how do i insert value to CKEditor Asp.net

Hi i having a querystring where i get an id.
Then I select the ID from my db and are ready to use the value, but hov do I insert the value into CKEditor !?

Have used google for 2 days now, and i cant find any usefull solution, and the installe guide is not showing an usefull solution.

And then its now true, there is solutions but its when i write a new text, here i want to get an old text from my db to my ckeditor so I can edit it and then save it again in my db.

Code_behind

Protected Sub Page_Load(sender As Object, e As EventArgs)
        If Request.QueryString("editid") Is Nothing Then
        Else
            Dim textid = Request.QueryString("editid")
            Dim strSQL As String = ""

            strSQL = "" & _
            "SELECT * " & _
            "FROM shop_histo " & _
            "WHERE (shophis_id = '" & textid & "');"

            Using connection As OleDbConnection = New OleDbConnection(ConfigurationManager.ConnectionStrings("ConnStr").ConnectionString)
                Using command As OleDbCommand = New OleDbCommand(strSQL, connection)
                    Try
                        command.Connection.Open()
                        Using reader As OleDbDataReader = command.ExecuteReader(CommandBehavior.CloseConnection)
                            If reader.HasRows Then
                                Dim text_title = reader("shophis_title")
                                Dim text_note = reader("shophis_text")
                            End If
                            reader.Close()
                        End Using
                    Catch exc As Exception

                    Finally
                        command.Connection.Close()
                    End Try
                End Using
            End Using
        End If
    End Sub
