View 9 RepliesI have an ASP.NET web application that requires users to select their appropriate time zone so that it can correctly show local times for events.
In creating a simple approach for selecting the time zone, I started by just using the values from TimeZoneInfo.GetSystemTimeZones(), and showing that list.
The only problem with this is that since our application is primarily targeted at the United States, I'd like to show those entries first, basically starting with Eastern Time and working backwards (West) until I reach Atlantic time.
I have a client side JavaScript that generates a date in JavaScript( new Date(2007,5,1)).
I need this date passed through to a hidden field that the code behind can access.
My issue is that when the hidden field is converted into a DotNet datetime, the time is incorrect. This is because the JavaScript is including timezone info from the client browser.
DotNet is then using this info to recalculate the time based on the difference between the server time and the client time.
What i need from the JavaScript is just the year, month and day.
I don't want to pass through 3 int values to my code behind as this will be a major change to the whole app.
What is the best way for me to accomplish this?
If i can set a UTC time with no timezone info I think that might work.
Is there a way to set the max height of a drop down list of a Combo box and use the scroll bars to scroll up and down?
View 1 RepliesI have an Ajax Toolkit Combo Box in DropDown Style (to allow user to enter custom value). The event SelectedIndexChanged and TextChanged works fine if the user select an item of the list of the combo box.
The problem is if the user enter a value that is not in the list of the item of the combo box, the event SelectedIndexChanged nor TextChanged are fired. Is there a way to "force" those events to be fired?
I'm using the Ajax control toolkit Combo box for filtering purpose. If the number of items in the combo box is more and when i try to select an item in the drop down list, the scroll bar in the list automatically flickers in Internet explorer.I read the known issues section in the Asp.Net Ajax control toolkit website, and they say that When ListItemHoverCssClass is specified and the ComboBox list is scrollable, highlighting a list item will cause the scrollbar to flicker when using the Internet Explorer web browser. To avoid this issue, do not specify the ListItemHoverCssClass property.Am not using any ListItemHoverCssClass Property but still it flickers. Please help me on any work around to solve this. I know Auto Complete extender is a best solution instead of combo box, but the clients need combox that should list everything along with editing in the text box.

I am binding same data Table to Combo box and List Box on the WindowsForm Load.
When I select a value in Combo box automatically that value is also getting selected in List Box and same thing when I select a value in List Box that value is also getting selected in Combo Box.
Selection should be only for that particular control, how can I achieve this ?
I am making a page that accepts post data from any number of pages that I cannot change, access, or in any way control.
I need, in one way or another, to get the timezone of the user. I know, ideally the posting page would do this, but I cannot access these pages.
First, there is javascript. I can get the javascript function to return (or change a label to) the correct value, but the problem is I need this info before the postback. I've been trying to write the timezone name on another page and read that page, but I have no idea how to begin to do that? Any other workaround to use the javascript is welcome, or any way to force call this before Page_Load is called?
[code]...
Basically, this works in debug mode, but when it's live only an empty string is returned. I am baffled? Is there any better way to read data from a page? I am using Request.ServerVariables["REMOTE_ADDR"] to get the ip, and that seems to be correct, since it inserts the correct ip into the database I'm using.
Here is the call:
GetTimezone(Request.ServerVariables["REMOTE_ADDR"]);

I will need the timezone database and be able to use it to calculate/convert from one UTC timezone to another timezone.

it returns -07:00:00 offset

I'm trying to write cookies from my website and I'm trying to figure out what implications timezones has over the HttpCookie.Expire property. Should I be passing DateTime.Now.AddDays(1) or DateTime.UtcNow.AddDays(1) or the users's timezone plus a day?
View 1 RepliesWhen a post is made to the site/database, it's made as Universal Time. A user can set the site's default timezone from a dropdown menu in the admin area, which saves the selected timezone to a database table (table: DefaultTimezone, column: Timezone). Now, how can I adjust the following code to display the datetime according to the correct timezone, that was set in the database? So if the Timezone column has "US Eastern Standard Time" in it, it would display the published datetime in that format.
<%#Eval("Published", "{0:MMM dd, yyyy - h:mm tt}") %>
If my user is in California and they have their computer set to PST, it's 1:00 pm there. If my server is set to EST, the current server time is 4:00 pm.
I need a way to get the timezone difference between the client and the server, either in Javascript or C#. In my example, I would get 3 (or -3, doesn't matter).
Does anyone know how to do this?
EDIT: Possible solution for RedFilter
Doing it all in javascript:
serverDate = new Date('<%= DateTime.Now.ToString() %>');
clientDate = new Date();
diffMin = (serverDate.getTime()-clientDate.getTime())*1000*60; //get difference in minutes

View 4 RepliesSuppose I have a string in U.S datetime format, "2/25/2010" and the server is on U.S East Coast with a timezone offset of "-5". When I convert the string via
Convert.ToDateTime("2/25/2010").ToUniversalTime(), it saved as "2/25/2010 5:00:00 AM" (which is correct as local server time for it is 2/25/2010 12:00:00 AM"
Now, suppose my user is in the U.S central time with a timezone offset of "-6", what I want to do is convert it approriately and when this user from central time do "Convert.ToDateTime("2/25/2010").ToUniversalTime()" type of statement, the datetime saved will be "2/25/2010 6:00:00 AM"

View 1 RepliesI have the following code for use in my asp.net website:
CalendarService service = new CalendarService("mycalendar");
EventQuery query = new EventQuery();
query.Uri = new Uri(group.GroupEventsURL);
query.SingleEvents = true;
query.SortOrder = CalendarSortOrder.ascending;
query.ExtraParameters = "orderby=starttime";
query.NumberToRetrieve = 50;
query.TimeZone = "America/Chicago";
EventFeed feed = service.Query(query);
Which produces the following URL:
[URL]
According to the documentation (emphasis mine), I expect the Times in each EventEntry to be in the Central time zone:
The current timezone. If not specified, times are returned in the calendar time zone.
Times in the resulting feed will be represented in this timezone.
Replace all spaces with underscores (e.g. "ctz=America/Los_Angeles").
But my server is hosted in Arizona, so (for now) all of the dates on the calendar are two hours earlier than they should be. Am I doing something wrong? How do I get the dates in the feed to be in the Central time zone even though the server is in Arizona?
I do not plan on moving my hosting any time soon, but since Arizona does not participate in Daylight Savings Time, I cannot simply add two hours to every date.
I want to know about some FREE web service to which i give the ip address as the input and it will return with the Location info(e.g. Country,State,City etc) ,Language info (e.g. en-US,fr-FR etc), and the TimeZoneOffset (with respect to GMT) for the corresponding ip address. I also want this web service to handle DaylightSaving issue properly for any place in the world.
