.net - Hiding The Open Button When Doing A Response.WriteFile
Jan 29, 2010
Response.ContentType = "pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=test.pdf");
Response.WriteFile(this.txtFileName, true);
Response.Flush();
Response.End();
which shows a prompt to download the file and the prompt by default has "Open", "Save" and "Cancel" buttons with "Cancel" selected by default.Is it possible for me to hide the "Open" button and force users to eitehr save or cancel?

I have a button that calls a click event to download a picture. In my click event I have some code to change my display as the Save dialog pops up. The issue I am having is that when the dialog comes up it stops the previous line of code from executing. How can I check to see that my code has executed before calling the function?
Here is my button event handler and function:

how to write two files using Response.WriteFile?
I tried the following
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile);
Response.Flush();
Response.WriteFile(FilePath);
Response.End();
streamWriter2.WriteLine(CodeFileText);
streamWriter2.Close();
Response.AddHeader("Content-Disposition", "attachment; filename=" + textFile2);
Response.Flush();
Response.WriteFile(FilePath2);
Response.End();
But it downloads the first and stops.
It doesnot go for second one.

I've made a user control with several LinkButtons on it. On click of any of these buttons executing following code:
Response.ContentType = "Response.ContentType";
Response.AddHeader("Content-Disposition", "filename=" + CorrectFileName);
Response.WriteFile(filename);
Response.End();
And I have to problems with it:
1. after user click on one of the buttons another ones doesn't response
2. I need to execute some code after user received file (delete copy of it from the server)
I suppose I need to open another window and call SaveFile dialog from it. But how can exactly do this? I've found example code of opening window or starting SaveFile dialog but not two of them together and I can't figure out how to put them together...

I have an asp.net page.
Which is used to download files from server.
The page is using Response.WriteFile method to start download.
Every thing is working fine.
But download does not have resume support.
if I redirect user to that file without using Response.WriteFile method then it supports resume.

I've just installed VS 2010 RC and IIS7 with .NET framework 4.0 on a Windows 7 laptop (and I'm very new to this).
I'm trying to use Response.WriteFile to add a menu to an .aspx page, and it works but it also adds two square/unknown characters before the inserted text. Also, when I view the source of the displayed webpage in IE8, the source gets up to the point of the two squares, then shows an opening angle bracket (<) and then stops, although the rest of the webpage displays fine.
It doesn't matter whether the included file has any text in it or not, or whether it is an .html or .aspx file.
Response.Write doesn't have the problem.
(In FF and Opera, the inserted text is displayed as html code with a space (opera) or unknown character (FF) between each normal character. I'm not worried about those browsers as I'm developing soley for IE8)

I'm using an .ashx handler to retrieve an image file... It queries a local database, which retrieves the URL of an image which is hosted on Amazon S3.
But I can't use context.response.write(AmazonS3URL) because it returns the error '...is not a virtual path'.
Can context.response.write only return files that are on the local machine? Or is there another function to call remote files?

I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)

I have a drop down list that hides a panel with a bunch of controls when a certain value is selected, and shows the panel again when some other value is selected. This works fine. However it's slow when running both on my local webserver and on my web host, and takes about 1-2 seconds. What could be the reason for this? The only thing I do is to check which value is selected and hides/shows the panel.

if (!IsPostBack) {
ArrayList olist = new ArrayList() {"visible", "invisible", "visible", "visible", "visible", "invisible", "visible", "visible", "invisible"};
for (int i = 0; i <= olist.Count-1; i++) {

When the user clicks on "OPEN" button, It should open up that(.txt) file which is on the file server in ReadWrite Mode (like in notepad) without any Access Issues.
Or simply has to be openend as temporary READONLY .Txt File. So that the user can close after viewing it.

