My Code

private void yourListView_SelectedIndexChanged(object sender, EventArgs e)
{
    if (yourListView.SelectedIndex == -1)
        return;
    //get selected row
    ListViewItem item = yourListView.Items[yourListView.SelectedIndex];
    //fill the text boxes
    textBoxID.Text = item.Text;
    textBoxName.Text = item.SubItems[0].Text;
    textBoxPhone.Text = item.SubItems[1].Text;
    textBoxLevel.Text = item.SubItems[2].Text;
}

Define "not working". Do you get a compile-time error, a run-time error, or does the actual behaviour not meet your expected behaviour. — RB.

Have you done any cut and paste with yourListView in the designer? If so, the event handler is not mapped any more to the SelectedIndexChanged event, unless you reassign it. — Alex Filipovici

just small proposal. you can set property FullRowSelect=true for your ListView :) — algreat

ListView doesn't have property SelectedIndex. You should use SelectedItems or SelectedIndices.

So you can use this:

private void yourListView_SelectedIndexChanged(object sender, EventArgs e)
{
    if (yourListView.SelectedItems.Count == 0)
        return;    

    ListViewItem item = yourListView.SelectedItems[0];
    //fill the text boxes
    textBoxID.Text = item.Text;
    textBoxName.Text = item.SubItems[0].Text;
    textBoxPhone.Text = item.SubItems[1].Text;
    textBoxLevel.Text = item.SubItems[2].Text;
}

I suggested here that property MultiSelect is set to false.

C# and WPF use this:

private void lv_yourListView_SelectedIndexChanged(object sender, EventArgs 
e)
{
    if (yourListView.SelectedItems.Count == 0)
        return;    

     var item = lvb_listInvoices.SelectedItems[0];
     var myColumnData = item.someField; //use whatever you want
}

Can you provide an explanation of the changes you made?

you should always try and use 'var' keyword, since you are working with objects
