Using LinkButton PostbackUrl - new window/tab needed to open
<p>Im posting and redirecting to a third party by setting the PostBackUrl property on a LinkButton.</p>

<p>My problem is that I want this to open in a new tab but target="_blank" doesnt do anything here.</p>

<pre><code>&lt;asp:LinkButton ID="hlApplication" runat="server" Text="Start your application" aria-describedby="information" target="_blank" OnClientClick="this.disabled=true;" UseSubmitBehavior="false"/&gt;

hlApplication.PostbackUrl ="http://externalurl";
</code></pre>

<p>Any ideas how I can do this?</p>
