common delete scenario for datalist is as follows..

VB

Sub Delete_Command(ByVal sender As Object, _
                       ByVal e As DataListCommandEventArgs)
        '---retrieves the key for the row that you want to delete---
        Response.Write(DataList1.DataKeys(e.Item.ItemIndex))
        '---codes to delete row here----
         End Sub
