Upload file to server

priyagee

Hai all, I need to upload file to server and i am using input file to upload the file, my problem is postedfile.filename is always null. I have tried using updatepanel and had same problem. Can anyone help me.

File upload doesn't work under UpdatePanel ByDefault. you need to set PostBackTrigger in <Triggers> Section of UpdatePanel by which you can force a complete PostBack.

Make sure you are using it under !Page.IsPostBack Condition.

Actually in my form i had a ultrawebgrid and a template column as button, when click the button by client side the value ll be assign to the fileupload control and when i click the upload button the file should be uploaded . My ultrawebgrid and upload button is inside refresh panel and fileupload is outside the refreshpanel.

You can't assign the filename in an upload control with javascript. That is a security feature. Otherwise a web site could tell the browser to upload things like password files and steal data.

Hi! I recomend you to use Uploadify control of jQuery! Is the easy and best upload control! for multiple or single, max capacity, type of files, queue files in progress, multi browser, etc! Here[^] :)

He's probably not asking of assigning values rather He wants value inside.

Yes i need only the value , in client side i am getting the path value but in server side it is null.

string fn = Path.GetFileName(inputFile.PostedFile.FileName);
string savepath = Server.MapPath("Exports") + "\\" + fn;//Exports is a folder where u will save all the posted files...
inputFile.PostedFile.SaveAs(savepath);//makes a copy of the file onto your server...
string[] lines = File.ReadAllLines(savepath);//will read all lines from a file

for (int i = 0; i < lines.Length; i++)//loop through all the lines in your file
{
//do everything you want with the file contents
}

; Hope that helps.. Later!

You might want to take a look at what exactly you are doing in your Page_Load event...you could be reseting the values of your controls... Put the code above in a method e.g.:

protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
UploadFile();//call your method here...
}//or put this ispostback check in the click event of the control/button that will do the uploading process
}

protected void UploadFile()
{
//put the code i gave you here...
}
