Web Forms :: How To Display The Uploaded Image On The Webpage
Aug 22, 2010
Does anyone know how to display the uploaded image onto the webpage after the image has been uploaded via the asyncfileupload control?
I tried setting the value of an imageurl property of an image control within the OnUploadComplete event however it seems the code 1st refreshes the page, runs through the Page_Load event, then finally the OnUploadComplete, so I'm assuming since it's run last, this is why it doesn't display the imageurl.
i want to load image into image control emmidiatly when i am uploading it by using fileupload control that means when i am uploading a file i display on the page immediately on page in image control.
I have an asyncfileupload control. AFTER the file has been successfully saved to disk I want to assign the uploaded image to a HTML element. To show it to the user.
Important: in the afuFlyer_UploadedComplete method I'm renaming the image, so the image saved to disk does NOT have the same name as the file the user initially uploaded.
function Async_UploadComplete(sender, args) { var filename = args.get_fileName(); var contentType = args.get_contentType(); var text = "Size of " + filename + " is " + args.get_length() + " bytes"; document.getElementById('lblStatus').innerText = text; }
But the args.get_fileName(); is useless since the filename has been changed. So I need to pass the new filename to this method somehow? Also, is the image actually already saved to disk when the Async_UploadComplete function is called? Or has the upload to the server just been completed and not the saving to server disk?
Ive also tried working with ScriptManager.RegisterClientScriptBlock and ScriptManager.RegisterStartupScript in afuFlyer_UploadedComplete method without success:
I want to display an image on a page with Image control on it.
I know this is very simple but tweak in my case is that image is available as a stream variable (which I am getting as a response from one of the server) instead of physical file.
Eventually I want to create a control for this with some other feature on it.
My question is how to assign "stream" variable to Image control?
i did this code to upload file and displaying it in the image:
[Code]....
the code works good. the file is uploaded under my website here in the solution explorer: now after uploading the file,the newly uploaded file is shown in the image(since there were a few more images present in the same location but they were not shown by the image) i used this url to the imageurl:
ResolveUrl("~")
which returns me this:
WebSite1
now my question is why the newly uploaded image is shown in the image? there were several other images present at the same location and even i have not used something in my code that tells to show only the newly added image from my website into the image.
I am trying to put together a page where files uploaded by a specific users would be listed in a bulletedlist and I am stuck. Here's the rundown:
Users login, they upload files which are saved to disk in the user's own directory. All the file's information, including the path, is stored in a SQL database.
The user has also its own page, where there is a bulletedlist (set as a hyperlink) that gets the filename from the SQL. However, the path to the file is incomplete.
The file is saved to the site's directory structure: C:WebsitesSiteUploadsUserFile.pdf. However, the hyperlink shows[URL]
Can anyone point me to the right direction? Below is a snippet of the upload method and the retrieval to build the bulletedlist.
I am trying to make a photo gallery. I want to save the uploaded image to data base ...the article below at " Display image after upload without page refresh or postback using ASP.Net AsyncFileUpload Control" shows how to show the uploaded image.. How to save the image in SQl Database?
I do not know how to do it.. Can the code be modified..?

I am using fileuplaod control for uplaoding images. I want to change the aspect ratio of my image. Say 4:3 for horizontal pictures and 3:4 for the vertical images. How to do that in Asp.net
I am using a fileupload tool and an asp button. I want to upload image using fileupload, save it in a folder named images in my website and create its thumbnail view on the same page using VB.
Below is the code for "Upload" button when uploading any file:
if (contenttype != String.Empty) { if (File.Exists(Server.MapPath("~/Folder/'" + Txt.Text + "'/") + filename)) { LMsg.Visible = true; LMsg.ForeColor = Color.Red; LMsg.Text = "File name '" + filename + "' already exist. Please change the File name to save this file";
[Code] ....
File upload control allows maximum file size is 4MB. If file size increase to 4MB it shows error page like "the page can not displayed".
I want to increase the size of uploaded files to max 10 MB not more than that. If file size increase to 10MB, it should show message.
I've got to following function which is called to change the resolution of an image. I want to do this so uploaded image with for example 300dpi will be modified to 72dpi (for web). This question is related to another question here on SO where i'm working on.
I'm creation an extension method for this to be able to use this function on more places in my application, instead of only when uploading new files. (See above mentioned question)
public static byte[] SetDpiTo72(this byte[] imageToFit, string mimeType, Size newSize) { using (MemoryStream memoryStream = new MemoryStream(), newMemoryStream = new MemoryStream()) { memoryStream.Write(imageToFit, 0, imageToFit.Length);
I have code that is successfully uploading images to a folder on my website with the code below.. what I would need to do next to actually display that image on the same .aspx just after the actual upload?
Private Sub btnUpload_Click(ByVal sender As Object, _ByVal e As System.EventArgs) Handles btnUpload.Click Dim destDir As String = Server.MapPath("./images/Upload") Dim fName As String = Path.GetFileName(uplPicture.PostedFile.FileName) Dim destPath As String = Path.Combine(destDir, fName)True lblUploadSuccessful.Text = "Upload succeeded." End Sub
I 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.

Question one: Once i upload the file and i click on the ImageStorage folder, i don't see an image, but if i exit the entire applicxation and then i go back in i am able to see the image. How can i refresh the folder wothout having to exit the application?
