AJAX :: Downloading File And Setting Its Date Modified Attribute?

Feb 8, 2011

Is it possible to download a file and set its Date Modified attribute by means of Ajax? I tried to use server-side code below but couldn't set Date Modified although I explicitly used "Last-Modified" Response header:

try{
Response.Clear();
Response.AppendHeader("Content-Disposition", "attachment; filename="+l_attchmntFileSpec);
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Last-Modified", "Tue, 15 Nov 2010 12:45:26 GMT");
Response.BinaryWrite(l_attchmntToDownload);
Response.End();
}
catch (Exception Ex)
{ ...
}

Note: The file in question is stored in my database. It is represented by byte array l_attchmntToDownload.

Sort Datatable / Dataview / Gridview Of Files Based On File Modified Date?

Aug 2, 2010

I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.

I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).

If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?

C# - Retrieve "Last Modified Date" Of Uploaded File?

Mar 3, 2011

I am developing a website, in which client uploads some document files like doc, docx, htm, html, txt, pdf etc. I want to retrieve last modified date of an uploaded file. I have created one handler(.ashx) which does the job of saving the files.

Following is the code:

HttpPostedFile file = context.Request.Files[i];
string fileName = file.FileName;
file.SaveAs(Path.Combine(uploadPath, filename));

As you can see, its very simple to save the file using file.SaveAs() method. But this HttpPostedFile class is not exposing any property to retrieve last modified date of file.

how to retrieve last modified date of file before saving it to hard disk?

C# - Gridview Attribute Modified By Javascript Is Lost On Postback?

Sep 10, 2010

I have a gridview control that extends the default gridview. I have added an attribute called "hiddenSelectedValues" to to the gridview during the "PreRender" event and I have a private variable that points to the value of that attribute.I have some javascript code that modifies the value of this attribute based on the user checking or unchecking checkboxes in the grid. I have confirmed that the javascript is indeed modifying the value of the "hiddenSelectedValues" attribute by using Firebug to see the change as it happens.

However, once a postback occurs, the grid looses the updated value of this attribute and I am unable to reference get the updated value on the server side.How do I keep the value of an attribute changed by javascript on postback?

AJAX :: Downloading A File And Updateprogress?

Apr 22, 2010

I have an export to excel functionality on my web application. WHen the user clicks the "Export to Excel" button, the file is created and it will ask the user to open it or save it to their local machine.

Since the file creation process takes a long time, I added the ajax update progress control. SO now, as soon as the user clicks the "Export to Excel" button, the progress bar image shows up, but after the file is created, I get the following error.

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

I know that, if we use Response.write in the code behind, we get this error. But I have to use Response.Write because I am presenting the user with a prompt to save or open the newly created file. Is there any other way to do this?

The following is the aspx code.

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>

JQuery :: Modified ListBox Not Posting Back Modified Values?

Aug 27, 2010

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:

$("#MyList_btnAddAll").click(function(e) {
e.preventDefault();
$('#MyList_lstAll option').appendTo('#MyList_lstSelected');
});

The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.

The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.

I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?

Web Forms :: Setting Visible Attribute On PlaceHolder Control Triggers?

Feb 22, 2011

I have a web form with an Asp.net PlaceHolder control. By default the control is set to visible false and will be displayed through the code behind based on several criteria. In general this PlaceHolder control wraps several other Asp.net controls. Now a new requirement ask that the controls within the PlaceHolder control be visible at all times an no longer hidden. So in the Aspx code I changed the laceHolder attribute and set it to visible. Now all kinds of Java Script validation errors are occuring and it is a horrible spahgetti code nightmare. Is their a way to set the visible attribute on the control and not have it trigger the validation?

Web Forms :: Downloading A File - File Name Is Shown Incorrectly On Opening

Apr 21, 2010

we are working on a file download page. We want to download a file with a name with spaces and accents. Although the filename is shown correctly on the filedownload dialog, when we click open, the file name is shown with %e1%ba%a3n%20... on notepad. ('Save as' shows the correct name) This problem only happens in Internet Explorer.

Is there anyway we can Display the file name correctly (on the target application) after opening it (without saving) from file download dialog ?

We use this code to set the filename :

fileName = Server.UrlPathEncode(fileName);
Response.AppendHeader("Content-Disposition", "attachment; filename="" + fileName + """);

Configuration :: Modified .vb File Not Applied After Rebuild?

Oct 19, 2010

I recently purchased the source code of an existing DotNetNuke module in order to make a few modifications. The source of the module contains various .ascx, ascx.resx and .ascx.vb files. as well as a main.dll file. Lets call them:

myfile.ascx
myfile.ascx.resx
myfile.ascx.vb
myfile.dll

I'm using Visual Studio 2008 PRO.

I've made a few changes to "myfile.ascx.vb". When I rebuild "my_module" via Build --> Rebuild my_module, I get confirmation that there are no errors in the Error List. I then upload a fresh copy of "mydll.dll" from the "/obj/release/" folder on my local machine up to the "/bin/" folder on my DotNetNuke site.

The issue that I'm having is that the changes that I made to "myfile.ascx.vb" are not appearing on my DotNetNuke site. Are there additional files that need to uploaded? I've checked timestamps on all of my local files and the only files that are updated after the build is "mydll.dll".

Downloading A File From Outside The Webroot?

Jul 15, 2010

I'm trying to write come code for users to download files, but the files are located above the webroot (e.g. c:downloads)

I've found some code online that allows me to download a file via a url parameter/argument which is perfect, but the files need to be located within the website structure.

<%@ Page language="vb" runat="server" explicit="true" strict="true" %><script language="vb" runat="server">Sub Page_Load(Sender As Object, E As EventArgs)Dim strRequest As String = Request.QueryString("file") '-- if something was passed to the file querystringIf strRequest <> "" Then 'get absolute path of the fileDim path As String = Server.MapPath(strRequest) 'get file object as FileInfoDim file As System.IO.FileInfo = New System.IO.FileInfo(path) '-- if the file exists on the serverIf file.Exists Then 'set appropriate headersResponse.Clear()Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)Response.AddHeader("Content-Length", file.Length.ToString())Response.ContentType = "application/octet-stream"Response.WriteFile(file.FullName)Response.End 'if file does not existElseResponse.Write("This file does not exist.")End If 'nothing in the URL as HTTP GETElseResponse.Write("Please provide a file to download.")End IfEnd Sub</script>
Source: http://www.xefteri.com/articles/show.cfm?id=8

how this can be modified so that it can access files outside the webroot?

I'd like it so that I can create an href like: <a href="download.aspx?file=test.pdf">Download File</a> and then the code will download the file from c:downloads est.pdf
