You can use the below regular expression to validate the file extension.
^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))+(.csv|.CSV)$
Complete Code:
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script> function validate() { var uploadcontrol = document.getElementById('<%=FileUpload1.ClientID%>').value; //Regular Expression for fileupload control. var reg = /^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))+(.csv|.CSV)$/; if (uploadcontrol.length > 0) { //Checks with the control value. if (reg.test(uploadcontrol)) { return true; } else { //If the condition not satisfied shows error message. alert("Only .csv files are allowed!"); return false; } } } </script> </head> <body> <form id="form1" runat="server"> <div> <asp:FileUpload ID="FileUpload1" runat="server" /> <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return validate();" /> </div> </form> </body> </html>
