modtage _click event / commandname. (simpelt)

Hej,

Jeg er ret ny i .net. Det jeg gerne vil lave er at slette en post (+ meget andet) ved at sende en _click event fra min Column med commandname Delete. Hvordan modtager jeg variablen ? (har makeret det i koden, hvis det er en hjælp. (alt ligger i samme aspx fil)







Sub Delete_Click(sender As Object, e As EventArgs)
        Dim strConnect As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source="& Server.MapPath("../db/db.mdb") &";"
        Dim objConn As New OleDbConnection(strConnect)
        Dim objCmd As New OleDbCommand()
       
        With objCmd
            dim folder as integer
            'folder = <--- hvordan requestes commandname ???
            .Connection = objConn
            .CommandText = "DELETE FROM tblDirectory WHERE id = = '" + folder + "'"   
        End With
       
        Try
            objConn.Open()
            objCmd.ExecuteNonQuery()
        Finally
            objConn.Close()
        End Try
   
    End Sub
