I need to to export a file to the user. It takes 1-2 min to generate the file so I'd like to have the page go into a kind-of modal mode with a layover on the page and a 'Working' spinner showing. The problem is I can't make the modal stuff go away after Save File dialog is closed.
How can I remove the layover after the dialog is done?
I have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.

Is is possible to write to the http response stream from a dynamically created bitmap using the Response.Write/WriteFile without saving the image to the hard drive?

Even the anchor links aShow and aHide works in Firefox (I am using version 3.6.12) but for some weird reason I can't get the button controls to show/hide the divText. The exact problem is when I click the "Show Div" button I can actually see the dvText div for few milli seconds but then it dissappears. Is this a bug in Firefox or am I doing anything wrong I have no idea..
[Code]....
MemoryStream export = new MemoryStream();
iCalendarSerializer serializer = new iCalendarSerializer(iCal);
serializer.Serialize(export,System.Text.Encoding.UTF8);
return export;
so I am using the C# DDay.iCal library for exporting my calendars. Serialize takes in a "stream" so I passed it a memory stream. I now have a generic handler that calls the method that contains the above code.
public class CalendarHandler : IHttpHandler
{
private Calendar service;
private Membership membershipS;
public void ProcessRequest(HttpContext context)
{
service = new Calendar ();
membershipS = new Membership (null);
string userName = context.User.Identity.Name;
Guid userId = membershipS.GetUsersId(userName);
context.Response.ContentType = "text/calendar";
// calls the export calendar(the code that showed above that uses dDay ical.
var t = service.ExportCalendar(userId);
t.WriteTo(context.Response.OutputStream);
}
public bool IsReusable
{
get
{
return false;
}
}
}
So now I wrote the icalendar to the Outputstream. Now I have a jquery post that goes to this method and now I am not sure how to take the OutputStream result that the jquery post will get and make it popup with a save dialog box.
$('#ExportCalendar').click(function(e)
{
$.post('../Models/CalendarHandler.ashx', null, function(r)
{
});
return false;
});

I am having a great deal of difficulty getting a ModalPopupExtender to hide after I export a datatable to Excel.
If I simply rem out the Response.write in the code below, everything works correctly, but of course I don't get my excel sheet.
I have tried all kinds of ways to do this. Including calling a javascript function to hide it, wrapping the Panel in an updatePanel and placing the TransactionControl in a asp:PostBackTrigger.
All without affect. Anyone have a clue as to how to do this?
I was also hoping some event would fire after the ModalPopupExtender hides, but of course there is no such luck.

I changed an app so one of the edit screens opens as a pop-up window via showModalDialog. Previously everything was done in the same window and more back and forth navigation was required. The pop-up provides greater continuity. Unfortunately, as a pop-up, files will not stream to the desktop. If I bring up the page by entering a URL on the address line, so it is not a pop-up, files stream to the desktop OK.
Streaming a file to the desktop is done as follows:
[Code]....
This causes an open/save/cancel dialog to appear in the browser. Does anyone have an idea why a file cannot be streamed to a pop-up window? To get pop-ups to work I always include
[Code]....
in the header. That way I can open other pop-ups such as warnings and database error messages from a prvious pop-up.

I'm doing something for paypal.
So i have my values for paypal PDT like this:
[Code]....
and then i will send the form to paypal and get the values (i also need some javascript to do that but it's irelevant now).
[Code]....
So it works ok but it show me all the paypal values on the page.Logical since i do a response.write.
Now my question is if there is a way that i will not get to see the values on the page.
I've tried request.clear ,request.flush but i didn't come up with anything.
I have a modal pop up that I'm trying to hide after an insert has been performed. This is usually very easily accomplished by calling the hide() method. I have a close button in the same modal pop up that does this correctly. I can't seem to get this to work with another button or item inserted event of the data source or the data control though.

The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

I use ajaxToolkit:ModalPopupExtender to show a modal window panel. The panel among other things contains a "Submit" button. I would like to call a code behind function on Submit. First I tried this:
[Code]....
But btnSubmitOnHold_Click() is never called. Then I replaced OnClick="btnSubmitOnHold_Click" with OnClientClick="SubmitPutOnHold" and added
<script type="text/javascript">
function SubmitPutOnHold()
{
alert('blah');
}
</script>
This alert also never shows up. Finally, I tried
<ajaxToolkit:ModalPopupExtender ID="OnHoldModalPopupExtender" runat="server" TargetControlID="btnPutOnHold" PopupControlID="pnlOnHold" BackgroundCssClass="modalBackground" DropShadow="true" OkControlID="btnSubmitOnHold" CancelControlID="btnCancelOnHold"
OnOkScript="SubmitPutOnHold" >
</ajaxToolkit:ModalPopupExtender>
i have user control and in that i have ajax modalpopup extender now, i want to use this modal popup in my aspx.vb page like

I have populated my data using DataRepeater Control and i have a Delete button on that so each and every row has a delete button which allows user to delete a single entry from DB. I have put this control inside UpdatePanel so i can avoid full page postback.
When i delete the row from the database and try to show a alert message using Repsonse.Write it throws me the below error message
Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near 'itle||Untitled Page|<script language='ja'. Source File: [URL]
But, If i remove my update panel its coming up well, is there any solution so i can show alert box after a row been deleted ?
I have a webpart in a page in which there is a gridview(which shows list of customers). When I click on a link button in gridview, I would like to popup a JQuery modal window and fill the popup(this contains textboxes, then a gridview which contains mapped systems for thet customer, and another gridview which contains list of configured reports for that customer) with the details based on the customer name(link) clicked. Here I need to pass the customer Id and customer name parameters based on which I can fill the Jquery modal window.
pass parameters to JQuery modal window in order to fill the contents inside it?

I wrote an ASP.Net web page that will take a QueryString and stream a file to the client. The file is stored in a SQL Server database. Everything works great when I'm running the web site locally during development. When I run it in production from the server I can get a file through Firefox, but not Chrome. In Chrome I get Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error.See some other posts that mention this could be related to Content-Length, however, I can't understand why this would work in development and not production. For that reason I think there must be something else going on here.Here is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim Data_ID As String = Request.QueryString("Data_ID")
Using dt As New Enterprise_Error_Log.Field_FileDataTable

Here is the website situation:
Webpage A: look & feel alignments are in the central of the screen. It has a submit button. The last code in the submit command() is this message subject:
Response.Write(string.Format("<script>window.open('{0}', '_blank');</script>", url));
where url = another webpage B.The outcome is fine. Webpage B is populated properly. However, Webpage A postback as aligment to the left, it is no longer the center. I could not find a way to debug the issue.
