Web Forms :: Timer Control - Can't Update Values Outside Of Panel
Nov 2, 2010
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'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 hidden control in update panel with a OKÂ button
on OK button currently i have a called a client side script whic has button1 click event with server side ( this procedure was foloowed for doing something else)
1) whts the difference between using directly serverside click event on OK button & using as above
2) currently the values from the hidden controls gets appended even after having the postback  <asp:Button runat="server" ID="btnok" Text="OK" OnClientClick="setvalues()" /> function setvalues() { document.getElementById('<%=button1.ClientID %>').click(); }doesnot the controls in update panel gets cleared in postback??
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?
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 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 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 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 trying to get my head around the ASP timer control. What I am trying to achieve is to get a page to reload every 60 seconds but change the url querystring everytime between 3 values
i.e. scroll through server/page.aspx?value=1 server/page.aspx?value=2 server/page.aspx?value=3
how I have though to do this is to use ASP code to grab the querystring value, and then create the next url. But I am having trouble passing that newly created url to a refresh control. im guessing HTML meta refresh is out of the question as I am using a variable. So from what I can see my option is to use the ASP timer control to count down (after the page has loaded) and after 60seconds load the next url.
ERROR:Error 1 Cannot create an object of type 'System.Int32' from its string representation 'Convert.ToInt32(ViewState["RefreshInterval"])' for the 'Interval' property.
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 have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
I have a ListView control that is inside of an update panel. I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button. The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected. I then can go to another page, come back and the new data is there. I'm not sure what I missing. Please see the code below.
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
