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.
Is it possible to perform a file upload within an update panel.
View 2 Repliesi 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.
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.

I've got a DetailsView control with Edit and Update enabled. I'd like to write the edited record to an XML file after Editing. What's the best way to do this? I thought I could write to a text file and concatenate the db fields between XML tags but is there an "automatic" or best practice way to do it?

I have two sets of cascading drop down lists they are contained in a detailsview <edititemtemplate>. The problem is that when the user clicks update; the original data is wiped out and the user has to redo the selection of all items contained in a cascading dropdown even if the user didn't want to change that particular aspect of a record. If the user doesn't select everything an error is thrown by the stored procedure in regrds to null values not being valid.
Is there a way i can use cascadingdropdown so that the current values are visible when the user clicks update; meaning that they don't have to redo selections for all items involving drop down lists. The current selections would be default values.

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,

Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
