Set DrawMode with OwnerDrawFixed and handle DrawItem event.

Please give me details hits about it whether it on the textbox event handler or any other method or event i will use.

Please help me.

Add listbox and a textbox control onto the form.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        ListBox1.DrawMode = DrawMode.OwnerDrawVariable
        AddHandler ListBox1.DrawItem, AddressOf drawit
    End Sub
    Sub drawit(ByVal sender As Object, ByVal e As DrawItemEventArgs)

        If e.Index = ListBox1.SelectedIndex Then
            e.Graphics.DrawString(ListBox1.Items(e.Index), New Font("Arial", 10), Brushes.Red, e.Bounds.X, e.Bounds.Y)
            e.Graphics.DrawString(ListBox1.Items(e.Index), New Font("Arial", 10), Brushes.Black, e.Bounds.X, e.Bounds.Y)
        End If

    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        ListBox1.Text = TextBox1.Text
