Datagrid editing

[Stewart]

Sorry for the cross post. Not sure which forum covers
these issues:

I'm hoping someone can help me figure out what I'm missing
in my code.
I am trying to configure a Datagrid for editing. So far
everything works well in terms of displaying, switching
modes, etc. What is not working is my Update code. I get
the error: There is no row at position 0.

Here is a the snippet that is not working:

Private Sub dgPhase_UpdateCommand(ByVal source As
Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs )
Handles dgPhase.UpdateCommand
'Update each of the columns in the dataset row
Dim PhaseRow As DataRow = DsPhase1.Phase
(e.Item.DataSetIndex)
Dim i As Integer, iMax As Integer =
DsPhase1.Phase.Columns.Count
For i = 1 To iMax
'Update Phase dataset columns with edits from
datagrid (dgPhase)
If e.Item.Cells(i).Controls.Count > 0 Then
'Cast control to textbox
Dim txtEdit As TextBox = CType(e.Item.Cells
(i).Controls(0), TextBox)
Dim sColumnName As String =
DsPhase1.Phase.Columns(i - 1).Caption
PhaseRow(sColumnName) = txtEdit.Text
End If
Next

If Me.DsPhase1.HasChanges() Then
'Update the database
Me.SqlDataAdapter2.Update(Me.DsPhase1.Phase)
End If

dgPhase.EditItemIndex = -1
SqlDataAdapter2.Fill(DsPhase1)
dgPhase.DataBind()
End Sub
