This may not be the best answer for what you are working on, but here is one solution available. If you are able to use AJAX calls on your website, and if you want to use a little JQuery below is one way to approach saving a list of values from checked grid view rows, in java script, then uses AJAX to send those IDs to your website to do something with the collection.

<script type="text/javascript">

function btnSend(sender, args){
        var idCollection = new Array();
        $('#<%=gvInquiryDocument.ClientID%>').find("input:checkbox").each(function () {
            if (this.checked) { 
                //Find the ID value in the row by cell index
                idCollection.push(this.parentElement.cells[3].innerHTML )
            }
        }

    myWebServiceInterfaceClass.MyWebsiteServiceProxy.UpdateIdCollection(idCollection, SaveResults , ProxyCallFailed);
}

    function SaveResults(results){
        //If you want to send anything back to the site and do something after updating the ids
        //Or just refresh the page and let the onload event repopulate your grid on postback
    }

    function ProxyCallFailed(){
        //Something bad happened on your ajax call 
    }
