Hi Guys, In this tutorial i will let you know about File Upload Extension Check In ASP.NET With JQuery or you can say how to validate File Upload Control To upload only certain types of files.Here i am validating file upload control with the help of JQuery.In my previous post i check the file upload extension with the help of code written in C#, JQuery is lightweight and and added a check at client side, means no processing at server side.
