To accomplish this, you need two ASPX pages and a Crystal Report.

The first page is our "launch" page.  This can be a simple listing of reports with a button that will run the report, or it can be an advanced page where you collect report parameters.  Whatever you do, you will need some event to actually launch the report.  In my projects, I use a button labelled "Run Report". In the subroutine that handles the button's OnClick event, I assign any parameters to session variables or create a querystring, and use the following JavaScript to open a new browser window containing the viewer page:

Dim strPop As String = "< s c r i p t language='javascript'>" & vbCrLf _
& "window.open('viewpage.aspx','Report');" & vbCrLf _
& "< / s c r i p t >" & vbCrLf


Page.RegisterStartupScript("Pop", strPop)

The first part of this code creates a small JavaScript that will automatically open a new window containing viewerpage.aspx.  This method also has a second parameter, which is the name of the new window.  This name is not the title of the new page, but rather is used in the DOM hierarchy to call the new window for additional information, status or events, none of which we are doing, but you still need to name the window.  

In the example above, we are simply using the name "Report." You can edit the script to use a different window name assigned at runtime.  You will want to do this if you are opening more than one report from a launch page, since browsers will not open a second window with the same name as the one that is already open (and most browsers will replace the contents of the window).

The second part of the code above tells the ASP.NET engine to add a script to be executed when the page is loaded.  Keep in mind that the launch page will be reloaded in the client's browser after the postback, and this is what allows us to use a startup script to open a new window.

The View page should have all the code to render your report in its Page_Init.  If any parameters are used, they should be read from the session variables or querystring and passed to the report.  The View page can export reports and be used to navigate the report.

Remember on your Launch page to use If Not IsPostBack around your code that originally populates the page so you don't reset any user input.

Bonus Technique:
The window.open method can accept two more parameters.  One parameter is a string of key-value pairs that control the appearance of the new window.  You can turn off the address bar, set the height and width, etc.  A good reference for the window.open method can be found at http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/reference/methods/open_0.asp.

Double Bonus:
You can use this code snippet to open any type of file in a new window.  This technique is not limited to just Crystal Reports.

The problem with a link is getting the values from the settings page to the viewer page. You need some sort of postback, and the target on a link won't cause a postback.

I have a report in vs 2005.
The report runs a couple of steps away from a search.
The search finds customers by CustID.
CustID is stored in Session.
I want the report to run when a link is clicked.
It will use the CustID to execute the report.
I would like the report to open in a new window, but I don't like the idea of using javascript (accessibility issues).
What about the target attribute of the anchor tag?
I realise that it is deprecated, but I use Transitional DOCTYPE, so can still validate (I think).
How do you make the website map hold target attribute values.
This is killing me.
Cheers

When I tried this, it was blocked by Windows XP SP2. When I said to temporary allow blocked items, it stated it had to refresh, and then nothing happen. I got the original page back, not the new page containing the report.

Any suggestions.

When cutting and pasting the code, remember to remove the spaces between the letters in the 'script' tags. The spaces are there only so this CMS system will display the code properly.
