Javascript Crash / Ajax In IE After 5 Times?
Apr 8, 2010
a look at this site.maimei.chAfter 5 times opening a new site via ajax (fancybox) it crashes in IE?ne little thing is that i load a whole asp.net site via ajax in the new window. so viewstate and other overhead is there twice after. could this be the problem? if yes, why just after 5 times?.is it possible to call just the content of an specific element via ajax? may be just the innerhtml of the body element of the called site?

I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.

I am using a document.getElementById("val").click() to invoke a click event, but it keeps firing multiple times.
Here I add the eventHandler
try {
//add mousedown event handler to navigation buttons
addEventHandler(oPrevArrow, "mousedown", handlePrevDayClick);
addEventHandler(oNextArrow, "mousedown", handleNextDayClick);
addEventHandler(oLogout, "mousedown", handleLogoutClick);
}
catch (err) {
}
In the click event i am performing a "auto click"
function handleNextDayClick(e) {
e = e || window.event;
stopEvent(e);
document.getElementById("btn_nextday").click();
}
NB: the button that is auto-clicked calls a method in the ASP.NET Code-Behind

I'm using the local database functionality in Chrome and Safari and what I do when I want to save this to a remote database is to create a hidden textfield and then using JSON to stringify each row. In the code behind I then parse each JSON object and insert it into the list. What I want to do now is to delete these rows from the local database. I have a JavaScript function called deletePatient:

My basic structure is that I have a table on a page, which I want to reload without refreshing the entire page. So on clicking a button on the page it fires of this:
function RefreshMissionsAjax() {
//fade out the old table.
$(clientID('MissionsDisplay')).fadeOut(500);
//request the new value from the page (calls the GetIncompleteMissions() method in the MissionViewer.aspx.cs page)
$.ajax({
type: "POST",
url: "MissionViewer.aspx/GetIncompleteMissions",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$(clientID('MissionsDisplay')).html(msg.d);
$(clientID('MissionsDisplay')).fadeIn(500);
},
error: function (xhr, ajaxOptions, thrownError) {
$(clientID('MissionsDisplay')).html('An error occured while trying to refresh the page data.');
$(clientID('MissionsDisplay')).fadeIn(500);
}
});
}
And I have in the code bedind of an aspx page:
[WebMethod]
public static string GetIncompleteMissions()
{
return GetHTMLTable();
}
This method just grabs some data, and creates a html table - nothing too fancy. When the returned table is small (a dozen rows or less) then it works like a charm. But when it gets larger, it takes a long long time. At 100 rows it can take 5 minutes to render the table. At 1000 rows I have left it for 30 minutes and nothing will happen after the fadeout. (NB - it loads fairly quickly on the pageload, before the ajax refresh is used, so it is not the actual server side creation of the table thats the problem).
This is my first real attempt at doing something like this, so I dont know if this is the best way to do it - it was just something i pieced together that worked great when i was testing with small datasets. Now, not so much.

Our ASP.NET 2 web application handles exceptions very elegantly. We catch exceptions in Global ASAX in Application_Error. From there we log the exception and we show a friendly message to the user.However, this morning we deployed the latest version of our site. It ran ok for half an hour, but then the App Pool crashed. The site did not come back up until we restored the previous release.How can I make the app pool crash and skip the normal exception handler? I'm trying to replicate this problem, but with no luck so far.Update: we found the solution. One of our pages was screenscraping another page. But the URL was configured incorrectly and the page ended up screenscraping itself infinitely, thus causing a stack overflow exception.

I have a very peculiar problem that I've been wrapping my head around and I just can't figure it out. I have an updatepanel. Inside that I have a TabContainer. And inside that I have three TabPanels, each of which has checkboxes. Sometimes (and it happens often enough that I can easily reproduce it, but strangely may not happen with the same exact steps), when I click on different tabs or click on checkboxes inside the tabpanels (basically when I do an AJAX async postback), the request takes about a few minutes, after which the request just stops. Looking at the Firefox error console, I see this popping up after a few minutes...
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0 Now, the asyncpostbacktimeout property for the ToolkitScriptManager is set at 360000, which is 6000 minutes, so the problem has nothing to do with that setting. In IE, I never have this problem and the AJAX requests are instantaneous and smooth, no delays. So this isn't a network or database lag issue. Something to do with how AJAX is run in Firefox. Why is it that sometimes, an AJAX request in Firefox takes a few minutes and just stops processing the request? And once again, the steps to reproduce this problem may not be the same every time, it seems random - very strange. Google searches have yielded very little help on this. I've tried things like extending the timeout property (which again has nothing to do with this), setting Response.Cache.SetNoStore() everywhere. Is there a crude workaround I can do (at this point, I'm willing to settle for a workaround). I just don't know anymore.

