AJAX :: Update A Movie Picture Using File Upload Control With Updatepanel
Mar 20, 2010
im trying to update a movie picture using file upload control that is located under an update panel but nothing seems to get updated, is there anyway that the update panel is giving me this mess cuz i have tryd everything nothing seems to work only if its with an update panel ..
am trying to use the AsyncFileUpload control in ajax toolkit to upload a picture file, save the file on a location on the server's filesystem and display the picture file back to the client system. I have both the image and AsyncFileUpload controls inside an updatepanel but its seems the UploadedComplete server code is not firing when the file upload completes any clue?
I want to add picture to my SQL database using file Upload control but I don't know which attribute should I use also I don't know how to add it in the stored procedure,
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.
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 am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.
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,
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.
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.
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.
This sounds weird, but I would like to NOT update a control that's within an update panel. Is this possible? basically the way facebook works, facebook controls are rendered on a "get" command. but I have controls within the same update panel that cause AJAX postbacks. When the postback's happen, I lose my facebook server-side controls. I am wondering if I can "unregister" a control from an update panel? Or do I just have to redesign that page.
I have a detailsView inside the update panel., and in the detailsView I have a FileUpload Control and a button btn_Upload. In the click event I have written code :
I have an asp.net panel having various controls including gridview. I have converted this panel into pdf and attached it as an email attachment using memory stream. Everything is working fine. Now I have an File upload control outside panel through which I have to attach a file and send it in mail along with the already attached panel. But I am unable to figure out how to do it.
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.

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.
my application is running in visual studio 2005, i used ajax control toolkit for .Net framework 2.0.but now i want to use ajaxcontroltoolkit latest version which is for .net framework 3.5 in my application which is running on .net framework 2.0 and visual studio 2005.how to integrate or use ajaxcontrol toolkit ?because i have some functionality like there is one file upload control and when click button it will take 2 to 3 min for upload so i need progress bar with loading gif file.because of asynchronous postback fileupload control has not file.so i must assign postback trigger to button if i assign postback trigger to button than loading gif or progress bar not working.so i want to use AsynchFileUpload control of newly release toolkit.
is there any way to do it? or any other way.my client also not want to switch over it's application from 2005 to 2008.My code is below
i am new to this ASP.NET and AJAX.I am trying to learn AJAX. I Have one doubt.what is the difference between normal file upload control and ajax AsyncFileUpload Control ..?
