Hello everyone,

I am dynamically filling a TextBox's AutoCompleteSource from an Oracle Database.

I want to use a Button click event to initiate action.

I can't seem to get a new list each time the button is clicked.

Here is the code snippet:

        Dim List1 As New List(Of String)
        Dim strSQL As String = "SELECT DISTINCT Value1 from Table1 ORDER BY Value1"
        Try
            Using cnn As New OracleConnection("USER ID=User1;DATA SOURCE=Data1;PASSWORD=PASS1;PERSIST SECURITY INFO=true;")
                Using cmd As New OracleCommand(strSQL, cnn)
                    cnn.Open()
                    Using dr As OracleDataReader = cmd.ExecuteReader
                        While dr.Read()
                            List1.Add(dr("Value1").ToString())
                        End While
                    End Using

                    cnn.Close()
                End Using
            End Using
        Catch ex As Exception

        End Try
        Dim Array1() As String = List1.ToArray
        TextBox1.AutoCompleteMode = AutoCompleteMode.Suggest
        TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
        TextBox1.AutoCompleteCustomSource.AddRange(Array1)

Thanks everyone!
