View 3 RepliesI 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 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.

View 4 RepliesI am fixing issues in a project where I was not able to figure out a solution for the below problem. There are multiple user controls in Main.aspx page. First one is header.ascx which is added directly in .aspx page. and the others are added dynamically from Page_Init event. Basing on the hyperlink clicked from the menu on the left side of the main page, the respective user control is displayed.
Now, If I try to add script-manager/update panel inside any of the dynamic user controls, the respective user control page throws error. I have noticed that the header.ascx control is using scriptmanager. Is it creating the problem? How to handle this kind of issue?

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.

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.
