Hi all, when I try to update a row value in MMGridView, there is an error saying tat
"Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index". The following is my code in RowUpdating event, any advice would be appreciated, thanks.

    Protected Sub loGridView_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles loGridView.RowUpdating
        ' Get the item to be updated
        Me.loGridView.EditIndex = e.RowIndex
        ' Retrieve the previous Order Detail DataSet
        Dim dsClmDetail As DataSet = CType(Session("dsClmDetail"), DataSet)
        ' Save the DataSet (the GridView automatically binds back)
        Me.Save(Me.oBxclaimd, dsClmDetail)
        ' Reset the edited item and rebind the GridView
        Me.loGridView.EditIndex = -1
        Me.BindControl(Me.loGridView)
    End Sub
