I have a AsyncFileUpload control on a greybox popup. There are some processing that happens, and then closes the popup registering javascript as a button click event fires.
If i upload a file with the AsyncFileUpload popup page redirects to itself instead of the parent page. It redirects to the parent page as it supposed to if I dont upload a file using AsyncFileUpload. Another thing I have noticed is if I upload a file using AsyncFileUpload popup gets closed and redirects to self on any button click even without the close script call.

I have written a script to create txt documents on my server and i have a listbox on my aspx page that lists these txt documents 1 by 1. What i want to do is click a button to let the user save the selected file to there own computer... sounds simple but im having a mare.
Heres my code:
Code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
'Server.Transfer(MapPath("/") & ListBox1.SelectedValue)
DownloadFile(ListBox1.SelectedValue, True)
End Sub
Private Sub DownloadFile(ByVal fname As String, ByVal forceDownload As Boolean)
Dim path__1 As String = MapPath(fname)
Dim name As String = Path.GetFileName(path__1)
Dim ext As String = Path.GetExtension(path__1)
Dim type As String = ""
' set known types based on file extension
If ext IsNot Nothing Then
Select Case ext.ToLower()
Case ".htm", ".html"
type = "text/HTML"
Exit Select
Case ".txt"
type = "text/plain"
Exit Select
Case ".doc", ".rtf"
type = "Application/msword"
Exit Select
End Select
End If
If forceDownload Then
Response.AppendHeader("content-disposition", "attachment; filename=" & name)
End If
If type <> "" Then
Response.ContentType = type
End If
Response.WriteFile(path__1)
Response.[End]()
End Sub
Here's the error message i get:
Code:
Access to the path 'C:xml' is denied. Permissions is the obvious but i cannot go around changing the permissions on all my end users PC... there must be an easier way?
I want to upload the file to the folder and then save it using the button click ... need to pass its link to the database how would i do that?
View 8 RepliesI have one AsyncFileUpload control ,one Attach button,one Listbox and Save button.
When Users browse the file and click the attach button, filename must be added to listbox. So in this way the user has the option to add upto multiple filenames to listbox. For this i have written the following code
[Code]....
this is source code
[Code]....
In Attach button click event i added the filename to listbox and saved the Asyncfileupload controls in different session variable.
When user clicks on save button all files has to be saved in application folder and for this i wrote the following code.
[Code]....
But iam unable to save all the files . Suppose i added two AsyncFileupload controls to session variables, only last file i,e. 2nd file can only be saved and couldn't get first file.

I have to save a .doc file on the server when the user clicks a button with no 'Open/ Save / Cancel' dialog box.
my code:
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Charset =
"";
HttpContext.Current.Response.ContentType =
"application/msword";
[Code]....
The problem is that the user first sees a 'Open/ Save / Cancel' dialog box. Instead of dialog box, It should be automatically save on server.
i am new to this, would like to ask how can i check which button user click when downloading file, either open, save or cancel ? I need to update to the Database after the user click the save/open button, if cancel, then do not do anythinghere is example of code:
void Page_Load(object sender, EventArgs e) {
I have a reorderlist hooked up with database. I want myself to reorder the stuff in it. Rather than posting the page back everytime when i reorder the stuff, I should be able to make all the changes in my database on button click.
(Basically I dont want my page to post back everytime when I reorde, all the changes made to the list should be commited at the end when Button is clicked)
My page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.
My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.
one button i use to save form entity.and other is to navigate to next pagwhen i click on save button i use jquery to save form entity in database. and form remains as it is
<script type="text/javascript">
[Code]....
[Code]....
i want to display the Save Dialog to appear when the user click at the LinkButton located in the Header Template of the Repeater
P.S: i have tried so may things as you can see in the code but does not seem to work.
I used this code to uploading image and insert it to database
string path = Server.MapPath(".") + "../Upload";
string[] validext = { ".jpg", ".gif", ".png", ".rar" };
string ext =
System.IO.Path.GetExtension(AsyncFileUpload1.PostedFile.FileName);
if (Array.IndexOf(validext, ext.ToLower()) < 0)
[Code] ....
My problem is that it didn't insert image name in database it save some unknown Characters in database. So when I want bind my image from database it didn't show image .
i want to make something like that
<cc1:AsyncFileUpload runat="server" id="upload"
onuploadedcomplete="Unnamed1_UploadedComplete">
</cc1:AsyncFileUpload>
<img onclick='upload.click()'/>
i tried lots of script but it doesnt work.
I have few controls which r validated for blank on a page having 5 buttons
I want the validation to take place only on save button click & not on any other button
<asp:ValidationSummary ID="ValidationSummary1" HeaderText="You must enter a value in the following fields:"
EnableClientScript="true" ShowMessageBox="true" ShowSummary="false" DisplayMode="BulletList"
runat="server" />
I used updateProgress for Downloading File on button click.
it works but when downloading Completes, progress bar did not disappears.
i have place some .txt files in my web application root directory. now i want to open a popup on button click with save button so that client can save this file on his/her PC. also can we auto set the path??? mean client jst press save button and file automatically stored his "D:\Foldersample.txt".
View 1 RepliesI have fileupload control on button click event it is uploading file to my folder. its working fine.
i want as the user give the file path using file upload control browse button it uploads the file user does not need to click on button.
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.

Is there any way to have the AsyncFileUpload button work with 2 buttons:
- A "Select File" button
&
- An "Upload" button
??
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 RepliesI 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?
