AJAX :: File Upload Control In The Update Panel

Jul 1, 2010

I've been wrecking my brain on how to solve this but I'm all out of idea. I have a FileUpload control within an UpdatePanel. I have a button, let's call this btnSave, that saves the FileUpload.PostedFile into an sql server. What happens is that when the btnSave is clicked, I would save the file to a ViewState as well as upload it to the sql server. I also have an ImageButton, call this btnDel, that clears up the ViewState that holds the File in the viewState. This btnDel is an Asynchrounouspostback trigger to the UpdatePanel that holds the FileUpload control. If I browse a file, click on btnSave, everything would work fine. However, if I browse a file, click save, click on btnDel, browse anotherfile using FileUpload, and click save, sometimes FileUpload.PostedFile has a file and sometimes it is null. I'm really not sure what's causing this. I know that there is an issue of incompatibility if btnSave is made to be an asynchronouspostback trigger to the updatePanel. I don't see how making btnDel an asynchronouspostback trigger could affect this.

If I do take out the FileUpload control from the UpdatePanel and remove btnDel as a trigger, everything works fine except a postback is generated, which the client does not like.

AJAX :: Use A File Upload Inside An Update Panel Along With A Dropdownlist?

Jan 27, 2010

i m using an update panel on a page which contains a listview. the listview (in each row) has a fileupload control and a dropdownlist.

although both controls do not have any interrelated values, its a desgin constraint to use both of them inside a listview row (and hence ...n number of such rows)

everytime i change the selection in the dropdownlist, the file upload control clears.

i have been through this pos, which suggests putting the controls (which cause postback) inside an updatepanel (use AJAX) and keep the fileupload outside of ajax.

[URL]

however my problem is that both my controls are in ajax bound code (that is inside the update panel) and hence the selection clears the file in the fileupload control.

AJAX :: File Upload Control Not Working In Update Panel?

Feb 15, 2011

I have 3 upload controls ,one listbox and two button controls in page. One button control named Attach has the code to add the files to listbox form 3rd file upload control and the 2nd button control named Save has the code to save the files of 1st and 2nd file upload controls in application folder and items of listbox to database.

The issue is couldn't maintain the state of 1st and 2nd file upload controls after browsing the files to file upload controls and clicking on Attach button control to add file name to listbox which was browsed by 3rd file upload control.So i placed the 3rd file upload control, Attach button and listbox in update panel but its not working. My requirement is when clicked on save button files of 1st and 2nd file upload controls in application folder and items of listbox to database, but 1st and 2nd file upload controls will loose the files as soon as Attach button is clicked to add filename of 3rd fileupload control to listbox.

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.

AJAX :: Update Panel - Asp Panel Not Working Properly

When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.

I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
