Subscribe to the lb.SelectedIndexChanged event.

tabpage tp = new tabpage;
form2.tabcontrol.tabpage.add(tp)
Listbox lb = new Listbox;
lb.SelectedIndexChanged += new EventHandler(lb_SelectedIndexChanged);
tp.controls.add(lb);

Once an item is clicked, you can get the selected indexes (or index):

<br />
void lb_SelectedIndexChanged(object sender, EventArgs e)<br />
{<br />
<pre><br />
    ListBox lb = sender as ListBox;<br />
    int selectedIndex = lb.SelectedIndex;<br />
    //For multiple selections<br />
    System.Windows.Forms.ListBox.SelectedIndexCollection   <br />
    selectedCollection = lb.SelectedIndices;<br />
</pre><br />
}<br />
<br />
