Question

i have an input using the jquery autocomplete plugin. with this i want to return 5 results. I was making this happen by just entering 5 return results in the stored procedure that im using, but i want to remove duplicates, while still showing 5 results. im not sure the best way to go about doing this
here is my code behind for the callback page

Public Class SearchCallback
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Response.Clear()
    Dim searchText As String = Request("searchText")
    Dim searchField As String = Request("searchField")


    Dim dtCustomer As CustomerCollection = CustomerService.SearchRecords(searchText, searchField, "Contains", searchField, "Asc", CInt("1"), CInt("5"))
    Dim returnString As String
    If searchField = "Company" Then
        For Each drCustomer As Customer In dtCustomer
            If returnString = "" Then
                returnString = drCustomer.Company
            else
                returnString = returnString & "," & drCustomer.Company
            End If
        Next
        Response.Write(returnString)

i had a list of more searchfield options after that to give me the data i want. Im putting the needed info into a string so i can use it with my javascript code as follows.

$(document).ready(function () {
$(".searchTextBox").autocomplete({
    source: callback,
    autoFill: true
});
});

var callback = function (request, response) {
var searchText = request.term;
var searchField = $(".ddlist > option:selected").attr("value");
$.ajax({
    type: "GET",
    dataType: "text",
    url: "SearchCallback.aspx?searchText=" + searchText + "&searchField=" + searchField,
    success: function (data) {
        var splitData = data.split(",");
        response(splitData);
    }
});
}

everything works other then the duplication problem that im having.. please help!

its kinda messy but i got it working as i want with the following code

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Response.Clear()
    Dim searchText As String = Request("searchText")
    Dim searchField As String = Request("searchField")
    Dim lastValue As String
    Dim resultsCounter As Integer = 0

    Dim dtCustomer As CustomerCollection = CustomerService.SearchRecords(searchText, searchField, "Contains", searchField, "Asc", CInt("1"), CInt("100"))
    Dim returnString As String
    If searchField = "Company" Then
        resultsCounter = 0
        For Each drCustomer As Customer In dtCustomer
            If returnString = "" Then
                returnString = drCustomer.Company
                lastValue = drCustomer.Company
                resultsCounter += 1
            ElseIf resultsCounter < 6 Then
                If lastValue <> drCustomer.Company Then
                    returnString = returnString & "," & drCustomer.Company
                    lastValue = drCustomer.Company
                    resultsCounter += 1
                End If
            End If
        Next

        Response.Write(returnString)

What kind of ORM framework are you using? With SQL the DISTINCT keyword is used for this, that might help