When the popup opens, the following code is run:
.....
if (window.attachEvent) {
$("#rblQuickPick").change(function () {
//ClickQuickPick();
alert("something changed!");
});
.....
ClickQuickPick() is the code I will eventually run, but I put in the Alert for testing.
The issue is that when the popup extender opens, and I click an item, I get the alert once. If I click another choice I get the alert twice. If I click another choice I get the alert three times, etc.
What is triggering the event to repeat, and how do I stop it?

I have a masterpage setup, with a pageLoad in the topmost masterpage, which calls pageLoad2 for nested masterpages which calls pageLoad3 for content pages.
In my content page I have a jquery click event and in my nested masterpage I have a web user control.
Whenever I use the user control in the nested masterpage, it rebinds the click event in the content page (undoubtedly because the pageLoad3 is called again), but this makes the click event fire twice on a single click. The problem gets worse the higher up masterpages you go (eg. fires 3 times if user control from topmost masterpage is called).
how to make sure it only binds the jquery events once?

I have a InsertCommand function i am using to insert the dropdownlist in my updatepanel. When the Add button is clicked. It adds the record multiple times. Am not sure why it does this. Here is my code.
Dim Bank_number
As
DropDownList = UpdatePanel1.FindControl("ddlbank")Dim
NoteAccountNumber As
DropDownList = UpdatePanel1.FindControl("ddlAccount")'
UpdatePanel1.ChangeMode(FormViewMode.Insert)
lblsee.Visible =
"true"
'now collect selected information on the drop down
RelationshipTest.InsertParameters(
RelationshipTest.InsertParameters(
"bank_number").DefaultValue
= ddlBank.SelectedValue.ToString"noteaccountnumber").DefaultValue
= ddlAccount.SelectedValue.ToString'Insert into db
RelationshipTest.Insert()
Also, i was woundering if any of you might know the logic behind clearing inserted data from the dropdownlist once its inserted. I am trying to make sure data is not entered mulitiple times. Unique Indexing comes to mind but thats only on the backend.

I converted a ASP.Net website to ASP.Net web app and changed the framework from 2.0 to 3.5
The web application works fine in Visual studio. However, If I compile the app in a dll, and try to reuse its middle layer in another web project, All the classes that have a static variable crash. Code like:
public static string myString = "Something";
However if I convert it to a property like this:
`public static string myString {get{return "Something";}}`

What is happening is I'm trying to process international characters, but the code is falling through (giving up?) and replacing the field with a blank (well, I guess the screenshot is at the bottom)... The customer recently asked for support for Polish characters, and gave us a list of which ones he wants added.
This is the entire function:
Code:
Protected Function chkExtchars(ByVal name As String) As String
Dim j As Integer = 0
Dim dt As New DataTable
Dim c() As Char = Nothing
Dim n As Integer
Dim nc As Char
Dim newname As String = ""
dt = HttpContext.Current.Session("xChars")
[Code] ....
But maybe it needs to be sequential? (the numbers on the far left?)

I use ASP.NET Ajax in my web site and I am monitoring the HTTP requests per each page. I am surprised by the excessive call of ScriptResource.axd with different query string variables. I am pasting a sample of HTTP trace below. The call for ScriptResource.axd take lots time percentage out of total response time. Is this by design or there is something wrong with my AJAX configuration in web.config?

Actually it is degrading the performance of the application. And the user experience becoming very poor in case of lower bandwidth.

I just deployed my first ASP app to a remote server (using SQL SErver) and some data entry forms are crashing when the associated table is empty. The PageLoad method is empty, but the error occurs before the page becomes visible. The limited run time error I see says page not found error 404. If I put a record in the table using Mgt Studio, everything is fine. The form contains two LInq data source controls that populate dropdown lists, but everything else was hand coded - no data bound controls at all.
There is no attempt to access the actual empty table until the data has been entered and the Insert button is pressed. I have made sure that the tables that use the datacontrols for dropdowns have data in them, even though this should not matter. I did not have this problem on my local machine when developing. In summary, page does not load when table is empty, even though I do not access the table when the page loads?????
This is the entire codebehind file, and yet the page cannot even seem to load.

I am trying to implement an ajax form inside of a jquery ui dialog.
I have a view with a button that opens the modal dialog form, makes an ajax call to an action that loads a partial view into the dialog. The partial view consists of a form created via Ajax.begin form. When I post the form I close the modal and update a div on my main page. This all works fine.
The problem is, the next time I open the modal and submit the form the http POST for the form is called twice. The third time I open/submit the form is submitted 3 times and so on...
It seems as if the submit button/form is bound multiple times and I cant figure out how to fix this.
Here is my code...
first the jquery call to load the ajax form partial view and create the modal...
[Code]....
here is the ajax form partial view...
[Code]....
and the js callback when the form is submitted
