AJAX :: Timer And Update Panel Stops Working After Several Hours?
Nov 11, 2010
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?
the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near 'DOCTYPE html PUB'."
Code on the dataURL_Infrasturcture_Capacity.aspx page:
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?
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 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:
Asp.Net AJAX Timer control stops ticking when I right click on the page. Actually i am updating a label using timer control for every second. When I right click on the page the label is not getting updated. I mean the timer stops ticking.
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
I have a test page with links that open a panel modally (using AJAXControlToolkit: ModalPopupExtender). I am using an update panel. After clicking any of the links about 10 times, the popup is shown buried under the links (and is not accessible). When I limit the content on the page, the number of times is extended. My thought is that this may be a "data limit" in relation to the update panel, as this works fine when the update panel is removed. I would love to post the code, but this form won't let me. I can certainly send the webform if anyone is interested.
I want to create a searching work to fill the gridview detail acc to seach params.. When we enter text into search textbox it fills the grid, that works filne without postback. After this i have to fill the form values accroding to link clicked in Gridview. I uses the updatapanel in grid like
When the grid fills it doesnt fill my form... why it happens.. i used the Updatapanels multiple as well.. If i use the Updatepanel in whole.. it may flicker while filling in the form values.
I am having a treeview in Masterpage,all tree items are associated with different page,when i click on any of the tree item,i the respective page should be displayed in the ContentPlaceHolder of the masterpage without postback,
i kept the treeview and the contentplaceholder in the updatepanel,still it is not working,means entire page is posting back to server
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
