Hi,

Try this if could help...

 //instantiate new ArrayList to hold our checked items
 ArrayList checkedItems = new ArrayList();
 CheckBox chk;
 string chkBoxIndex = string.Empty;
 //loop through each row in the GridView
 foreach (GridViewRow row in GridContacts.Rows)
 {
    //get the index of the current CheckBox
    chkBoxIndex = (string)GridContacts.DataKeys[row.RowIndex].Value.ToString();
    chk = (CheckBox)row.FindControl("CheckBox1");
    if (!(Session["CheckedItems"] == null))
    {
      checkedItems = (ArrayList)Session["CheckedItems"];
    }
    if (chk.Checked)
    {
      if (!(checkedItems.Contains(chkBoxIndex)))
      {
         //add to the list
         checkedItems.Add(chkBoxIndex);
      }
      else
      {
         //remove from list since it's unchecked
         checkedItems.Remove(chkBoxIndex);
      }
    }
}
if (checkedItems.Count > 0)
{
   for (int i = 0; i < checkedItems.Count; i++)
   {
       // Your code to delete the items in you database here...
       //...
   }
}
