How do I launch a new window in ASP.NET

I have several web apps that I want to redirect to a new page, but have that page open in a new browser window. The basic scenario is that I have a CrystalReport object that gets created and displayed on-screen as a .PDF stream. I need to have this page launch in it's own window leaving the first browser alone

Here's the code I'm using to launch the report

Private Sub btnPrintList_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrintList.Clic
'Set up and fill the DataSe
Me.DsCalendar1.calMonthlyItems.Clear(
Me.daMonthlyItems.SelectCommand.Parameters("@tStartDate").Value = Me.Calendar1.VisibleDat
Me.daMonthlyItems.SelectCommand.Parameters("@tEndDate").Value = Me.Calendar1.VisibleDate.AddMonths(1).AddDays(-1
Me.daMonthlyItems.Fill(Me.DsCalendar1
'Populate and create the repor
Dim crReport As New EventLis
crReport.SetDataSource(DsCalendar1
'Convert the report to a PDF strea
Dim strStream As New System.IO.BinaryReader(crReport.ExportToStream(CrystalDecisions.[Shared].ExportFormatType.PortableDocFormat)
'Display the PDF content in the browser. Here's where I'd like the system to launch a new browser
Response.ClearContent(
Response.ClearHeaders(
Response.ContentType = "application/pdf
Response.BinaryWrite(strStream.ReadBytes(strStream.BaseStream.Length)
Response.Flush(
Response.Close(
End Su

Thanks
 
The only way to launch a new browser window is on the client side, using
JavaScript's window.open() method (well, you can do it with a link and a
target frame, but you have much less control, but in either case you have to
do it on the client, not on the server). What you can do on the server is to
dynamically create the script to open the new window and add it to the Page
using RegisterStartupScript().

You can use Javascript for that.
Here...
if(IsPostBack)
{
start = StartDate.Value;
end = EndDate.Value;
if (strAdmin == "1")
{
surl = "AirTrans.aspx?start="+start+"&end="+end+"&section="+section+"&soc="+lblCompany;

}
else
{
surl = "AirTrans.aspx?start="+start+"&end="+end+"&section="+section;
}
features = "width=700, height=600, location=no, menubar=no,
status=no, toolbar=no, scrollbars=yes, resizable=yes";


script = "<script language = javascript> window.open(' " + surl +
" ','',' " + features + " ');</script>";
Response.Write(script);
lblStatus.Text = "Your Search is being carried out. The results
will open in a new browser window. You can search again using the
following form.";


}
HTH!
