Get file size before upload using jqueryPrint
File uploading functionality is generally used by the developers. Before uploading file on the server, to know the size of file is a good practice. By knowing file size, we can restrict the end user to upload large size files on the server since we have limited space on the server. We should check uploaded file size on server side as well client side. In this article I am going to expose how you can get size of file before uploading on client side using JQuery. For more help refer the article Asp.Net asynchronous file upload using jquery.

Using above defined function "GetFileSize", we can also get file size in Asp.net also like as :
<form id="form1" runat="server"> <asp:FileUpload ID="fUpload" runat="server" /> <asp:Button ID="btnGetSize" runat="server" Text="Button" OnClientClick="GetFileSize('fUpload');" /> </form>
Above example will work on all browsers including IE, FF, Chrome, Safari, Opera etc.
