I have an application where the Datasource of a ListBox is a datatable or a dataview.

Sometimes when the list box is displayed it shows the 5 items correctly, at other time it shows System.Data.DataRowView as the text for each item. How can I ensure that it always shows teh text correctly?

Sub PopulateGlobeList(ByRef r_lst As ListBox)

            Dim oKey(0) As System.Data.DataColumn
            Dim tblGlobe As DataTable

            r_lst.BeginUpdate()

                '  Creat and populate data table
                  .......

                ' Set key and sort info
                oKey(0) = tblGlobe.Columns("GlobeID")
                tblGlobe.PrimaryKey = oKey
                tblGlobe.DefaultView.Sort = "GlobeText"

                ' ---- and bind to the the list box
                r_lst.DataSource = tblGlobe.DefaultView
                r_lst.ValueMember = "GlobeID"
                r_lst.DisplayMember = "GlobeText"

            r_lst.EndUpdate()

End Sub

the only time i have that problem occur is if i have not yet set the displaymember property or if i have set it incorrectly
it might pay to spend some time testing to see what is different when the list displays correctly and incorrectly

p.s im pretty sure you dont need to include the DefaultView part of your datasource you should find that the data will display as sorted without it
