FileUpload control issue

[kenexcelon]

I am running into an issue with the fileupload control. Standard code... just a test After clicking on button1 I do get the Yay response. Clicking button1 again right after, I get the Nay response. However, if I choose a file and then click on button1 and it has a file, I get the Yay response and the text in the upload control clears. I refresh the page, and I get the Yay response. Is there a way to control this?

    protected void Button1\_Click(object sender, EventArgs e)
    {
        if (this.FileUpload1.HasFile)
        {
            Response.Write("Yay!");

        }
        else
            Response.Write("Nay!");
    }

That is how the file up load works. The file upload control will post the file only once. Think about it. If you have a file selected by the user, would you want that file to be sent to the server on every additional postback? protected void Button1_Click(object sender, EventArgs e) { if (this.FileUpload1.HasFile) { Response.Write("Yay!"); //Implement method to save file } else Response.Write("Nay!"); }

I didn't get any requirements for the signature

I understand that's how it should work. And no, I don't want the file to be sent on every postback. Just if you click an upload button with a file in the upload control, and a user clicks refresh on their browser, the same action is performed and the upload control still is showing HasFile = true. I'm trying to not let the code to add a file run again if a browser refresh is performed after clicking upload.
