1. Opening a Hyperlink in a new window:
ASPX
<asp:HyperLink ID="jiraLink"
runat="server"> Click here to Expand Window </asp:HyperLink>
Code-behind:
String jiraURL = "http://" + jiraServerURL +"/jira/secure/IssueNavigator.jspa?sId=" + sessionGUID;
jiraLink.NavigateUrl = jiraURL;
jiraLink.Target = "_blank";
And, to automatically open a Hyperlink, put this in the Page_Load:
Response.Write("<script type='text/javascript'>window.open('" + serverURL+ "','_blank');</script>");
