Web Forms :: Read File From Sql Server Varbinary (max) Field?

Dec 20, 2010

I have a function that will take a file uploaded by a user of my system and store the contents of the file into a varbinary(max) field in a sql server database. I then display the filename of the file in a data grid for the user to see as a link button. When the user clicks on the link button, I want the file to be read from the database and served out to the user as a prompt to download the file. How can this be accomplished? The upload is fine, it is the download I can't figure out. Here is what I have so far.

[Code]....

I get the download to prompt, but it is showing the name of my .aspx page as the file to be downloaded.

Web Forms :: Load File From Database And Write A Response To Let User Download?

Mar 10, 2010

I am a newbie of asp.net.

The environment is .net 3.5 and C#.

There are files stored in sql server (datatype of column is varbinary in the database).

each record is in one record in that table (FILE_TABLE).

And there is another table (PATH_TABLE) to store the files paths.

for example,

when the user download the folder A (select an item on the tree and click a button on the client side),

there is one sub-folder B and two files A-1 and A-2.

in folder B, there is two files B-1 and B-2.

then, at the code behind (server), the server will get the files from the database and convert them (including the files and subfolders) to a .zip file (or other compressed files)

and then write a response (using the method HttpResponse.BinaryWrite(Byte[] xxx) )

to client side and let the user download.

after the download, the user can extract the compressed file and the structure of the folders and files keep unchanged.

AJAX :: Download File From Database Within A Update Panel?

Mar 3, 2011

I have struggled with this for the last 2-3 days. I have a tab container control with a update panel surrounding it. On one of the tabs I have allowed the user to upload and download files to a SQL Server database. The upload works fine and the download works fine only when I remove the update panel.

I have tried to implement the solution that's provided at the following location...http://encosia.com/2007/02/23/ajax-file-downloads-and-iframes/I had to modify the code a little bit to fit my scenario but it looks like it would work. Is there another way to download files from a database within a update panel?

If there isn't another way to do this what could be wrong with my code...following the example on the encosia site...

Page starting from [Code]....

The code never gets past the if statement with in this java script. Should I put a trigger on the update panel to force a post back. Any help will be appreciated, java script is not my strong point.

Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro.
