any page that I open in my browser comes up blank.
I don't get any errors, it just comes up blank.
I also noticed that it seems to bypass forms authentication. For example, even though the page I open is blank, it is the actual page name that shows up in the browzer instead of the page that it usually redirects to for the forms authentication.
I have upgraded web application from VS.2008 to vs 2010. I was using previously ReportViewer 2008 control in a page and replaced with 2010 ReportViewer Control.
I have installed the ReportViewer Redistributable also in my local pc as well as in the server. Also as per the new requirement I have placed the Scriptmanager in the web page where the reportviewer control located.
While running the page, the reportviewer run the report and is not showing the data on the screen. It shows the blank screen. But If I export the data to execl or world it is showing the data. Also the page numbers in the reportviewer showing the total pages available in the navigation bar. I am sure the report is running and bringing the data to the screen but not showing it.
I have designed menu using <ul> and <li> tags and handled onserverclick event, where redirection code is written. This code works fine for normal click. But when I right click on the link and select "Open link in new tab", it opens blank page. So how can I handle this scenario.
Following is the sample code,
<ul class="rounded-corners "> <li name="menuSample"><a onserverclick="lnk_clicked" runat="server" href="~/Sample.aspx" title="Sample">Sample</a></li>
</ul>
Server side code:
protected void lnk_clicked(object sender, EventArgs e)
{
strPage = (sender as System.Web.UI.HtmlControls.HtmlAnchor).Title.ToString();
Response.Redirect((sender as System.Web.UI.HtmlControls.HtmlAnchor).HRef);
}
I am using asp.net to call the reporting services report. In my asp.net page, there is a parameter screen which while running opns the reporting services report in asp.net page as pageA.aspx Now, whenever, I again change the parameters on the parameter page and click the run button, if pageA.aspx is already opened, it just refreshes that page but the page doesn't generate new results ( caused by the change in parameters). I want to close that page (pageA.aspx) before generating the same page with other values (caused by the change in parameters in parameter page). I want this function in page_load() function of the param page.

View 3 RepliesI am having an issue with displaying a PDF in an iframe in asp.net. When the pdf shows up it is showing up without the Acrobat toolbar that allows the user to zoom and print. This is causing a major hassle for our customers because they cannot read the PDF in the size that it is. If you try and set Acrobat to not show the PDF in the browser and browse to that page you get a message saying that it is trying to open it in Full Screen mode. how I can make it not do this from the code? Below is the code I use to stream the PDF to the browser:
Public Shared Sub StreamPdfToBrowser(ByVal doc As Document)
Dim Ctx As HttpContext = HttpContext.Current
'// Clear any part of this page that might have already been buffered for output.
Ctx.Response.Clear()
Ctx.Response.ClearHeaders()
'// Tell the browser this is a PDF document so it will use an appropriate viewer.
Ctx.Response.ContentType = doc.DisplayFileType
Ctx.Response.ContentType = "application/pdf"
Ctx.Response.AddHeader("content-type", "application/pdf")
'// IE & Acrobat seam to require "content-disposition" header being in the response. If you don't add it, the doc still works most of the time, but not always.
'// this makes a new window appear:
Response.AddHeader("content-disposition","attachment[inline]; filename=MyPDF.PDF");
Ctx.Response.AddHeader("Content-Length", doc.DisplayFile.Length)
Ctx.Response.AddHeader("Content-Disposition", "inline; filename=E-Sign Specification Report.pdf")
'// TODO: Added by KN to possibly fix UA issue
Ctx.Response.ContentType = "application/pdf"
Ctx.Response.AddHeader("content-type", "application/pdf")
'// Write the PDF stream out
Ctx.Response.BinaryWrite(doc.DisplayFile)
'// Send all buffered content to the client
Ctx.Response.End()
End Sub

We have this great asp.net web application that generates word documents (wordprocessingML) and saves them to the file system on the server. We are running IIS 6.0. I would like to know the best way to allow the user to click a link or something so they can open the document from the browser. I have been experimenting with the Microsoft.Office.Interop.Word object, but am getting an error when I try to active the application object. I don't know if using this object is the best approach or if I should be doing something else.

View 1 RepliesIs it possible to open a PDF always in a browser? That is no Download option will be provided by browser as a user will try to open that pdf file. My application is in ASP.NET (C#).
View 5 RepliesDeveloping a web application in C# which stores files in a tree structure in a server.
A project ( eg: ABC) has many sub folders (eg: ABC_sub1,ABC_Sub2...etc) . Each sub folder will have many types of files. (Eg: .dat,.txt .... etc)
I have stored the project name and the path to the parent folder ( in this case ABC) in a database.
Eg: \sereverNameTestMyProjectABC
What I need to do is when a user selects a given project ( eg; ABC) & clicks the link button component called "browse" to open the folder (\sereverNameTestMyProjectABC) in a new window.
This is the code I thought would work.
protected void LinkButtonFolderBorwse_Click(object sender, EventArgs e)
{
string myPath = @HiddenFieldFolderLocation.Value;
System.Diagnostics.Process prc = new System.Diagnostics.Process();
prc.StartInfo.FileName = myPath;
prc.Start();
}
HiddenFieldFolderLocation.Value gets the path of the parent folder (\sereverNameTestMyProjectABC).
When I click the link button nothing happens.

I need to open a second browser window or tab, but it must have a different session ID.
Opening the new browser window from an ASP.NET page is easy, but then it shares the same cookie and thus session ID with the original.

View 5 RepliesI have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}
