[Solved] Save value to session

[Jonisan]

I need the value from a DatePicker and a DropDownList to be saved to session . 
For this I added to them a  ".ClientEvents(events => events.OnChange("onChangeDatePicker")"
and so I have the changed value of the datePicker and Dropdown in those javascript functions .
I don't think this is the way to do it , because I was unable to save those values to session from that point.

If this is the solution plzz help me with what I miss , but I dont think it is .. I think the solution is to
map a session variable to DatePicker and DropDownList current value , but I don't know how. 


Thank you

I got a solution to send to server the value to be added in the session : 
function onChangeDatePicker(e) {
        $.post('<%= Url.Action("DateChanged","Home") %>',
            { dateTime: e.value.toString() },
            function (result) {
                // .
            });        
    }
If there is a better way to do it plzz sam1 say that ..
