Asp – Retain value in fileupload control

asp.netfile upload

I am writing a file upload application. So it contains a keyname in textbox and a fileupload
control. A save button is used to save the keyname and the file. My issue is when I select a file in fileupload control and I donot enter any value in keyname textbox and click on save button, a message is shown 'enter a keyname' but the fileupload control is cleared. How can retain the value in the fileupload control?

You can't retain value in FileUpload control. This is because of security reasons. you can use RequiredFieldValidator for keyname textbox.

C# – Getting the path of a file using fileupload control

You can get the file name and path from FileUpload control only when you are in debug mode but when you deployed your app. in server then you cant because that is your client address which you are trying to access by server side code.

protected void Button1_Click(object sender, EventArgs e)
{
    string filePath,fileName;
    if (FileUpload1.PostedFile != null)
    {
        filePath = FileUpload1.PostedFile.FileName; // file name with path.
        fileName = FileUpload1.FileName;// Only file name.
    }
}

If you really want to change properties or rename client file then you can save file on server on temp folder then you can do all thing which you want.

Display only file name in FileUpload control

I'm pretty sure that isn't possible. You cannot set the value inside of the FileUpload control's textbox at anytime, via server side or client side script.
