    Urgent.. prob w/ Datagrid edit button

    I had a successfully deployed datagrid reading an XML file and
    showing the data:

    Private Function MakeDataView() as DataView
    Dim myDataSet As New DataSet()
    myDataSet.ReadX ml(Server.MapPa th("TimberSales .xml"))
    Dim view As DataView = New DataView(myData Set.Tables(0))
    view.AllowDelet e = False
    view.AllowEdit = True
    view.AllowNew = False
    view.Sort = "Year ASC"
    Return view
    End Function


    Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    Dim view as DataView = MakeDataView()
    dgTimber.DataSo urce = view
    dgTimber.AllowS orting = True
    dgTimber.DataBi nd()
    End Sub
    _______________ _______________ _______________ _______________ __________


    I wanted to add an "Edit" button as desribed at:

    Private Sub dgTimber_EditCo mmand(ByVal source As Object, _

    Handles dgTimber.EditCo mmand
    dgTimber.EditIt emIndex = e.Item.ItemInde x
    dgTimber.DataBi nd()
    End Sub


    Dim newData As String
    Dim aTextBox As TextBox
    aTextBox = CType(e.Item.Ce lls(1).Controls (0), TextBox)
    **** says "aTextBox" is not declared, (?)
    newData =
    aTextBox.Text **** says
    "newData" is not declared, (?)


    Private Sub dgTimber_Update Command(ByVal source As Object, _
    ByVal e As System.Web.UI.W ebControls.Data GridCommandEven tArgs) _
    Handles dgTimber.Update Command
    Dim quantityCell As TableCell = e.Item.Cells(6)
    Dim quantityBox As TextBox = _
    CType(quantityC ell.Controls(0) , TextBox)
    Dim quantity As Integer =
    System.Int32.Pa rse(quantityBox .Text)
    dgTimber.EditIt emIndex = -1
    dgTimber.DataBi nd()
    End Sub


    When I hit the Edit Button I get this:


    Invalid postback or callback argument. Event validation is
    enabled
    using <pages enableEventVali dation="true"/>
    in configuration or <%@ Page EnableEventVali dation="true" %in a
    page. For security purposes, this feature ....etc.


    Does anything obvious stabd out as the potential probelm? Thank You!

          Re: Urgent.. prob w/ Datagrid edit button

          Thanks... that worked... now I need to write an event handler for the
          buttons:

          My code within the datagrid describes the buttons:

          <asp:EditComman dColumn ButtonType="Pus hButton"
          CancelText="Can cel"
          EditText="Edit" UpdateText="Upd ate"
          CausesValidatio n="false"></asp:EditCommand Column>

          I'm having difficulty following the tutorial's association with this
          dg's button and this code:

          Private Sub dgTimber_EditCo mmand(ByVal source As Object, _
          ByVal e As System.Web.UI.W ebControls.Data GridCommandEven tArgs) _
          Handles dgTimber.EditCo mmand
          dgTimber.EditIt emIndex = e.Item.ItemInde x
          dgTimber.DataBi nd()
          End Sub

          Private Sub dgTimber_Update Command(ByVal source As Object, _
          ByVal e As System.Web.UI.W ebControls.Data GridCommandEven tArgs) _
          Handles dgTimber.Update Command
          Dim quantityCell As TableCell = e.Item.Cells(6)
          Dim quantityBox As TextBox = _
          CType(quantityC ell.Controls(0) , TextBox)
          Dim quantity As Integer =
          System.Int32.Pa rse(quantityBox .Text)
          dgTimber.EditIt emIndex = -1
          dgTimber.DataBi nd()
          End Sub

          Basically what I want is when I hit the edit button a textbox
          displays below the datagrid and the users can type in the new info and
          the button will change to Update upon which pressing that will write
          the constents of the textbox to the database (and a postback refresh
          will show the updated info).
