How to pass credentials when accessing SSRS report through URL - asp.net

Question

I am trying to access a SSRS report using URL like below
http://MyServerIP/ReportServer?/FolderName/ReportName&Param1=ParamValue&rs:Command=Render&rs:Format=HTML4.0&rc:Toolbar=false
When I try to access above Url, I am asked for my network credentials, giving which I get all pages of SSRS report rendered in browser window.
Now I want to display these contents in a popup window inside my webApp. For this I tried to make a jquery request and get contents, but doing this I get 401 unauthorized error. So I wanna know if there is a way to send credentials in jquery ajax get request.
As a turnaround I tried using below C# code to retrieve data, but it didn't helped either and gave same 401 error
WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password", "domain");
divContents.InnerText = client.DownloadString(my report path);
I am using SSRS 2008 R2 and my requirement is to show all pages of report in popup window. So all pointers in this direction are welcome.
Adding a point at last, my web app and report may or may not reside on same domain.
Thanks,
Ravi

What I would try:
Create a new page. On the C# side, use the ReportExecution2005 web service to render your report to HTML. Then pump the result out to the window.
In your pop-up, either call the new C# page via Ajax (to get the HTML) and inject the output into your jQuery window, or pop up the page itself as a separate browser window.
I can provide some sample code if you need it.
ETA: I found a possibly valuable piece of information:
This is from the HTML Device Settings page (emphasis mine):
Toolbar
Indicates whether to show or hide the toolbar. The default of this
parameter is true. If the value of this parameter is false, all
remaining options (except the document map) are ignored. If you omit
this parameter, the toolbar is automatically displayed for rendering
formats that support it.
The Report Viewer toolbar is rendered when you use URL access to
render a report. The toolbar is not rendered through the SOAP API.
However, the Toolbar device information setting affects the way that
the report is displayed when using the SOAP Render method. If the
value of this parameter is true when using SOAP to render to HTML,
only the first section of the report is rendered. If the value is
false, the entire HTML report is rendered as a single HTML page.

You pass the credentials like this in the query string:
dsu:DataSourceName=userName&dsp:DataSourceName=password
Replace the elements in bold with the values from your report, for example:
http://MyServerIP/ReportServer?/FolderName/ReportName&Param1=ParamValue&rs:Command=Render&rs:Format=HTML4.0&rc:Toolbar=false&dsu:Data=reportreader&dsp:Data=password1

You can use the Report Viewer control if you want to allow public access to secure reports without asking for credentials.
Create a new .aspx page and use the ReportViewer control like so:
<rsweb:ReportViewer ID="MainReportViewer" runat="server" BackColor="White"
Font-Names="Verdana" Font-Size="8pt" InteractiveDeviceInfos=" (Collection)"
ProcessingMode="Remote" ShowBackButton="False" ShowFindControls="False"
ShowPageNavigationControls="False" SizeToReportContent="True"
ToolBarItemBorderColor="White" ToolBarItemHoverBackColor="White"
WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Width="100%">
<ServerReport ReportServerUrl="" />
</rsweb:ReportViewer>
The code below can be used in the codebehind of your .aspx page to configure the report server, username and password, [etc..] in your Report Viewer
protected void Page_Init(Object sender, EventArgs e)
{
string UserName = ConfigurationManager.AppSettings["SsrsUserName"];
string Password = ConfigurationManager.AppSettings["SsrsPassword"];
string Domain = ConfigurationManager.AppSettings["SsrsDomain"];
string ReportServerRoot = ConfigurationManager.AppSettings["SsrsServerRoot"];
string ReportServerPath = ConfigurationManager.AppSettings["SsrsReportServerPath"];
MainReportViewer.ProcessingMode = ProcessingMode.Remote;
IReportServerCredentials irsc = new CustomReportCredentials(UserName, Password, Domain);
MainReportViewer.ServerReport.ReportServerCredentials = irsc;
MainReportViewer.ServerReport.ReportServerUrl = new Uri(ReportServerRoot);
MainReportViewer.ServerReport.ReportPath = ReportServerPath + "YourReportFileName";
}
