Popup after updatepanel postback is blocked by popup block
<p>I make a polling and want to popup the result immediately by window.open function after partial postback (updatepanel). But the popup is blocked by popup blocker. How can I fix it? </p>

<p>Here is my code:</p>

<pre><code>protected void btnPollingSubmit_OnClick (object sender, EventArgs e)
{
    UpdatePolling();
}

protected void UpdatePolling()
{
   // update the polling result
     ...
     ...

 ScriptManager.RegisterStartupScript(btnPollingSubmit, this.GetType(), "PollingResult", "window.open('polling-result.aspx','','width=200,height=100'), true);   

}
</code></pre>
