i want validate file upload from client side can u suggest code in java script

AFAIK in javascript we cannot perform this action..
what you can do is, create a small popup window for uploading, in that you can check the dimensions and validate it..
so that post back will not be there for the parent page...

its not suitable for my page because my page contains 4 file upload controls.

you can create a single pop for all 4
