Updating a datagrid

[Rocketdawg]

Never mind

Changed the load event to

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        
        objCartDT = Session("Cart")
        If objCartDT Is Nothing Then
            lblNoItems.Text = "There are no items in your cart."
        Else
            lblTotal.Text = "Total: $" & GetItemTotal()
        End If
 
        If Not IsPostBack Then
            ' need to load this data only once
            BindGrid()
        End If
 
    End Sub
 
    Sub BindGrid()
        dgCart.DataSource = objCartDT
        dgCart.DataBind()
    End Sub

And it works fine now.
