[Solved] RadScheduler DateTime string format

[Sentia]

Hi im using the client side edit for the scheduler top redirect to another page. This gives me a url like:

activity.aspx?start=1175232600000&allday=false

Just wondering how I can interpret the start datetime?  Do I need to new up a RadScheduler?

Thanks!

Hi Sentia,

I guess that you are referring to the RadWindow integration example. The date here is represented as JavaScript ticks. You can use the following code to convert them to a date on the server:

private DateTime ParseJavaScriptTime(string jsTime)
{
    Int64 tickDiff = new DateTime(1970, 1, 1).Ticks;
    Int64 jsMilliseconds = Int64.Parse(jsTime);

    DateTime time = new DateTime((jsMilliseconds * TimeSpan.TicksPerMillisecond) + tickDiff, DateTimeKind.Utc);
    return time;
}

This is not the best solution and since the initial version, we have improved the example to use a more readable date format. The new version is not uploaded yet, but you can use the following JavaScript code to format the date for use in the query string:

function formatDate(date)
{
    var year = padNumber(date.getUTCFullYear(), 4);
    var month = padNumber(date.getUTCMonth() + 1, 2);
    var day = padNumber(date.getUTCDate(), 2);
    var hour = padNumber(date.getUTCHours(), 2);
    var minute = padNumber(date.getUTCMinutes(), 2);

    return year + month + day + hour + minute;
}

function padNumber(number, totalDigits)
{
    number = number.toString();
    var padding = '';
    if (totalDigits > number.length)
    {
        for (i = 0; i < (totalDigits - number.length); i++)
        {
            padding += '0';
        }
    }

    return padding + number.toString();
}

Then on the server-side you can parse it like this

private DateTime ParseJavaScriptTime(string jsTime)
{
    DateTime result = DateTime.ParseExact(jsTime, "yyyyMMddHHmm", null, DateTimeStyles.AssumeUniversal);
    return result.ToUniversalTime();
}

The example will update soon on the site and will be included in the upcoming Service Pack.
