Details view validation

Hi, I am looking to validate a detailsview as I select update.
I will be looking to check for null values, and checking some feild dependant on values on other field.
I have got my start off code attached but did not get far as it did not understand that I was trying to check if the field was blank and also id not recognize that I was trying to cancel the command if this was blank.

Any suggestions or examples you may have, would be most welcome.

Sub CustomerDetailView_ItemCommand(ByVal sender As Object, ByVal e As DetailsViewCommandEventArgs)
        Select Case e.CommandName
            Case "Cancel"
            Case "Update"
                If DetailsView1.DataItem("VCDescription") = "" Then
                    'cancel this command
                    DetailsView1.DataItem("VCDescription") = "dfgdsf"
                End If
            Case "Insert"
            Case Else
        End Select
    End Sub

Just wondering what is it that you want to Validate? The values in the textboxes right?
In that case you can use Validator controls in the markup itself.
For checking within the event, you can use individual events like:
ItemUpdating and there you do a e.Cancel=true to cancel the event if validation fails.

I'll be doing serveal check on the events.
the 2 bits in here I can't understand are
1) defining the content of the text field
If DetailsView1.DataItem("VCDescription") = "" Then
Does not work
2) Placing e.Cancel into the code above does not work as I get the responce
cancel is not a member of System.Web.UI.WebControls.DetailsViewCommandEventArgs
If I clear these two I should be able to push on.
Cheers
