specify a datakeyfield in your datalist like

<asp:datalist datakeyfield="productid" ...

then in your itemcommand

intProductID = DataList.DataKeys(e.Item.ItemIndex)
 
hey
ur solution will work only if my datalist postback in every selection
and this is not what happen here
i have a datalist multiple checkbox
i want to get the id of the item that have a checked checkbox
my datalist wil postback only when the user click the button and the itemindex will be -1
hope u have another solution for me
 
Something like this..

Code: 
Private Sub Button1_Click(s as object, e as event args) handles Button1.Click
   Dim item As DataGridItem
   Dim mycheckbox as checkbox
   Dim intID As Integer
   For each item in Datagrid1.Items
      mycheckbox = item.findcontrol("CheckBox1")
      intID = DataGrid1.Datakeys(item.itemindex)
      If mycheckbox.checked then
         ..your code
      end if
   Next
End Sub
