search a record

[grey15]

hi...i have an application which stores records in a text file. the application loads the records in array of objects when the page is loaded. then, we can add, search, delete the records in array and save the array back to the file. code for inserting new record and then saving it works fine. am havin problem wid searching. search is based on ID.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Dim d As New Developer
            Dim reader As System.IO.StreamReader
            Dim strInput As String
            If File.Exists(Request.MapPath("developer.txt")) Then
                reader = System.IO.File.OpenText(MapPath("developer.txt"))

                While reader.Peek <> -1
                    strInput = reader.ReadLine()
                    Dim splitout As String()
                    splitout = Split(strInput, " ")

                    d.DeveloperID = splitout(0)
                    d.Name = splitout(1)
                    d.Salary = splitout(2)
                    DeveloperBook.Add(d)
                End While
                Session("Developer") = DeveloperBook
            Else
                MsgBox("File not found")
            End If
        End If
    End Sub

Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click
        Dim d As New Developer
        Dim DeveloperBook As ArrayList = getSession()
        Dim i As Integer
        For i = 0 To DeveloperBook.Count - 1
            If CType(DeveloperBook(i), Developer).DeveloperID = txtID.Text Then
                txtName.Text = CType(DeveloperBook(i), Developer).Name
                txtSalary.Text = CType(DeveloperBook(i), Developer).Salary
                Exit For
            End If
        Next
        Session("Developer") = DeveloperBook

    End Sub

 Private Function getSession() As ArrayList
        Return CType(Session("Developer"), ArrayList)
    End Function

What is the problem? Do you get an error message? Are you clearing your sessions?
