Forms Data Controls :: Timer Control Timer Event Forces A Gridview Databind Every 10 Seconds?
Nov 25, 2010VS2010 ( 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 :: Trigger Event Added To Dynamic LinkButton Click Event?
Jun 25, 2010I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.

AJAX :: Timer OnTick Event Not Being Triggered?
Oct 20, 2010I am trying to modify the Interval and Enabled properties via ViewState but it is not working.
Here is my code:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
//set the default Refresh Interval to 3 seconds and enable Timer to TRUE
ViewState["TimerEnable"] = true;
ViewState["RefreshInterval"] = 3000;
}
Markup:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server"
Enabled = <%# Convert.ToBoolean(ViewState["TimerEnable"].ToString()) %>
Interval = <%# Convert.ToInt32(ViewState["RefreshInterval"].ToString()) %> >
</asp:Timer>
...
If I use Enabled = "true" and Interval = 3000, the code works just fine!

AJAX :: MultiHandleSliderExtender Not Causing Event Trigger?
Feb 4, 2010I created a MultiHandleSliderExtender on a web form. All works well with updating the two textboxes with the value. The problem is that when I switch to designer mode, I get the following error:
The code is as follows:
[Code]....
[Code]....
[Code]....
The control works and the 2 text boxes get updated, but I tried putting in an update panel with a trigger on mh_1_BoundControl but it never fired. I removed it thinking that was the cause of the error, but no luck.
Now when I add another sliderextender below it for a different value, the code throws an error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Type AjaxControlToolkit.SliderOrientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
I found this example on this site and tried implementing it but to no avail.
AJAX :: How To Programmatically Trigger An Event Handler
Mar 2, 2010I need to run a SELECT box [on]change handler after changing the selectedIndex.

The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.

AJAX :: Cascading Dropdowns Reload On Event Trigger?
Oct 15, 2010I have three cascading dropdowns and two of them need to trigger something outside of the dropdowns, so I have OnSelectedIndexChanged events on them. So as to not reload the whole page when these items are triggered, I have all of this in an Update Panel.
Everything works fine -- the only issue that the client doesn't like is that the cascading dropdowns reload on the asynchronous postback.
Web Forms :: How To Capture The Onbeforeunload Event And Trigger The Previous Button Click Event
Nov 17, 2010i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
View 6 RepliesAJAX - Client Timer Synchronous With Server Timer?
Apr 23, 2010I'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 :: How To Call The Event By Timer Based
Apr 8, 2010I have a page and on button click event, we executing the stored procedure (calculation process) .
It has to process for the large data, so it will get more time to execute.
at the end of the SP i am executing the another SP which is also process for large data.
so 2 SP's running on the button click. when i click the button it taking too much time for executing and return timeout error.
if the record is less in the table then getting result properly. now i want to split the event to execute the 2 SP's saparetely.
but the user will click the button at one time only. at that time i want to execute the SP1 and respond to the user back, Show some processing message to the user and automatically call the SP2 in the same event.
how to do this in c#.
I can't change the stored procedure. because it has to process for all the reocrds. so, in backend not possible to fine tune.
Web Forms :: How To Redirect From A System Timer Event
Oct 11, 2010I am using a System timer at the host server to determine when to redirect a client to a new URL. I had assumed that a "Response.Redirect" instruction in the timer tick event handler code would cause this to happen as it does in any client control event. Unfortunately, I get an error message that states "Response is not available in this context". What else can I do to cause the client to redirect to another URL?

View 9 RepliesWeb Forms :: Timer Tick Event Doesn't Fire In Second User Control
Jan 22, 2011I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.

State Management :: Asp:Timer OnTick Event Does Not Fire?
Dec 8, 2010I need to have a timer to count down a multiple-paged online quiz. The timer countdown should decrement consecutively on each following page. It is tricky to use javascript to maintain the timer value across multiple pages through sequences of postbacks. So, I have been searching a server-side solution and found this:
http://forums.asp.net/p/1621352/4161304.aspx (see the response by Wenchao Zeng - MSFT, the 4th post in that thread).
I created a small web application to test it out and it works great. But when I put the code into a header user control (Header.ascx) in my quiz application, the Timer control's OnTick event never fires. I put a break point in the first line of Timer1_Click, but the debugger of visual studio never gets there.
I tried this:
[Code]....
The code behind is the same (except maybe UI control names) as the one we see at the thread I referred to above. But Timer1_Click never gets executed (and hence my countdown doesn't get displayed). The CountDownTimer class works just fine because I can see from the debugger that the time value is decreasing like I want.

Trigger A JavaScript Click Event From Vb.net?
Jan 27, 2010I have a set of accordian divs (powered by the prototype library) in an asp.net page. I would like to save the state of the accordian, so when a postback event occurs, the same div is open rather than reloading the page entirely and opening the default div.
My plan was to set a page control value with the ID of the open div using the div's toggler click event function, and then fire a click event after postback calling that same div (using the value of the control holding the div ID) as the target. I'm not sure how to fire a javascript click event from vb.net however, and this sure seems like a lame workaround.
1) can you tell me how to fire a javascript click event from the vb.net codebehind page
-or-
2) is there a more elegant way to do this?
