I have two ways to bind gridview one is server side one is client side spservices so which one is better faster and efficient

Question

Server side

SPWeb site = SPContext.Current.Web;
                SPList list = site.Lists["GridList"];
                SPListItemCollection items = list.Items;
                DataTable dt = items.GetDataTable();
                Gridnames.DataSource = dt;
                Gridnames.DataBind();

client side

function getToolInfo() {

       // var CamlQuery = "<Query><Where><Eq><FieldRef Name='Title'/><Value Type='Counter'>" + lastID + "</Value></Eq></Where></Query>";
        var CamlViewFields = "<ViewFields><FieldRef Name='Title' /><FieldRef Name='Description' /></ViewFields>";

        // this let me know that the function is getting called and passed the correct parameter value
        alert('function called and passed last ID of : ' );
        $().SPServices({
            operation: "GetListItems",
            async: false,
            listName: "GridList",
            CAMLViewFields: CamlViewFields,
            // CAMLQuery: CamlQuery,
            completefunc: function (xData, Status) {
                $(xData.responseXML).find("[nodeName='z:row']").each(function () {
                    alert($(this).attr("ows_Title"));
                    alert($(this).attr("ows_Description"));
                });
            }
        });
    }

Answer 1

It's really not a question of which method is "faster", but what your requirements are. There are times where one or the other method is preferable, but it really depends on the context.

Answer 2

I will suggest to go with server side call if there is an option and to have a better performance from the server. These calls are handled by the core libraries and client object model calls are handled by a different libraries which takes the calls in batches.

If the question is specific to performance and if there is scope for server side implementation then I strongly suggest to go with server side calling.

At times we require asynchronous calling to server and in these scenarios client object model is preferable.

Hope this helps you!!!
