How To Use A Timer / Update Panel And Repeater To Display One Record At A Time Using C#
Jul 1, 2010
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 a bit of a strange problem and wondering if anyone can help.I have an update panel that has a timer set as the AsyncPostBackTrigger. In the repeater I have a few buttons which have on click events.The on click of these buttons does not appear to fire until the timer has ticked. My code is as follows:
i am attempting to use javascript to update the chart, because how i have setup now causes the chart to just disappear. Here is the code i have now: I am calling the chart to page using: on default.aspx
[Code]....
Code on the dataURL_Infrasturcture_Capacity.aspx page:
[Code]....
PROBLEM: So how would i update this using an update panel and timer. Currently when i do it the chart just disappears on update. I believethis is due to the fact that i am calling a dataURL. How would i get this to work javascript?
I am doing a countdown with a timer that runs every second. I have a scriptmanager, but how do I make it update behind the scenes so the user does not see it? I thought I could use an update panel, but I can't get it to work right.
I've a tab container with 4-5 tabs on a page. On the same page, I've three update panels - one outside tab container whilst the other two lie inside two tab panels separately. Update mode of all three update panels are set to Conditional. There is a timer in the first update panel (the one outside tab container). Whenever timer ticks, the other two update panels are also being refreshed. How can I stop this?
ASP.net VB timer control: in the code behind, when I change a value of a textbox on other control. It does not change if not in panel. Anyway to change a value if not in teh panel.
Sub UpdateTimer_Tick(ByVal sender As Object, ByVal e As EventArgs)Dim x As Integer DateStampLabel.Text = DateTime.Now.ToString() (L_ticks.Text= CInt(L_ticks.Text) + 1 If (cint(L_ticks.Text) = 10 Then L_start.Text = DateTime.Now.ToString() ' reset value not in panel l_diff.Text = DateDiff(DateInterval.Second, CDate(L_start.Text), CDate(DateStampLabel.Text)) End Sub
I have an Ajax timer that has an interval of 1 second and an update panel on my page. If I leave the page open and never close or refresh I notice that after 6 to 8 hours the timer stops firing. No error messages.......everything just stops. If I refresh the page everything starts working again. Are there any issues I am not aware of when running a page for a long time using the Ajax timer?
I have an ASPX page with several update panels. They all have their UpdateMode="Conditional".
Some panels are refreshed when the user clicks a button and other are refreshed regularly, with a timer.
The panel refreshed with a timer launches a database query and many validations on the data. Then display the result in a panel when errors have been found.
That all works fine except when the validation has to delete files on the disk. (.txt, .jpg, etc it depends). In that case, after the validation is made, I am always kicked out of my website because of the error (Thread was being aborted). So I loose all my session variables which means I am not logged off.
Anybody had that kind of problem ? Is it normal that deleting files AND directories on the server make me loose my session? Is there a way to prevent that ?
I'm having a problem where users with a slow connection aren't getting my image feed properly.i'm sending them new images every second to a picturebox inside an Ajax Update panel, using an Ajax Timer.so if their connection is really slow, one image doesnt load fully before the next one comes in, so they never get the whole picture...And for people with a faster connection, I would like to increase the update rate, and currently I see no way of dynamically setting the update rate.
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 have a panel bar..each time I press panel bar item I display ascx control with in update panel..but it lakes update panel loading time lot..how I can decrease that loading time?
I have a requirement like need multiple update panel in web page and also i want to load only one (targeted one)Â update panel content when I click button on another update panel.
I have an update panel on my page. Within that is a repeater which has a user control in it. Inside the user control I allow an update to the datasource of the repeater. I am able to successfully save the data to the database but when I call the .Update method of the update panel, the user control is blank. If I proceed to refresh the page, the data appears with the changes I made. why the data is disappearing when I call the .Update method?
I've two SqlDataSources and two Repeaters, each repeater contains one hyperlink (i also tried using web server button and anchors). The hyperlinks fetch from the database some values and in the NavigationUrl property I use a string.Format method to create a parameterized url, to pass for the browser, then second repeater is populated according to the value passed in the url which is originally passed by the first repeater's hyperlink. this is my sample code : [URL]
The subject is explanatory, but here are some details:
I want to update a repeater when SelectedIndex value changes for a dropdown list. The problem is Nothing happens.
My aspx page is present in a nested master page. and neither autopostback works nor update panel. i have set the AsyncPostBack trigger on SelectedIndexChange event.
Please let me know what am i doing wrong or what am i missing.
PS: I have never worked on ajax before so I might have overlooked something.
I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?
I have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?
i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?
I have one repeater and one gridview, i want to bind my repeater when link button is clicked which is inside repeater, i user itemCommand but its not working....
