            }
        });
    });
</script>
<div id="ReplyDetails">
</div>

& i want to send Id only By this Ajax

What you need to do is simply write out the value from the viewdata in the appropriate place. Something like this:

....
url:'/Marker/MarkerDetailPartial/<%=ViewData["id"]%>',
....

Or like this:

....
data:{'id':<%=ViewData["id"]%>},
....

Remember that all server side code is already executed and rendered when your javascript executes.
