Just simply use

var divId = document.getElementById('YourDivID');

You need ClienID for Server Side control. And i believe your div is in your client side .

Where is the above code written? In the external JS file? If yes, it is not gonna work. You need move this to your page, get the client id and pass to your JS method which may be in external file. :)

You cannot use server side code like document.getElementById('<%=Parent.ClientID%>'); in your external .js file. Declare a global variable in your page and store the id of div tag in it. Then refer this variable in the .js file to get the client id. Declare this variable in your page: var yourDivId = '<%=Parent.ClientID%>'; Write this code in the .js file to get the above div id var objDiv = document.getElementById(yourDivId);

Are you the clientID of your div. Try this First assign the clientid in javascript variable like var hdnCtlSelectedItem = "<%=Parent.ClientID%>"; then check whether the you are getting the clientid.and pass this ID to javascript function i external JS file Afterthat access the divid using document.getElementById(hdnCtlSelectedItem);
