Call an aspx page in silverlight, without open it

Question

I have, in my silverlight application, a call to a aspx page, to create and register a txt file on a directory.

Uri ub = (new Uri(HtmlPage.Document.DocumentUri, "GenereInfos.aspx?&connexion=" + connexion + ";&id=" + this.Id));

        if (HtmlPage.IsPopupWindowAllowed)
        {
            HtmlPopupWindowOptions opt = new HtmlPopupWindowOptions();
            HtmlPage.PopupWindow(ub, "file", opt);
        }
        else
        {
            HtmlPage.Window.Navigate(ub);
        }

I have to go trough my aspx page to generate my txt file, because silverlight don't allow it.

The problem here is, a popup will appear, or the page will load the new uri.

What I want is call the code inside the asp only(which works perfectly), without loading the uri.

Is there a way to do this?

Edit : After DGibbs answer, there is another question now :

WShy can't I use GetResponse() in there?

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(new Uri
                     (HtmlPage.Document.DocumentUri, "GenereInfos.aspx?&connexion=" + connexion + ";&idPocedure=" + itmProcedure.IdProcedure));
            string response = new System.IO.StreamReader(req.GetResponse().GetResponseStream()).ReadToEnd();

Here a little answer : Silverlight is asynchrnous, so, we can't call GetResponse who is synchronous.

So, the best way to call my aspx page, is to use WebClient found here

On a local, but I can also choose a remote directory (using a string is my aspx). For the moment, I get the myDocuments folder to put my txt file on it. — provençal le breton, Jul 02 '13 at 14:48

Yes indeed, writing a txt file in my final goal. But, how do I retrieve my txt file ? Do not found isolated storage location... — provençal le breton, Jul 02 '13 at 15:16
Where will you host the ASPX page? It won't be able to just write a file to the client. — Alexander, Jul 03 '13 at 05:49
It is on server side of my silverlight application. And like I said, it alrady works, but I don't won't to open or load a new page with the document uri. — provençal le breton, Jul 03 '13 at 06:13

You could just use WebRequest:

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(new Uri
                     (HtmlPage.Document.DocumentUri, "GenereInfos.aspx?&connexion=" + connexion + ";&id=" + this.Id));
string response = new System.IO.StreamReader(req.GetResponse()
                 .GetResponseStream()).ReadToEnd();

This doesn't go trough my aspx page. – provençal le breton Jul 02 '13 at 15:13
I don't understand why I can't choose .GetResponse(), just have BeginGetResponse and EndGetResponse... – provençal le breton Jul 03 '13 at 07:03
Just find out the response : it seems that in silverlight, WebClient is better for those calls : http://social.msdn.microsoft.com/Forums/silverlight/en-US/4ff41b4f-df41-4dad-8e41-fa653cb05174/getresponse-doesnt-work-in-silverlight – provençal le breton Jul 03 '13 at 07:31
Well that was my original recommendation before the edit.. why couldn't you get it to work? – DGibbs Jul 03 '13 at 07:43
I don't know, it would'nt go trough it... I think that is it thanks to the completed method. – provençal le breton Jul 03 '13 at 07:52
