how to open page in new tab with response.redirect or response.write
<p>I have a button event. At the end of the event I am redirecting to another page. But unable to open in new tab. </p>

<p>Giving compilation error - </p>

<blockquote>
  <p>newline in constant</p>
</blockquote>

<pre><code>//Response.Redirect("DeliveryChallanPrint1.aspx?val=" +this.txtPoNo.Text);

Response.Write("&lt;script&gt;");
Response.Write("window.open('DeliveryChallanPrint1.aspx?val="+this.txtPoNo.Text','_blank')");//error - newline in constant
Response.Write("&lt;/script&gt;");
</code></pre>