Here's my radiobuttonlist:
<asp:RadioButtonList ID="Pending" runat="server" AutoPostBack="True" OnSelectedIndexChanged="Populategrid">
<asp:ListItem Value="250">Over 250</asp:ListItem>
<asp:ListItem Value="300">Over 300</asp:ListItem>
<asp:ListItem Value="350">Over 350</asp:ListItem>
<asp:ListItem Value="400">Over 400</asp:ListItem>
</asp:RadioButtonList>
I have a gridview set up to bring in all of the items listed in the radiobuttonlist. When the page loads the first time it comes in as showing Over 250 only:
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False End Sub
This is the code behind:
Protected Sub PopulateGrid(ByVal sender As Object, ByVal e As EventArgs)
'Select Case Pending.SelectedItem.Value ' Case "300"
Dim conn As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("PendingClaimsConnectionString").ConnectionString)
Dim cmd As New Data.SqlClient.SqlCommand
[code]...
I'm getting an error under the If pending.selected value = "300" and .Parameters.AddWithValue etc...saying operator AND is not defined for types Boolean
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False End Sub0

First, I've taken the time to review this question which seems to be the most similar, however, the solution that seems to have been selected will not work in my scenario.Not to mention I worry about some of the comments claiming it to be brittle or an inadequate solution.
[URL]
-We have an XML document which basically contains all of the information for a Side menu.
-We have numerous URLS which are stored in a constants class.
-One of the elements in a string of XML (well call it label) is used to determine if the menu item is created as a LinkButton or a Label.
-Links use a custom user control that is used standard for all links across the application (why suggestion on similar thread doesn't work - I don't want all links to open in a new window - just one)
-One of the elements in a string of XML (well call it function) is used in a Switch statement to generate our links using Response Redirect.
It may look something like this.
[Code]....
Given this scenario, I'm trying to find the best way to quickly open a New Window, when a specific case in this switch statement is met. Can it be done with Response Redirect (this seems to be arguable - people say no it can't, yet other people say they have made it work)? If not, what alternative can work here?

How can I make a Response.Redirect open in a new page? I guess it would be the ASP.NET equivalent of <a href="page.aspx" target="_blank">click here</a>. I have a lot of code on an OnClick event handler and it redirects at the end of the code. It would make it very simple if there was a way to do it in ASP.NET.

I try to get parse JSON response for the following link:
https://graph.facebook.com/feed/?ids=135395949809348,149531474996&access_token=
The response is like that:
{
"135395949809348": {
"data": [
{
....Some data
}]
}
,
"325475509465": {
"data": [
{
....Some data......
}]
}
}
I use System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(string json) method.
But the objects key names always different , so I can't define the class that can be used for parsing this response.Is anyone has any experience in parsing multiple id's response from Facebook?

When I run the code below, nothing happens.
protected void Page_Load(object sender, EventArgs e)
{
System.IO.FileInfo file = new System.IO.FileInfo(Server.MapPath(Request.QueryString["path"].ToString()));
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.WriteFile(file.FullName);
Response.End();
}
The url of the page, is:
http://mysite.com/Lib/Rs/Download.aspx?path=/uploadedFiles/110210_CS_ADM-Coaching_SG_Final.pdf
If I add a param to the url and refresh, the file will load.
http://mysite.com/Lib/Rs/Download.aspx?path=/uploadedFiles/110210_CS_ADM-Coaching_SG_Final.pdf&ur=1223
Why wont the file load on the initial page load, or how do I get it to?

I was wondering how a page can keep the Accordion from refreshing it's selected index in a postback or when redirecting to itself. I wanted it to keep the index value of the last open page and somehow coax the accordion to have that open instead.
How would I go about that?

There are bunch of files stored in a DataBase as varbinary/image data. I am writing a program to extract these file data and send them to the browser so file can be opened or saved. My method is,
[code]....
BUT this method creates a file in the Server and then transmit to the browser. Means 100s of files will be created in the server when I open 100s of files with this process, naturally I want to avoid that.
Is it possible to do this without creating a copy of the file in the server ?
