View 2 RepliesI have to implement an image upload functionality in asp.net. The method I have followed works like this :-
Submit a form containing an <input type='file'> element and set the target of the form to a named iframe[to give the impression of a Ajax request/response ]. The aspx file which this form is posted to, writes the image into the response as Reponse.Write("<img src='location'/>"); The image displayed is due for cropping (where i plan to use JCrop).
What I would like to know is : Is there another way to display the image in a <div> may be, rather than in an iframe which I think is far better than this approach.

View 13 RepliesI'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 1 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 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 :

View 3 RepliesI have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.
I am using Ajax to update my UpdatePanel every 1 second and it is working perfectly with my gridview. However, when I placed a image into the UpdatePanel, which it supposed be changing and updated every 1 second, it does not update but the gridview does. Gridview is getting active changing data from the database without any problem. The image which I want to see the updating is the StreamImage.jpg. StreamImage.jpg is inside my local directory. It only updates when I hit the refresh button.
