reselect ListBox1

Hi aplelois
What I understood from your question is that you want to reselect a selected item in a listbox via a button to reraise the ListBox_SelectedIndexChanged event. To acheive this the easiest way put the code you want to execute in the event in a seprate sub and call it from the event handler and from the button. The following code demonstrates the previous: Add a listbox and a button to a form and past the folowing code:


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim i As Integer
        Button1.Text = "Current"
        Button2.Text = "Previous"
        Button3.Text = "Next"

        For i = 1 To 10
            ListBox1.Items.Add(i)
        Next
    End Sub

    Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
        Listbox1Event()
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Listbox1Event()
    End Sub

    Private Sub Listbox1Event()
        Try
            MessageBox.Show(ListBox1.SelectedItem.ToString)
        Catch

        End Try
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Try
            ListBox1.SelectedIndex = ListBox1.SelectedIndex - 1
        Catch

        End Try
    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Try
            ListBox1.SelectedIndex = ListBox1.SelectedIndex + 1
        Catch

        End Try
    End Sub
