How to Pass a variable from NumericUpDown control to web service

[kenshinofkin]

I am trying to create a textbox that when the user clicks on the up or down arrow a minute will be added or subtracted to/from the time. I created a web service thinking I could pass the current time to methods that add and subtract one minute from the current time. But I am unsure of how to pass a DateTime variable or if I even can.

Here is my webservice:

[System.Web.Script.Services.ScriptService()]
    public class NumericUpDownService : System.Web.Services.WebService
    {
        [WebMethod]
        public DateTime NextTime(DateTime currentTime)
        {
            currentTime = currentTime.AddMinutes(1);
            return currentTime;
        }

        [WebMethod]
        public DateTime PerviousTime(DateTime currentTime)
        {
            currentTime = currentTime.AddMinutes(-1);
            return currentTime;
        }
    }

and my control:

<cc1:NumericUpDownExtender ID="TimeNumericUpDownExtender" runat="server"

TargetControlID="TimeTextBox" 
Width="70"

RefValues=""

ServiceUpPath="NumericUpDownService.asmx"

ServiceDownPath="NumericUpDownService.asmx"

ServiceUpMethod="NextTime"

ServiceDownMethod="PerviousTime" >

</cc1:NumericUpDownExtender>

How do I pass and get back a datetime object to/from my methods NextTime and PeriousTime? Thanks for any help!

Perhaps using a SOAP Header would work for you.
