ListView...select programmatically

I have a ListView control and I want to programmatically select an Item inside the ListView and thus highlighting the Item too, just as if it was selected by mouse.

I suspect that i have to indicate the index of the Item but I don't know how to highlight the item in the box. Please help...

Thanks.

You need the listviewitem itself to use listview.items.indexof, you can't just search by name. To get the listviewitem you just loop through all listview items in the listview with a for each ... in ... next loop:

Code:

' there's a form with listview1 and button1 on it...
    Dim randomGenerator As New Random

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ListView1.View = View.Details
        ListView1.Columns.Add("Name", 100, HorizontalAlignment.Left)
        ListView1.MultiSelect = False
        For i As Integer = 0 To 15
            ListView1.Items.Add("Item " & i)
        Next
    End Sub


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

        Dim i As Integer = randomGenerator.Next(0, 16) ' search for a random item
        'loop through each item in the listview
        For Each lvi As ListViewItem In ListView1.Items()
            ' test to see if it is our item
            If lvi.Text = "Item " & i Then
                ' if it is then select it
                lvi.Selected = True
            Else
                ' if listview1.multiselect were = false then you could deselect any other selections here
            End If
        Next
        ' the button is selected so you wont see anything:
        ListView1.Select()

    End Sub
