Web Forms :: Display Countdown Timer Of Remaining Time
Feb 15, 2010
I am a newbie and have designed a website using ASP .Net 2.0 with C# 2005. On the home page I am displaying rates of a few items which gets updated every 15 minutes. The new rates are entered through a different web page into a SQL Table and I am using Page Refresh of the home page to update the rates every 15 minutes. Everything is working ok upto this. But now I have to display a countdown timer of time remaining for the next update on the home page. I am totally clueless as how to approach the problem.
I want to add a countdown timer to my page. What happens is when the user presses the 'Process' button it goes out and performs various tasks and displays results to a listbox. I want to add a 10 - 1 countdown timer so the user knows its actually moving. Once it gets to 1, I need it to start over from 10 until it is finished.
How do you make a Countdown timer? When the user loads the page, clock starts counting down, it reaches time, it redirects browser to a new page.Found this, it was not too useful.
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.
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:
[Code]....
Code behind:
[Code]....
There is another timer on the page that forces a refresch every 30 seconds:
I am Creating Timed online test in C# asp.net.I have created it using the local machine time. But in the case of Database disconnection or system hang, The countdown timer must start from the time at which the machine has hanged or unexpected database disconnectivity.For example the user is answering the Questions for 10mins and unexpectedly system hanged. After recovery the countdown must start from 10mins. Can anyone please help me with coding in C#? I have used the following coding, But its not useful in the above scenario.
I am querying the SQL database table and returning the result on the webform with a repeater, but I need to display one record at a time and refresh with an update panel and timer to iterate through the rows of the table one at a time at a fixed interval.
Is there another solution to be able to display one record at a time using c# in the webform, but then cycke through the other records one at a time using a timer control and updatepanel?
I have an event in 20 days - on my site I want to put a label withthe text - " there are now (daysleft) to the big day"Every day I want the int in the (daysleft) to count down like 20, 19, 18, 17 etc.is there a simple way to do this using a loop or something??
I would like to pop up a box that warns the user of session timing out in 5 minutes. There are lots of examples of this on the net and I can figure something out. My question however is how to get the time remaining.All examples I read about set a client side timer to countdown from last postback. I would like to do something different. I would like to make an AJAX call to the server and get the time remaining from the server. Is this possible?Since an AJAX call will not reset the session timeout timer can I read the number and send it back to the client?
I have a datalist inside 1 datalist.In the first datalist i am binding the "advertisement posted" date field from sql server. In the second datalist i am binding the ads posted on that date using an object datasource. my pro is, i need to show a total of 100 ads in one page. This should not depend on the date. Total 100 postings in the page. For example
Todays date (02/25/2010) 50 postings yesterdays date (02/24/2010)
if 75 postings are there,
50 postings
it should display only 50 postings under yesterday's date remaining 25 postings should display in next page(paging) with the format like this
yesterdays date (02/24/2010) remaining 25 postings (02/23/2010) 75 postings
I want to show countdown time in the status bar of browser like: You session will timeout in 40:00 minutes. You session will timeout in 39:99 minutes. I mean it should countdown to 0 and popup a window if user click Popup's Ok button then it should show a redirected page. No ajax support required. I want manually coding therefore I am not allowed to write anything in web.config also.
I have a quiz application in which i am adding from date and to date. If the todate expires then that quiz will not come from the database. Now i want the timer also with the todate.
For example - fromdate is 1/6/2011 and todate is 6/6/2011. I am using DateTime object for these fromdate and todate. In between these dates i have 4 quizes. I want to set times for these four quizes so that they will expire when the timer time is over.
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.
I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.
I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.
However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.
Find if the current time falls within hourly ranges and display the start hour and end hour of that range in labels.
Examples:
If the current time is 8:46am, label startTime would return "8am" and label endTime would return "9am" If the current time is 10:01pm, label startTime returns "10pm" and label endTime returns "11pm" If the current time is 12:59am, label startTime returns "12am" and label endTime returns "1am"
I have been working with the C# TimeRange class but not getting what I need.
