I have one FileUpload Control on my webform. It should be validated with the following:
1.File should be "*.doc"
2.File should be more than 0 KB.
If it is satisfied with above conditions, the file should be rename with "sampledata.doc" and should be uploaded into remote server
i use these code to set limit size for image that users want to upload
protected void BtnUploadS_Click(object sender, EventArgs e)
{
string path = Server.MapPath(".") + "../image/House";
[Code]....
here i define if (fup1.PostedFile.ContentLength < 102400) this size for image but when i upload image that has more than this 100KB it show error ===File size of 756 KB is exceeding the uploading limit but it upload file i don't want users can upload file morethan 100KB but here show error but upload image why?
Please help to understand this RegEx statement in details. It's supposed to validate filename from ASP.Net FileUpload control to allow only jpeg and gif files. It was designed by somebody else and I do not completely understand it. It works fine in Internet Explorer 7.0 but not in Firefox 3.6.
<asp:RegularExpressionValidator id="FileUpLoadValidator" runat="server"
ErrorMessage="Upload Jpegs and Gifs only."
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.jpg|.JPG|.gif|.GIF)$"
ControlToValidate="LogoFileUpload">
</asp:RegularExpressionValidator>
I have Fileupload control in my page
1-i want delete the text that is beside of fileupload button text: no file choesn
2-i want change text of file upload button( I want change Choose file text)
I do not want to change the default settings for file upload, 4Mb is more than enough for the project I'm working on. After quite a bit of searching I found two approaches that were purported to work but neither one is preventing the "Maximum request length exceeded" error. The first approach[see ref. #1 below] performs validation with a custom validator and in code behind on the page that contains the FileUpload control. It doesn't work. The second approach [see ref #2 below] performs validation in the Application_BeginRequest event in Global.asax. The author stated that validation must be handled by this event. Quoting: "The way to get past is to use your Application_BeginRequest event to handle the problem.. This event takes place for each request to your application BEFORE the data has been completely uploaded. Here you can check for the content length of the request and then redirect to the some error page or the same page with some value in session or query string so that the page can show appropriate message to the user." Here is my code from Golbal.asax based on the above. As noted, this approach doesn't work either.
protected void Application_BeginRequest(object sender, EventArgs e)
{
const int maxFileSize = 4 * 1000000; // Slightly less than 4Mb
if (Request.ContentLength > maxFileSize)
{
Response.Redirect("~/FileUploadError.aspx");
}
}
One comment by a reader of the Global.asax approach was that the value returned by Request.Content.Length would include everything on the page, i.e. viewstate, image and text content, etc. I suppose one work-around would be to set the limit higher in web.config but validate for max. file size in code behind, but that seems kind of silly because I'm manipulating the uploaded files (images) to reduce the size anyway; storage space isn't the issue, performance is. Has anyone managed to solve this poblem?
How to get data (read file) chosen in FileUpload control without FileUpload.SaveAs Method on the server? Is it possible write it at once to some object?
View 2 RepliesI have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
View 1 RepliesI would like to know how to use jQuery's Validate plugin to add rules to validate controls in ASCX custom user control?
View 4 RepliesI've ready everything I can find on the built-in validators but can't figure out how to do the sort of validation I need on theclient-side (I can do it on the server-side). Business rule I want to enforce (review the gridview snippet below) is if user checks the CheckBox_EditLifeCycleRpt control but doesn't enter a value in the TextBox_LifeExpectancy control then the validation should fail.
[Code]....
Like I said I can get this done on the server-side but thought it would be a good opportunity to learn how to use one of the compare validators. Also (FYI) I'm not too good at authoring Javascript but I can copy/modify other people's code fairly well.
Is there any way to use FileUpload control only for selecting a file and retrieving its path, without uploading its content?
View 5 RepliesI am writing a web part, and i need to clear the text box part of a fileupload control. Is ther any way you can do this in C# code?
View 1 RepliesI have a 2 FileUpload controls.
Once the user selects a file in the first control, I want to set the default value for the 2nd control to be the value from the first control.
For example, if it were textbox controls I would just use TextBox1.text = TextBox2.text.
How do I do this for FileUpload controls? I tried a few different properties, such as FileUpload1.FileName = FileUpload2.FileName but I get an error saying that they are Read Only.
I would like to simply have an image button on my page that would show an image that says something like "Upload File".When the user clicks the button I would like for it to automate popping up the "select file dialog" exactly like the "browse" button does on the FileUpload control now. Then if the user selects a file and click "OK" I want to do a post back where I can then initiate the upload. If the user clicks cancel from the dialog I would do nothing.So all I am trying to do her is make it so that the user does not see the text box for the file name and replace the plain old browse button with an image and do a postback if they click ok from the dialog.

View 6 RepliesI have a site that uploads multiple PDF files from a CD from one specific computer and that computer is the server that will store the PDF files. I want to do this without having doezens of fileupload controls as the number of PDF files vary from CD to CD.
My problem is that I want the whole process automated. The site will read the names of the PDF files on the CD to the SQL server, which will match, parse, and delete unneeded information with the actual names in a comma delimited textfile. I have that all completed, but i'm only getting the filenames of the PDF and no the contents of the PDF's themselves (They all show 0KB). I am certain that the problem is that i'm pulling from Directory.GetFiles and it's only saving the filenames instead of the files themselves. Is there any way to set the upload path for the filecontrol?
i need when i select a image in fileupload control then path should store in a textbox. actually in gridview i have a image control ,one fileupload control and a textbox control. so when user trying to edit one image and click Edit button from gridview and chose a image from fileupload control then path should be store in relative textbox control.below is my design.

I'm having a little problem with my file uploading. Does anybody know how to maintain the value in the FileUpload control between server posts?
I have a form which, among other things, uploads a file. I am using an ileUpload control (created dynamically) to let a user browse their PC for a file and then using the SaveAs method to upload the file to the server.When I'm selecting a file and Click on Next button for processing then selected file is lost.
Same is happening with me with HtmlTextArea (dynamically generated) , the problem was that I was not again re-initializing the controls after postback. What I did is re-initialized it in Init method of placeholder (as I have created/placed all dynamic controls in placeholder ).
But this thing is not working for fileupload control. I found solution in one of the forum is that "use hiddenField Control to transfer the selected file from the client to server"but this mechanism will only help to retain the name of file
in a hidden variable and the FileUpload1.PostedFile.SaveAs(filename) will not work bcz of absense of object (fileupload1).
here is code:

I have done almost the same in different test project , it works . I dont know whats wrong?

How to correct this?
I have seen many posts here regarding this, but none with a successful solution.I m using a asp.net fileupload control & not the html one.I have various controls on the page, & on a listbox control, listitem selection, page postbacks.So before it, if i had selected a file for upload & page poastbacks, the the file goes off.Now on postback, I have got the filename in a hidden field, but since the Fileupload control doesnt have any setter methods, not able to get how to set the hidden field value & how to set it...
View 2 RepliesI have a site that needs the ability to upload image files. I copied this code from the Microsoft Website:
<%@ Page Language="C#" %>
<script runat="server">
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
try
{
FileUpload1.SaveAs("C:\Uploads\" +
FileUpload1.FileName);
Label1.Text = "File name: " +
FileUpload1.PostedFile.FileName + "<br>" +
FileUpload1.PostedFile.ContentLength + " kb<br>" +
"Content type: " +
FileUpload1.PostedFile.ContentType;
}
catch (Exception ex)
{
Label1.Text = "ERROR: " + ex.Message.ToString();
}
else
{
Label1.Text = "You have not specified a file.";
}
}
</script>..........................
The requirement is that the whole original file path be saved to the database; for example: L:folder1folder2xyz.doc. However; the FileName property of the FileUpload control will only give "xyz.doc". We are interested in obtaining the full path only and really not interested in using the control to do any upload.
Is there any way to get the full path? We would like our user to be able to browse to the target file instead typing into a textbox because the folder name could be very long and several levels deep in our organization.
I need to create folder and save in to the documentfor example:Suppose if upload the file that file should be save into as/as1/filename like i want saveas/as1/filename, this name will chnage for different different actions..
