ASP.Net - ListView - Hiding a Column

Occasionally, I’ll have a column on the listview that I want hidden.

Here is an example where I am hiding a column if the mode attribute of a viewstate is ‘unpaid’.

2 events are involved:

• PreRender - to hide columns in the header
• Item Databound - to hide columns from rows being displayed.

    Protected Sub lv_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles lv.PreRender

        '
        ' do not show the payment date if the mode is 'UnPaid' 
        ' since they are blank anyway
        '

        Select Case ViewState("Mode").ToString.ToLower
            Case "unpaid"
                Dim PaymentDateSortButton As LinkButton _
                    = CType(lv.FindControl("Payment_DT"), LinkButton)
                PaymentDateSortButton.visible = False
                Dim TextBox_PaymentDT As TextBox _
                    = CType(lv.FindControl("TextBox_PaymentDT"), TextBox)
                TextBox_PaymentDT.Visible = False
        End Select
    End Sub

Protected Sub lv_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) Handles lv.ItemDataBound
        If e.Item.ItemType = ListViewItemType.DataItem Then
            Dim lvdi As ListViewDataItem = e.Item
            Select Case ViewState("Mode").ToString.ToLower
                Case "unpaid"
                    Dim Label_PaymentDT As Label _
                        = CType(e.Item.FindControl("Label_PaymentDT"), Label)
                    Label_PaymentDT.visible = False
            End Select
        End If
    End Sub
