The following example shows how to wire up to ItemClicked event:
In HTML:
<ig:WebExplorerBar ID="WebExplorerBar1" runat="server">
<ClientEvents ItemClick="ItemClickHandler" />
<Groups>
<ig:ExplorerBarGroup Text="FirstGroup" Selected="true">
<Items>
<ig:ExplorerBarItem Text="FirstItem">
</ig:ExplorerBarItem>
</Items>
</ig:ExplorerBarGroup>
</Groups>

In C#:
this.WebExplorerBar1.ClientEvents.ItemClick = "ItemClickHandler";
In Javascript:
function ItemClickHandler(sender, args) {
alert("You clicked " + args.getExplorerBarItem().get_text());
}
