if I were you I would use below algorithm

Code:

private void delete_Click(object sender, System.EventArgs e)
{
   foreach(DataListItem anItem in DataList1.Items)
   {
   if (((CheckBox)anItem.FindControl("CheckBox")).Checked)
     {
  //1-I delete from datasource through an deletecommand(like "DELETE yourtable WHERE [email protected]",you should use parameters here)  the row which it's number is according to anItem.ItemIndex
     }
   }
//2-I retrieve new datasource and bind my datalist
}

HTH.
