
           int a = int.Parse (CustID.Text);
	   db.tblCustomerDetails1s.DeleteAllOnSubmit(db.tblCustomerDetails1s.Where(c => c.CustID == a));

        }
	db.SubmitChanges();

   }
