如何从asp：FileUpload获取文件名并使用ASP.NET和C＃显示在标签中

Question

I am using a <asp:FileUpload> to upload a PDF file to my web page. But after clicking on browse the window opens, and once I select a file and click on Open i want to get the file name and display it in a Label . What function should I use in ASP.NET to do this? I tried the OnLoad , OnUnload , OnDataBinding , etc. in the <asp:FileUpload> but nothing works. Can someone suggest me a solution for this?

My code is as below:

<asp:FileUpload ID="fileUpload" runat="server" /><br />
<asp:Label ID="labelFilename" runat="server" Text=""></asp:Label>

Once I select a file and click open the file name should be displayed in the label.

You can use this code:

<script>
    $(document).ready(function () {
        $('#fileUpload').change(function () {
            var path = $(this).val();
            if (path != '' && path != null) {
                var q = path.substring(path.lastIndexOf('\\') + 1);
                $('#labelFilename').html(q);
            }
        });
    });
</script>

You can access the file name(server side) by using following code snippet

string file_name=fileUpload.FileName.ToString();

You can access the filename on client side using following code snippet

$(document).ready(function () {  

            $("#fileUpload").change(function () {  

                var FileUpload = $("#fileUpload").val();  
   ... }
 }
