Web Forms :: Set The Current Value Of A FileUpload Control?
May 21, 2010
I 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.
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?
I 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?
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.
i want when i click on button it do some thing like FileUpLoad control i means when click on button it open mycomputer window and we can select file and it upload file to server exactly like fileupload control How i can do it?
i have a file upload control to upload picture.i want the user can only upload picture not any other file .when i used file upload control ,user can insert word file also,this should not be done.user can only insert pictures,otherwise message should be appear,like--"please upload valid format"
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?
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?
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...
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..
