Creating A Countdown Timer For A Project?

Dec 6 10 at 16:09

So I'm creating a countdown timer for a project I'm on and I feel its important to get the most accurate time possible. I figure; what is more accurate... and more importantly the most unalterable than server time?

The project requires days/hours/minutes/seconds so if I could grab the exact time the page was requested from the server I could then just through it in a JavaScript variable and work it out from there.

AJAX :: Countdown Timer Counts Double?

Oct 13, 2010 05:10 PM

i added a countdown timer to show seconds before page gets refreshed. But every tick counts 2 seconds instead of 1 .. so it goes from 30 > 28 > 26 instead of 30 > 29 > 28 ..

On page load I set the label value to 30.

The update panel contains following code for 2 labels and timer:

Web Forms :: Make 20 Min Countdown After User Pressed Button?

Feb 21, 2010 08:32 PM

First of all, I'm sorry if I don't describe my problem so well, English is not my first language. I'm working on a project where after the user has pressed a button, the button goes invisible and a label control should say "In 20 mintes you may press the button again". The problem is that if the user presses the button before the current hour is almost over, then he will be able to press the button again. The way I compare the time is by placing th current time, which the user presses the button in a sqldatabase table row for that user. This is my code for the moment for showing the user how long he has to wait:

DateTime TimeSincePressedbutton = Convert.ToDateTime(user.timeSincePressedButton); //value from database
TimeSpan d = DateTime.Now.Subtract(TimeSincePressedbutton);
int dd = Convert.ToInt32(d.Minutes);
int timeLeft = 20 - dd;
ValPointsTitle.Text = "In " + timeLeft.ToString() + " minutes you may press the button again";

and the code I have for comparing time with the time now, is to see if the user may press the button again (which I know is wrong, just cant figure out how to fix it, the reason I compare hour, day, month, year etc is because if the user doesnt show up online the same day, maybe he comes back after a couple of days, or next month, or next year).

if (timeLeft <= 0 && DateTime.Now.Hour == TimeSincePressedbutton.Hour || DateTime.Now.Hour > TimeSincePressedbutton.Hour || DateTime.Now.Day > TimeSincePressedbutton.Day || DateTime.Now.Month > TimeSincePressedbutton.Month || DateTime.Now.Year > TimeSincePressedbutton.Year)
//button becomes visible and the user may press it again

Forms Data Controls :: Timer Control Timer Event Forces A Gridview Databind Every 10 Seconds?

Nov 25, 2010 09:12 AM

VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

AJAX - Client Timer Synchronous With Server Timer?

Apr 23 10 at 9:17

I'm searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.

I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.

Web Forms :: Turning Off The Timer?

Mar 08, 2010 02:01 PM

I think I know the answer to this, just want to make sure.

Question: there's no way to turn off a timer in ASP.NET on the client side (easily—I've seen the undocumented hacks on the net). Therefore, you have to set up you own logic client side while the timer is running server side, correct?

I went through these examples and understand them:



So, the pseudocode for a trigger done programically—so you do something when somebody clicks a button Button1 would be-- after you set up a ScriptManager, UpdatePanel and suitable ASync PostBack triggers in XAML (as per the above links) so that the Ticks event is triggered in the UpdatePanel:

public partial class MyWebForm : System.Web.UI.Page

bool myTriggeringBoolean; //used to turn off and on code in the Timer's Tick event [code]....
