Good Evening All,

I am writing a page that allows users to search a parts table, select quantities and a listbox is to be populated with gridview values. Here's a snippet of my aspx page:

<asp:ListBox runat="server" ID="lbItems" Width="155px">
<asp:ListItem></asp:ListItem>
<asp:ListItem></asp:ListItem>
<asp:ListItem></asp:ListItem>
<asp:ListItem></asp:ListItem>
<asp:ListItem></asp:ListItem>
</asp:ListBox>

Here's the relevant contents of codebehind:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    'Define DataTable Columns as incoming gridview fields
    Dim dtSelParts As DataTable = New DataTable
    Dim dr As DataRow = dtSelParts.NewRow()

    dtSelParts.Columns.Add("PartNumber")
    dtSelParts.Columns.Add("NSN")
    dtSelParts.Columns.Add("PartName")
    dtSelParts.Columns.Add("Qty")

    'Select those gridview rows that have txtQty <> 0
    For Each row As GridViewRow In MySearch.Rows
        Dim textboxText As String = _
        CType(row.FindControl("txtQty"), TextBox).Text
        If textboxText <> "0" Then
            'Create the row
            dr = dtSelParts.NewRow()
            'Fill the row with data
            dr("PartNumber") = MySearch.DataKeys(row.RowIndex)("PartNumber")
            dr("NSN") = MySearch.DataKeys(row.RowIndex)("NSN")
            dr("PartName") = MySearch.DataKeys(row.RowIndex)("PartName")
            'Add the row to the table
            dtSelParts.Rows.Add(dr)
        End If
    Next
    'Need to send items to Listbox control lbItems
    lbItems.DataSource = New DataView(dtSelParts)
    lbItems.DataValueField = "PartNumber"
    lbItems.DataValueField = "NSN"
    lbItems.DataValueField = "PartName"
    lbItems.DataBind()
End Sub

The page runs fine in that my search functiobnality is intact, and I can input quantity values into my gridview's textbox. When I click Add to Quote the Listbox receives focus, but no list items are visible. I've created several list items in the aspx page, however I don't know how to populate the contents of my datatable in the listbox. Can someone help a newbie with this, seemingly, easy issue?

Thanks, Sid
