I am currently working on an ASP.NET project, where I am using C# as my default language. I have an .aspx page, where I have an AJAX Script Manager and an AJAX timer. When that page first initializes, it does a pretty costly operation (parses a .csv file), which I only need to do once. However, every time the Timer tick takes place, Page_Init is fired again. Is there any way to correct it?

View 3 Repliesi have three textboxes in a page and one datagird and 1 timer control, i have 2 update panels.
i placed (all textboxes) in one update panel and i placed (data gird and timer control) in an other update panel, because i want to reset or clear all fields when cancel button is clicked so that update panel should be updated,and where timer control tick event is fired i rebind the gird or refresh the gird, i have done this and it works properly but problem is that when i am going to write some text in any textbox or i want to focus on any text box it should lost focus when timer control tick event is fired so how can i maintain focus, or even how can i get focus of current control and after firing of timer control tick event i should reassing focus of such control
my code is below

how can we retain the field values during ajax timer tick which is placed in update
View 3 RepliesI've got a page with a Timer that is being used as a trigger on an UpdatePanel. The page also contains a TabContainer and several TabPanels. Look at this question for more information. Basically, I've got an UpdatePanel as the element in each TabPanel's ContentTemplate, and the UpdatePanel is triggered by the Timer.My page displays data by reading a database on each tick. I've got the following code running on each Timer.Tick in my codebehind:

View 9 RepliesI'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.
I have an update panel that has a timer set as the AsyncPostBackTrigger.In this Update Panel I have a repeater and 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 tickedI have tried debugging and this is what seems to be happening, either way it takes ages for the button click to actually fire.
View 3 RepliesI'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.
During Asynchronous postback (Ajax) will Page_PreInt() ,Page_Init(),Page_Load() events fire again?
View 1 RepliesVS2010 ( 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 an ASP.NET form with several update panels. All works great.I use a timer and have it handle some periodic upates. That works correctly too. However, I appear to get an error when I leave the page open running in the debugger. Specifically the above JScript error 12030.I'm not clear how to find the source but I assume it is because my page has logged out. If I refresh I go back to my login page.So, does this sound like the cause? If so, how to I address this?

I've got the an bit of ajax and the succeed runs twice. I've got a global var that I used to keep track.
Code:
var counter = 0
$('#txtLookupText').keyup(function(event) {
$(document).ready(function() {
});
$.ajax({
type: "POST",
url: 'ContactLookup.aspx/LookupContacts',
data: "{'inputStr': '" + $('#txtLookupText').val() + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
AjaxSucceeded(msg);
},
error: AjaxFailed
});
});
function AjaxSucceeded(result) {
if (result.hasOwnProperty("d")) { result = result.d; }
var li = ''
for (i = 0; i < result.length; i++) {
li += result[i].FirstName + ' ' + result[i].LastName + '
}
counter += 1
alert(counter)
}
function AjaxFailed(result) {
alert(result.status + ' ' + result.statusText);
}
I moved the counter to the POST and only got one alert box. In the succeed, I get 2 alert boxes in succession.
I'm new to ASP.NET AJAX AsyncFileUpload so I've created an aspx page to test it but it seems there's some bug with that control because the server side UploadedComplete event does not fire.
the aspx :
<form id="form1" runat="server" method="post" enctype="multipart/form-data">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager> [code]....
in Foo.aspx
I have:
<asp:ScriptManager ID="ScriptManager1" runat="server" EnableHistory="True" EnableScriptGlobalization="True" EnablePageMethods="true"/>
<asp:TextBox ID="ATextBox" CssClass="textfield"
runat="server" />[code]....
now the problem is eventhough they seem identical to me ONLY GetBCompletionList get called and NEVER GetACompletionList
I am trying to use a RegularExpressionValidator for email ID text box. Everything works fine till I add an AJAX TextBoxWatermarkExtender for the same text box. I have given the WatermarkText="Email" for the text box. When I push the submit button, the RegularExpressionValidator fires and says Invalid Email ID. When I clear the same text box, no issues and the records are saved.I strongly suspect that the RegularExpressionValidator is taking the text of the watermark, ie "Email" as an invalid email ID. To test this I gave the text as "someone@website.com" for the TextBoxWatermarkExtender and it did not fire the RegularExpressionValidator.

I have 2 Textboxes in a Master Page with AutoCompleteExtender. But one of them fires at a time. I have tried putting them into separate webservices but that didn't work. I initially tried just making them a page method but that didn't work at all (My guess is ServicePath can't read .Master instead of .aspx properly)
<asp:TextBox ID="tbSearch" runat="server" Width="300" AutoComplete="off" Height="20" MaxLength="20"></asp:TextBox>

I have two updatepanel in a page which use a master page. the two updatepanels update mode is conditional
1st updatepanel update mode = conditional and childreenAstrriger = false
2nd updatepanel update mode = conditional
When i click any element in the fist updatepanel it update the second update panel with .Update() method.
When i click second update panel only second one will update (its ok).
All Works fine when i run from server as i excepted.
But when i run from visual studio(8) the first update panel works normally, but when i clicked any element in the second update panel, I put a break point in _PageLoad(), i notified that _PageLoad() events fire twice. First time it is as NotIsPostBack and in the second time as IsPostBack (what i excepted is single _PageLoad() events fires and is IsPostBack but this was not what when i run from VS(8) but from server all things ok) (i have a grid in second update panel and it have preRender event also with RowCommand , updating...etc.)
I want to clear the textbox control in the modalpoput at a time of showing it, but i dont know which event fires while ModalpopupExtender show time.

I have created an AJAX Server Control Extender which uses the Sys.Timer-object in the client behavior. It worked at first, but suddenly I started to get "Microsoft JScript runtime error: Object expected" when running the page with the extender. When debugging, I see that the line - this._timer = new Sys.Timer(); - in my .js-file which fires the error is the bold line in this function:
