Web Forms :: FileUpload Control - How To Maintain Client Directory Path On Postback
May 4, 2010
I'm using five FileUpload controls on a single web form. Besides allowing the user to upload a file I also am collecting user data. Problem I run into is during the server side validation if any of the user data is invalid on a post back when content it redisplayed the FileUpload controls loose the client url that was selected when browsing. How can I keep that path or set the pathing on the control so they do not have to keep rebrowsing for the files on data validation errors? Right now breaking up the two form sets user data and file upload into two pages is being frowned upon and requirments would like it to be on all one page.

I have a FileUpload control and a DropDownlist control in an UpdatePanel and when user select a file for the FileUpload control (no upload yet), in the meanwhile the user select an option from the DropDownList control which will cause a postback! Once the page postback, the path selected in the FileUpload control will gone. How can i remain the path in the FileUpload control? File uploading function was working. I hope can remain the path in the FileUpload control during postback.
I have tried the solution below but the "FileUpload1.HasFile" will return false to me.
If Session("FileUpload1") Is Nothing AndAlso Upload.HasFile Then
Session("FileUpload1") = Upload
lblPhotoUploadErr.Text = Upload.FileName
ElseIf Session("FileUpload1") IsNot Nothing AndAlso (Not Upload.HasFile) Then

i am using Fileupload and 3 dropdown control in update panel, 3 dropdown will be post back on dropdown selected index change event (i.e like Country,states and city... get the value from db as per country,states and city)
THE PROBLEM IS
While postback the filename path is gone from the file upload control(as expected/ or Default property).
I am converting the file to byte array, to store in the database from file upload control.
How can i retain the value or Is there any way to solve this issue.
Is there any ajax control for file upload or any free controls which retain the value after postback also...?
Or it is possible to set the value to file upload control during postback ?

I 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?

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 am using a fileupload control to display the contents of a text file in a textbox..if i use this
<asp:FileUpload ID="txtBoxInput" runat="server" Text="Browse" />
string FilePath = txtBoxInput.PostedFile.FileName;
it will get only the file name like bala.txt.i need like this D:New Folderala.txt
Instead of fileupload control i have used textbox to get the path like this D:New Folderala.txt
<asp:TextBox ID="txtBoxInput" runat="server" Width="451px"></asp:TextBox>
string FilePath = txtBoxInput.Text;
But i need browse button instead of textbox to get the path..
EDIT:My button click event
protected void buttonDisplay_Click(object sender, EventArgs e)
{
string FilePath = txtBoxInput.PostedFile.FileName;
if (File.Exists(FilePath))
{
StreamReader testTxt = new StreamReader(FilePath);
string allRead = testTxt.ReadToEnd();
testTxt.Close();
}
}

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?

I have a situation where I want a user to select a file, then select an option from a DropDownList. When they select an item from the DropDownList I do an auto post back and do some stuff with the file, but this causes the path to clear out. Is there some way that I can keep the path from clearing out?

I have an asp.net c# web forms application that uses a file upload control to load documents to a specific folder. The location to upload the file is ~Assignmentsassignment_docs.
The error code is:Could not find a part of the path 'E:webmeAssignmentsassignment_docsfilename.xlsx'.The following is the code behind:
protected void btn_fuc_assnmt_doc_Click(object sender, EventArgs e)
{
int i = 0;
string filename = fuc_assnmt_doc.FileName;
if (fuc_assnmt_doc.HasFile)
{
while (System.IO.File.Exists(Server.MapPath("~/Assignments/assignment_docs/") + filename))

This works just as expected in dev on my localhost, but I get the error when I try it on my Winhost server.Is there an issue with the code or possibly with my IIS settings?
