What do you actually want to do? Your question makes no sense.

Hi

I am guessing you mean to set the file uploaded path as one linkbutton, so that when you click the linkbutton, you can easily find

the upload file.

Do you think so?

Hi,

If you mean the path value, you can first save it in a hidden field and then access it in the client side.

HiddenFieldID.Value = "Path where you are saving the file"+FUAttachContract.FileName;

In javascripts, you can access that value using the below code.

document.getElementById('<%=HiddenFieldID.ClientID%>').value

Hi, you can save the upload file path to a hidden filed, and then get it with LinkButton click event. With the following example, after choosing the upload file and clicking “Upload” button, the file will be uploaded to server and the file path will be saved to the hidden field. Then please click the LinkButton, it will get the file path from the hidden field, find the file and show its content to Label “lblResult”.

Markup:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:FileUpload ID="FUAttachContract" runat="server" />
        <asp:Button ID="ButtUploadCntract" runat="server" Height="22px" Text="Upload"
            Width="67px" onclick="ButtUploadCntract_Click" />
        <asp:HiddenField ID="HiddenField1" runat="server" />
        <asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">ShowContent</asp:LinkButton>
        <br />
        <asp:Label ID="lblResult" runat="server" Text="Label"></asp:Label>
    </div>
    </form>
</body>
</html>

C# codes:

protected void Page_Load(object sender, EventArgs e)
        {
            
        }

        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            string content = showTxtContent(this.HiddenField1.Value);
            this.lblResult.Text = content;
        }

        private string showTxtContent(string path)
        {
            string instream = "";
            string getstream = "";

            if (File.Exists(path))
            {
                StreamReader sr = new StreamReader(path, Encoding.GetEncoding("utf-8"));
                instream = sr.ReadLine();
                while (instream != null)
                {
                    getstream += instream;
                    instream = sr.ReadLine();
                }
                return getstream;
            }

            else
            {
                return "file doesn't exist";
            }

        }

        protected void ButtUploadCntract_Click(object sender, EventArgs e)
        {
            string path = AppDomain.CurrentDomain.BaseDirectory + "\\" + this.FUAttachContract.FileName;
            this.FUAttachContract.SaveAs(path);
            this.HiddenField1.Value = path;
        }
