Upload file control intefering with javacript and Sys.WebForms.PageRequestManager.getInstance?

Posted By:      Posted Date: August 30, 2010    Points: 0   Category :ASP.Net
Ok I'm trying to use the dreaded Upload File control and it's not within an UpdatePanel. Here's what I have, I'm using jQuery to display messages on the client side from the server. One of the things I'm doing is I'm setting up a script to run using: Sys.WebForms.PageRequestManager.getInstance().add_endRequest(iamloading); and in my iamloading I have: function imaloading() {    $(document).ready(function () {        displayMessage();    }) } Not to bore you with details but the displayMessage is where I am doing the jQuery, this has worked for ever.Now I'm building this page with the Uploadfile control and this stops working and if I remove the control it works again.I've made sure that the function handler is created for iamloading but it never fires as though something has unregistered the event. Any help or suggestion would be of great healp.Thanks

ASP:Upload control . Uploading into a SharePoint Document Library Subfolder and FILE NOT FOUND error

RE: ASP:Upload control . Uploading into a SharePoint Document Library Subfolder and FILE NOT FOUND error Two Issues, apparently unrelated. I have subfolders like this /ApplicantDocuments/20 and /ApplicantDocuments/21 (where 20 and 21 are my subfolders and ApplicantDocuments is my library. 1. The below function is erroring with file not found, but I confirmed I'm sending the fully qualify path (i.e c:\test.txt) to System.IO.FileStream content = System.IO.File.Open(documentFileName, System.IO.FileMode.Open); 2. Even if it worked, looking at the code, I'm not using argument foldername.  I'm passing 20 to the argument. How can I make sure it uploads into subfolder 20 of ApplicantDocuments? Thank you.     Just testing in test environment. Will tighten code once it works.   public void UploadDocumentToSite(string foldername, string documentFileName) {      SPSite siteCollection = new SPSite("https://xxxxxx");      SPWeb web = siteCollection.OpenWeb();      //SPSite.AllowUnsafeUpdates = true;      //Web.AllowUnsafeUpdates = true;      string Lib = "ApplicantDocuments";      SPFolder destFolder = web.GetFolder(Lib);      sendmail(documentFileName+" "+foldername);

Uploading .pdf files with FIle Upload control and then saving to database


Hi everyone!

I'd like to allow users to upload a .pdf file via the file upload control (if that's the best method), save the file to the db and then retrieve it so they can click on a link and open the .pdf they've uploaded.

I've been looking for a tutorial on how to do this but keep running into methods of saving the file directly on the server in a directory, not in SQL server  (using Linq and VB by the way)

Can someone please point me in the right direction on how to do this?   Thanks!
