Hi Jamal: Tried the below with the same results.Note that the e-mailer is making things wrap in the wrong places, everything is ok in that respect.
Mabey I can't iterate the ListBox using the ListBox controls at all after binding it to something?
I wonder if only the nav for the DataTable or DataView is what works.for bound controls.
Here is the latest code: Public Class frmStocksReport dim Dt As StockFDataSet.StocksDataTablePrivate Sub lbStocksReportNdx_SelectedIndexChanged( ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles lbStocksReportNdx.SelectedIndexChanged MessageBox.Show( "Index is " & lbStocksReportNdx.SelectedIndex.ToString()) Note: The above still returns 0 for all ListBox entries MessageBox.Show( _ DirectCast( _ lbStocksReportNdx.SelectedItem, DataRowView)("Ticker").ToString()) The Above still returns the ticker for the first entry in the ListBox.By the way, I just dropped the ListBox on the form in the VS IDE and the events seem to be there as I am using them.
End SubPrivate Sub frmStocksReport_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dt = New StockFDataSet.StocksDataTable() Dim StocksAdapter As New StockFDataSetTableAdapters.StocksTableAdapter() Dt = StocksAdapter.GetAllRows() lbStocksReportNdx.DisplayMember = "Name" lbStocksReportNdx.ValueMember = "Ticker" lbStocksReportNdx.DataSource = Dt End Sub End Class----- Original Message ----- From: "Jamal Mazrui" <empower@xxxxxxxxx>

Data binding should be able to do what you want. In examining the code, it appears that a right parenthesis should be moved after ToString() rather than before it. Also, should it read SelectedIndex.ToString() rather than SelectedItem.ToString()? When declaring the ListBox, did you use the WithEvents keyword?

This works fine. I can arrow up and down and the entries are correct.I can not read the entries in the ListBox into a TextBox.Even though I arrow up and down the list and the IndexChanged event fires the TextBox always shows the first entry in the list.Public Class frmStocksReport dim Dt As StockFDataSet.StocksDataTablePrivate Sub lbStocksReportNdx_SelectedIndexChanged( ByVal sender As System.Object, ByVal e As System.EventArgs) _Handles lbStocksReportNdx.SelectedIndexChanged MessageBox.Show( "item is " & lbStocksReportNdx.SelectedItem).ToString() Note: the above always shows the index as 0.' tbDescription.Text = _ MessageBox.Show( _ DirectCast( _ lbStocksReportNdx.SelectedItem, DataRowView)("Ticker").ToString()) Note: The above always shows the first item's Ticker Symbol. End SubDo I somehow need to synch the underlying DataView or DataTable to the ListBox Selected Item somehow?Should I scrap the whole DataBinding senario? Any Ideas? Rick Farmington Mich.
