    Finding BindingSource.Position from Listbox Selection

    Hi,
    I'm have a form with a listbox and a few textboxes on it. Based on
    the user's selection in the listbox, I want the bindingsource to
    update the textboxes with the corresponding values. I have similar
    code built for a combobox that works just fine, but when applying it
    to a listbox bound to a dataview, I can't figure out how to return the
    correct bindingsource index. No matter what item I select, my index
    returns 0.

    Private Sub lbUOM_SelectedI ndexChanged(ByV al sender As Object, ByVal e
    As System.EventArg s) Handles lbUOM.SelectedI ndexChanged

    cn.Open()

    Dim drv As DataRowView = CType(lbUOM.Sel ectedItem,
    DataRowView)
    tb.Text = drv.Item("USUOM ").ToString

    Dim index As Integer = bsUOM.Find("USU OM", tb.Text)
    If index <-1 Then 'it was found; move to that
    position
    bsUOM.Position = index
    End If

    cn.Close()
    End If
    End Sub

    Can anybody see why this doesn't work? Is there a better way to
    navigate the bindingsource based on a listbox selection? I don't see
    this issue posted anywhere in this board.

    Thanks,
    Randy

                  solution?

                  Hi Randy,

                  Did you find a solution to this? I have a combo box bound to a Access db Table - column 1. When the combo item is selected I want the same records column 2 entry to display in a text box. I'm struggling to get a decipherable explanation on how to use BindingSource for .net 2005.

                  Any help would be gratfully received.

                  Thanks,
                  Nick

                      Nick,

                      That goes automaticly as you databind the textbox to a table, and you do the
                      same for the combobox using the datasource, then the currencymanager will
                      set the current table-item in the textbox.

                      You even need a New DataView for not doing that.

                      I would use this newsgroup for information instead of the by you quoted one.
                      This is common stuff here.
