Its because when you are using User Control or anything ASP genrate a unique client id to every control you are giving wrong i Id i guess unction InputChange() { var ctl=document.getElementById("<%=txtEmp.ClientID %>").value; alert(ctl); }

Most likely the id of the control on the emitted page is actually something like: ctl00_master_txtEmp or similar. Look at the source to find this: it is named after the parent element (such as the ContentPlaceHolderID). As an example right click this page, click view source and you will see many examples of this. Your code would then be: var ctl=document.getElementById('ctl00_master_txtEmp').value; alert(ctl);

Its better to give a client id dynamic instead of static Check my above modified code that will work
