how to set file name at the time of file is downloading in vb dot net
View 1 RepliesI'm saving a file with the asyncfileupload ajax plugin from the ajax toolkit and when I save it I'm changing the filename (to avoid multiple files with the same name).
After the file is uploaded, the user needs to know what the file has been named so I'm using this javascript code on the onclientuploadcomplete event.
function UploadComplete(sender, args) {
alert(args.get_fileName());
}
This works except it gets the old name, not the new name (which is determined server-side). Is there any way to get it to return the new name rather than the old name? Or any work around to achieve this?
This is my code in the code behind the get the new filename:
string filename = DateTime.Now.ToString("dMyHmsf") + e.filename;
string strPath = MapPath("~/SavedImages/") + filename;
AsyncFileUpload1.SaveAs(strPath);
I have web application using asp.net and from that i generate crystal report after generation of report when i'll export it to pdf from crystalreportviewer inbuild function. So report is saved by name crystalreportviewer.pdf but I want to change name of report at the time of generation.
View 1 RepliesI want to update an updatepanel after the user has uploaded a photo via the asynfileupload control.

I'm using ajax.toolkit asyncFileUpload to do the async image upload.
I don't know how to get the new file name that i give it in server side.
This js function
[Code]....
only returns the name of the filename on the client, not the new name that I have given server side
how can I do?
I have my asyncfileupload set up to give the posted file a new guid as its filename, what i need is the NEW filename so i can insert it into a database. PostedFile just gives me the original name, as does args.get_fileName().
Here is my codebehind:

I have the asyncFileUpload control inside a user control which is a wizard control step. The wizard control is inside a AJAX update panel.
I have a requirement to save the complete folder path along with the file name when user selects a file in the asyncFileUpload control. In order to achieve this on the server side UploadedComplete even I save the PostedFile.FileName to a session variable.
Then on the client side OnClientUploadComplete I force a postback for the UpdatePanel. In the postback I get session variable value and then do my processing.
server side upload completed event when I save the posted file name to a session variable. This is working in my local machine. I am able to retrieve the Session variable on the postback, but when I move the code to my test server the Session value is coming out as blank. I validated that the UploadedComplete event is triggered on the server, but for some reason the Session value is blank.way I can get the PostedFile name (complete path) on the Client side?
How would I go about having a thumbnail preview of an image that has been uploaded through AsyncFileUpload?
View 2 Replies I have a question. How do you rename a file from an upload control and save it in webserver folder?. Actually I know how to save it in the webfolder. All I want to know is how to check if the file already exist and to rename it if it exist with an addition of number to the file uploaded? Here is my code now. But I wanna add another number to it with the orignal file name.
filepath = Server.MapPath(
"~/Resumes/" & UploadResume.FileName)
I want to add the date/time and the user's ID to a file name before I uploaded the file into the web server. How do I do that?

How I can change the html tags of uploaded file?
Is it actually possible to change the button text on the AsyncFileUpload control from "Browse" or "Select File" to something else without having to modify the control's source code? it seems I have to apply all sorts of hacks and workarounds for such a simple requirement. I fail to understand the authors of this brilliant control haven't thought about this (or is it too complicated for them to do it). and also Is it possible to have two buttons one for selecting the file and one for uploading?. because it is confusing if the user thinks if he is simply selecting the file where as it does the upload as well. at least if I can change the caption to "browse and upload" that makes it clear. I think these two functions are merged now without giving any ability for the user to separate them if he wishes to do so. if there is a simple workaround at least if there is no straight forward way to achieve this.
View 1 RepliesHow to know the FileName AjaxFileUpload in the event Click of a Button without going through earnest for this is what I found that is to say that the FileName is only in the event Designed AjaxFileUpload1_UploadComplete.
protected void InsertButton_Click(object sender, EventArgs e) {
lblMSG.Text = ViewState["filename"].ToString();
}
protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) {
ViewState["filename"] = e.FileName;
}
protected void AjaxFileUpload1_UploadComplete (object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) {
string filePath = "~ / upload /" + e.FileName;
AjaxFileUpload1.SaveAs (filePath);
}
I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.
I am using this control to give the user the possibility to upload up to 5 pics. Well, it generally works fine but i started to test it using a folder full of pics. This folder contains more than 900 pics which are named from "DSC_8138.jpg" to "DSC_9255.jpg" (some has been deleted).
When i try to upload the pic "DSC_8138.jpg" it saves the pic "DSC_8168.jpg".
When i try to upload the pic "DSC_8141.jpg" it saves the pic "DSC_8147.jpg".
There is not any clear critieria in this.
I am quite sure that my code in the AsyncFileUpload1_UploadedComplete method cannot cause this problem. Actually, when i try to upload the pic "DSC_8141.jpg" the file name is still "DSC_8141.jpg" even though the pic uploaded is the "DSC_8147.jpg". in any case, the control deals with the uploading process.

I am just about to learn how the AsyncFileUpload component works. I have come up with some code but this does not compile excactly. It seems but are not sure that I need to declare some events etc... I will explain excactly what my goal is to do. It will be possible to upload a .jpg file from a users computer and save this file to the below path with a new name:
UploadedFile.jpg
"~/Folder1/Images/"
[Code]....
Is there any solution short of posting back, which completely defeats the entire purpose of this control?

I'm developing a website using .NET 3.5 and I'm having problems with the asyncfileupload control.The problem occurs when you upload a file, and then try upload the same file again. On the second upload, none of the clientside nor serverside methods fire. Everything works fine if you upload one file, upload a file with a different name and then upload the first one again.
This is a bit if a pain because on the page i allow the user to delete the uploaded images so i need the functionality to upload a file with the same name as the previous upload.Has anyone else encountered this and are there any work arounds?

I have downloaded a AsyncFileUpload example, I edited the uploadError javascript and now it is working perfectly:
[Code]....
It works perfectly how I wanted it, like this: I upload a file, if it's an Image I get the Lime AsyncFileUpload background, and the file name and size are written under the AsyncFileUpload, if it's not an Image, I get the error label shown, with red AsyncFileUpload background, and if I upload another file, it keeps working the same thing every single time, but only shows the last uploaded image name at the end of an image upload, not all of the images.I tried to merge it with my website, and ended with this code:
[Code]....
but in my website its just working the first time only, then rest times I'm getting the uploadError() function working instantly when I click upload, even if i have selected an image or anything else.
How would I NOT overwrite a file if it exists on the server already using the AsyncFileUpload control?
View 2 RepliesI am using an AsyncFileUpload control inside a FormView. I only want the file to saved during the FormView's ItemInserting event. In trying to find a way to do this, the only thing I could come up with was to store the AsyncFileUpload control or the PostedFile in a Session variable during the OnUploadedComplete() event and then invoke the SaveAs method in the ItemInserting event. Problem is the SaveAs method is throwing an exception saying "Cannot Access A Closed File". If I invoke SaveAs in the OnUploadedComplete() event, it saves successfully, but I need it to only save when the user submits the form. this error or perhaps a better way to save the file during ItemInserting()?

I've noticed that Page_Load event fires when file is asynchronously uploaded. How can I check if postback was caused by AsyncFileUpload?
And why FileContent .Position is always at the end of stream? (it started to be so after the deployment, was ok while developing!)
