i have a combobox that contains the items 0001,0002,0003, etc. i have a listview with 3 columns namely ID, Name , Age. I want to do is when i select the ID "0001" in the combobox, it will display the name and the age in the textbox1 and textbox2 that is from the listview . Thank you

Try something like this:

For Each lviItem As ListViewItem In ListView1.Items
    If lviItem.Text = ComboBox1.Text Then
        TextBox1.Text = lviItem.SubItems(0).Text
        TextBox2.Text = lviItem.SubItems(1).Text
    End If
Next

Same, except I'd add "Exit For" after line 4.

If you set the Name property of each item when you add the items to the ListView then you don't have to do a search. You can access by key as in

Private Sub ComboBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

    Dim key As String = DirectCast(sender, ComboBox).Text

    If ListView2.Items.ContainsKey(key) Then
        txtName.Text = ListView2.Items(key).SubItems(1).Text
        txtAge.Text = ListView2.Items(key).SubItems(2).Text
    End If

End Sub

An example of adding with keys is

item = New ListViewItem({"0001", "George", "42"})
item.Name = item.SubItems(0).Text
ListView2.Items.Add(item)
For Each lviItem As ListViewItem In ListView1.Items
    If lviItem.Text = ComboBox1.Text Then
        TextBox1.Text = lviItem.SubItems(0).Text
        TextBox2.Text = lviItem.SubItems(1).Text
    End If

wher i put this code sir? i'll try to put it in the combobx Private Sub ComboBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

but it is not working . thanks
