I have a gridview with hyperlink button in every row. Gridview is bind with some datasource.
Just what i want to do that when user click on hyperlink on particular row hyperlink button it should download a file.
The files are going to be saved daily in a share folder.
Secondly, I don't want to give user an option to open that file, means when user clicks hyperlink a dialog box should appear with open button.
how to find particular file as per date from share folder and download.

I tried this method:
string alteredname = "/store/" + filenames;
string filepath = Server.MapPath(alteredname);
FileInfo file = new FileInfo(filepath);
Response.AddHeader("Content-Disposition", "Attachment;FileName:" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "APPLICATION/OCTET-STREAM";
Response.Flush();
Response.TransmitFile(file.FullName);
Response.End();
but the downloaded file is losing extension. I am getting the file in the name of the page form which I am downloading.

I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.

I have a link button in my gridview. It is populating correctly; however, being I am populating the values in the gridview using "Eval()" method I don't know how to get the value of the selected Link Button (which is only selected by a user actually clicking
the Link Button).
The user can click on the text directly (instead of showing the "Select" auto created). I want to be able to capture the item they have clicked on's Text property.
Example:Column 1
Value1
Value2
Value3
When the click on "Value2" I want the text property to be stored in a string variable (In this case the text would be "Value2"). In the past I have captured this through GridView.SelectedValue; however, I am not using autopopulate selected button so I need to do this manually and I am unsure as to how I will do this.
Here is my code for HTML and I have not created any code for C# (I want to capture the item using C# in my Grd_Tables_SelectedIndexChanged Event)

I was following this tutorial and it worked perfectly: [URL] ....
I was wondering how do I archive this: the file name will be a link button (or whatever the best way is) and when click on the name, it will download the file (instead of haing an additonal "Download" column)?

here's the code so far:
[Code]....
[Code]....
mov is a quicktime file, my server has the mimetype: video/quicktime .......... but as I read, this code forces the save as download box which is exactly what i want :) now, here's the catch, i the file I am fetching is NOT on the physical path... it is on a completely different server:Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click
Response.Clear()
Response.ContentType = "x-msdownload"
Response.AppendHeader("Content-Disposition", ("attachment; filename=mydownload.mov"))
Response.TransmitFile("http://myOTHERserver.com/files/mydownload.mov")
Response.End()
End Sub
Obviously this doesn't work since TransmitFile requires that the file be on your physical path, so how do i do this? Someone said you must use the stream method. Do you have any sample code I could try? I've tried the HTTPStreamReader object but it's giving me issues, so I would love to find out if there is anyway this might work. Now here's some more important information: this are HUGE video files.. we are creating a downloads page... written in asp.net -- so you create an account using the .net membership class, then you select the file you want, go through a form where you enter your billing info and then after you pay a certain fee (this is already implemented), you go to your "downlaods" area in your account... there you have access to the files......... the reason i'm doing this is because i want to hide the download link, which will be something likehttp://myOTHERserver.com/2340987sdfkjhalsdlkjh23 ... (something really crazy)....... we don't want people seeing this on the status bar (Therefore hiding the download link is ESSENTIAL)........ the files are a good 500MB each approximately; so i would love to hear all of your suggestions as to making the streamreader work for me and how long would it take for the streamreader to READ the file........

I have a web application which consists of many aspx pages ... one of them shows a grid with rows that can be exported to a file via button click. This works fine. Now I want to have that feature which allows a user to access an external link to this page (or another) and to export to a file and download. I dont need any information on the page, just the file download. How could I do this also including security features like encryption?

Here is what I need to to. I have a gridview which I have a column that has a link to a pdf file on our file server. When I click the link I need to go into a database and update a column that they clicked the link then I need to open the file. by usinga HyperLinkField I am able to put in the link that I want to go to and when the page is running I can click on the link and it goes to the page and everything works fine except for being able to update the database part.
[Code]....
I tried using a ButtonField where in the code behind in the GridView1_RowCommand I pull out the file path and put it into a response write statement the problem I'm having with it is that when it opens the file it removes all the ""s so I get the error file cannot be found.
