AJAX :: How To Initiate A File Download From Withing UpdatePanel
Aug 31, 2010
[Code]....
I'm building dynamically a series of ImageButton controls, and I want to assign them a hyperlink for downloading files.So say you got a dropdownlist of 3 items 1,2 and 3, if you select 1 it creates one imagebutton and pointrs to fileA, if you select 2 it creates two imagebuttons and the first one points to fileA and the second one to fileB and so on...Everything is wrapped in an UpdatePanel to avoid postbacks.I have a problem binding the download link in the ImageButton.navigateurl, and then downloading it. I don't know how to do it...
I have a few app settings I want to update from within my web site and to do this I use this code:
[Code]....
This works fine in my development enviroment but when using IIS7 I get an exception while saving these settings:Access to the path 'C:InetpubwwwrootNSiteCOMweb.config' is denied.How can I configure IIS7 to allow my application to update web.config?
How can I work with Download functionality with Updatepanel. Here I am placing download code.
string fileName = Convert.ToString(e.CommandArgument); if (fileName != "") {
[code]...
I am calling this function from a Grid in Updatepanel. When I click on Download image in a grid column, no action is taking place. Plz find a solutions for me.
I'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,
hat's the best way to allow a user to pull down an RDP file, but to do so using AJAX? In other words, I have a hyperlink and I need an RDP file to be downloaded by the user, but without a full page refresh.
I tried to make an AJAX call using the following example for RDP. It seems to work on Chrome and Firefox, but not on any version of IE.
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.
I have very similar problem as this: Allowing users to download files - ASP.NET , but in my case I am generating xlsx file with ajax, and on ajax-called aspx page I am using:
[code]....
When this file is generated, control is returned to ajax calling page and from there I wan't to show save file dialog based on this ajax response and allow user to download this generated file. I don't want to save file on disk with ajax called page and then redirect ajax calling page to that file, because of popup blocker in IE. I am using jquery for ajax calls:
I want to use Ajax File Upload control from toolkit. This control begin to upload the file as soon as i select from the browse dialogue box. But what i want is, I want that upload start when i click on submit button.
have found many solution for my issue but none doesn't work in my scenario. I have created a test project to demo my concept.Basically, there is a page that host a user control...
[Code]....
WebUserControl1 has a dropdownlist and two other webusercontrols (to be displayed based on the selection of dropdownlist element) inside updatepanel as below.
[Code]....
Code behind file for WebUserControl1 is .....
[Code]....
Now, the problem starts here...There is an external javascript file [JScript1.js] (embedded resource) which basically is used to display an alert box.
[Code]....
WebUserControl2.ascx.cs code behind is
[Code]....
Alert window doesn't get displayed when I change the dropdownlist value. Even the script is getting registered three times (look in the firebug) Need to use ScriptInclude instead of ScriptBlock as the original JS file is too big.
I am exporting a datatable to an excel sheet. When the ExportToExcel event is fire it pops up a "file download dialog" asking if I want to open or save. What I want to do is right after user clicks on open, or save I would like to show a modal popup saying "Do you want to finalize this download?".
Here is some code, it all works except it won't show modal popup after exporting to excel. Why won't mpeFinalizeDownload.Show() run unless I comment out the line above it?
I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?
I currently have an asp.net page which a loggd in user goes to and theres a bunch of dynamically generated links to zip files that he or she owns and can downloads.Currently they click download and I have no way of knowing if it completes succesfully etc so can't log it. I do log the attempt.Is there are good download manager or solution I can use so they will have progress bars on the site, they can queue multiple ones up and most importantly I can track failed and successful downloads.
I am trying to use a linq query to create a report and I am unclear on how to traverse the linq dataquery in my case. Inside my for each loop, i have a do while loop. The way it is written below, the do while loop is infinite because I never skip to the next itm in oneSchedule. Placing a Next inside the do while loop causes a syntax error. So what is the correct method for moving to the next itm within the loop?????
I want to upload a file INSIDE an updatepanel using the asyncfileupload control. But in the code below the filename is EMPTY! Why?
Protected Sub dvTicketDetail_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdateEventArgs) Handles dvTicketDetail.ItemUpdating Dim afupload As AjaxControlToolkit.AsyncFileUpload = CType(dvTicketDetail.FindControl("afuFlyerEdit"), AjaxControlToolkit.AsyncFileUpload) 'only upload physical file if fileupload control is NOT empty If afupload.FileName <> "" Then 'a new file must be assigned to record End If End Sub
I have a wep page. Its consists of some controls along fileupload controls. My page Fully placed into UpdatePanel. when i press the submit all contols values and file upload file should be stored into back end.i used vs2008 framework 3.5.
Note: for fileUploading perpose i should write trigger with postback on submit button.while processing the submit button action i want to show some processing (progressing) controls like round rotation like..shall i place on ajax toolkit 4.0 instead of 3.5.
This action has a pretty high likelyhood of throwing an exception (or at least not being able to return the file).
Due to the nature of the application (which contains a lot of dynamic content), I can't really redirect to an error page in this situation. The current page needs to stay open somehow.
So I'm ideally looking for something like a javascript pop-up, but afaik this isn't going to be possible since I don't know any way to return a javacript instruction in a non-ajaxed controller call. If I display an error page I need to force it to open in a new window some how. Is there any possible solution to this problem?
