[RESOLVED] How to add autocomplete search to textbox from database field?

Hi…:wave:

I want to add autocomplete search feature to my application So when I type the first characters of the search key in the textbox, a drop list appear of suggested data from required field and the results list became lass as the entered characters match the search key “same idea of Google search toolbar”

The application created using: VB2008 & MS Access .mdb
Table name: store
Table field name for search: Item Part Number

This is my form search codes

Code:

---

Imports System.Data
Imports System.Data.OleDb


Public Class Form2
    Dim frm As New Form1
    Dim ConStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source =" & Application.StartupPath & "\data.mdb"
    Dim Conn As New OleDbConnection(ConStr)
    Dim DataSet1 As New DataSet
    Dim SQLstr As String
    Dim m As String


    Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click

        DataSet1 = New DataSet

        Static m As Integer = 0
        If tbSearch.Text = Trim("") Then Exit Sub
        ExactSearch()
        Conn.Open()
        Dim DataAdapter1 As New OleDbDataAdapter(SQLstr, Conn)
        DataAdapter1.Fill(DataSet1, "store")

        Conn.Close()
        tbSearchResulItemPartNumber.DataBindings.Clear()
        tbSearchResultItemDeascriptions.DataBindings.Clear()
        tbSearchResultItemLocation.DataBindings.Clear()

        tbSearchResulItemPartNumber.DataBindings.Add("Text", DataSet1, "store.Item Part Number")
        tbSearchResultItemDeascriptions.DataBindings.Add("Text", DataSet1, "store.Item Descriptions")
        tbSearchResultItemLocation.DataBindings.Add("Text", DataSet1, "store.Item Location")

        DataGridView1.DataSource = DataSet1
        DataGridView1.DataMember = "store"
        If Me.BindingContext(DataSet1, "store").Count = 0 Then
            MsgBox("No Result??!! ")
            Form1.Show()
            Me.Close()
        End If

        Exit Sub

    End Sub

    Public Sub ExactSearch()
        SQLstr = "SELECT * FROM store WHERE [Item Part Number ]= '" & tbSearch.Text & "'"
    End Sub

   
    Private Sub btnBACK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBACK.Click
        Me.Close()
        Form1.Show()
    End Sub

 
End Class

Kindly any suggested codes for adding autocomplete search...

Regards…:)

The TextBox class already has auto-complete functionality built in, if you'd care to look in the Properties window or read the MSDN documentation. You simply use a list that you populated from the database.

Thanks for advices I’ve try it but Unfortunately not working with my form :confused:

That screen shot has absolutely nothing to do with auto-complete. You have to set the AutoCompleteMode to whatever's appropriate, the AutoCompleteSource to CustomSource and then assign a StringCollection containing your list of values to the AutoCompleteCustomSource. That StringCollection must be populated from your database if that's where the acceptable values are stored. You did read the relevant MSDN documentation, didn't you?
