AJAX :: Update Panel & Update Progress In User Control / Multiple Instances On Same Page

Feb 16, 2010

I have a user control, that has an update panel and update progress control in it.

I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?

Either way - how do I make it so that the update progress only displays for the proper user control?

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.

How To Let User Upload Multiple Images Without Pre-defining The Number Of HTML Upload Input Box

Nov 30, 2010

I'm looking for a way to have user upload as many images as they want (perhaps via drag and drop) or dynamically adding more upload box.I thought statically fixing (say 6) HTML upload input box is slightly limiting and the user have to click "Browse" button (6 times in this example) and navigating to the folder to pick the file.What is the best practice to achieve this so users find it easy to use? Perhaps with some AJAX magic?I also wouldn't mind having the user click "Upload more" to reveal (say 6 more) HTML upload input box.

How To Upload Multiple Images

Oct 4, 2010

i posted a problem few days ago

i was trying to upload images

after using the upload asp control

i save them into an array to upload them all at once this is working fine on the localhost but if the array contains more than 3 images on a different PC on the domain it gives me an exception

the exception "Cannot access a closed file"

i am saving my images in a folder in the same project and only the path in data base i do not know if that the best solution but i considered the performance that way will be better

i tried the solution mzmishra gave me

< httpRuntime maxRequestLength="10240" requestLengthDiskThreshold="4096"/ >

it did work and there is no more exceptions in different permition levels but in a permition level the images does not saved in the server so when i tried to view them there is no image to view.
