  The ItemCreated event will be called whenever there is a new Item created. Here you just place this code:
  
  

  void Item_Created(Object Sender, DataGridItemEventArgs e)

  {

     if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

     {

         ImageButton _myButton = (ImageButton)e.Item.FindControl("btnDelete");

         _myButton.Attributes.Add("onclick", "return confirm('Are your sure ');");

     }

  }
  

  
  Then make sure you have set the ID attribute in you HTML:
  

  <asp:DataGrid id="MyDataGrid" AutoGenerateColumns="false" runat="server">

  <columns>

      <asp:TemplateColumn>

          <itemtemplate>

              <asp:ImageButton ID="btnDelete" ImageUrl="btnDelete.jpg" runat="server" />

            </itemtemplate>

          </asp:TemplateColumn>

          <asp:BoundColumn DataField="Name" HeaderText="Name" runat="server" />

          <asp:BoundColumn DataField="Phone" HeaderText="Phone Number" runat="server" />

          <asp:BoundColumn DataField="Address" HeaderText="Address" runat="server" />

          <asp:BoundColumn DataField="City" HeaderText="City" runat="server" />

      </columns>
  </asp:DataGrid>

  Why do you dislike it The ItemCreated is called whenever a Item (Line/Row) is rendered, you never know how many Item's a DataGrid will contain. That's why you write put it in the ItemCreated event.
  
  You say you are a newby, so don't screem that you dont like it.. first give it a try and when there are any problems or disadvantage please lett me know.
  
  I don't see why thit is a bad solution
  
  When you put it directly in you template, you can't add extra information. So in the ItemCreated event you can put:

  Control myControl = (Control)e.Item.FindControl("MyControlID");
  myControl.Attributes.Add("OnClick", return confirm('Are you sure you want to delete order# " + _order.Id + " ');");

  I dislike it...maybe because i'm newbie... i can't understand the item_created...

  i have it:

  private void DeleteCommand(object source,

  System.Web.UI.WebControls.DataGridCommandEventArgs e)

  {

  TableCell cell = e.Item.Cells[0];

  GestoreDB gestoreDB = new GestoreDB(DBConnection, DBTableName, Utente);

  gestoreDB.DeleteRow(Convert.ToInt32(cell.Text));

  BindData();

  }

  and in BLOCKED SCRIPT

  <script language="">

  function MsgOkCancel() {

  var fret;

  fret=confirm('are you sure');

  if (fret==true)

  {

  }

  }

  </script>

   

  <asp:TemplateColumn>< XML:NAMESPACE PREFIX = O />

          <itemtemplate>

              <asp:LinkButton onclick="msgokcancel" Commandname="delete" text="<img.../> runat="server" />

            </itemtemplate>

          </asp:TemplateColumn>

  In the ItemCreate event from the DataGrid put this:

  Control myControl = (Control)e.Item.FindControl("MyControlID");
  myControl.Attributes.Add("OnClick", return confirm('Are you sure ');");

  in this way (i refer your second message, not last) when i click yes, it executes the command in ItemCommand="xxx"
