How do I use JQuery to render the array on ASP.NET page? More precisely, what kind of HTML template do I need to set to stuff the JSON with JQuey?

While in constructor i am gettine error, Aobj(0).type is not initialized, it says that Object reference not set to an instance of an object. how to initialize my objects?
My brain doesn't seem to be working today. I googled around for this and just couldn't find it, which seems kind of strange since this is such a basic question that I can typically find out very quickly.
I'm trying to create an array of DateTime objects. I can't use a List.
DateTime[] dates
dates[0] = Convert.ToDateTime("12/01/2009");
dates[1] = DateTime.Now;
However, I get an error, stating use of unassigned local variable.
In the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List);
In the Controller I build a viewModel with the data from this session
[Code]....
and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item.
[Code]....
When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList).
return View("view.ascx", viewModel);
When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way.
I'm trying to add Div Objects to an array and trying to access them later when I call my loadViews function. All of my alerts fire, in the proper order, but the array m_Divs is always of length 0.
I'm re-registering the script each time on Page_Load, due to it throwing an "Error: Object expected" after each page_load when trying to call the javascript if I don't.

I have a gridview control that displays expenses claims received from clients. I have a template field that contains a checkbox - if this is ticked, a value from the gridview is added to a variable and this is outputted to a label control.
What I then want to do is to update the database according to which row has been ticked. I have so far the following code that adds each value to an array, which I was then hoping to access in the sql query i.e. Update table set value = value where id = (id's added to array)..
Code as follows - so far I'm just displaying the count of values in the array to make sure they are actually being added:

For some reason the following JSON string creates the correct number of records in the custom objects array, but does NOT populate the objects in the array with and values.
[code]....
MemoryStream export = new MemoryStream();
iCalendarSerializer serializer = new iCalendarSerializer(iCal);
serializer.Serialize(export,System.Text.Encoding.UTF8);
return export;
so I am using the C# DDay.iCal library for exporting my calendars. Serialize takes in a "stream" so I passed it a memory stream. I now have a generic handler that calls the method that contains the above code.
public class CalendarHandler : IHttpHandler
{
private Calendar service;
private Membership membershipS;
public void ProcessRequest(HttpContext context)
{
service = new Calendar ();
membershipS = new Membership (null);
string userName = context.User.Identity.Name;
Guid userId = membershipS.GetUsersId(userName);
context.Response.ContentType = "text/calendar";
// calls the export calendar(the code that showed above that uses dDay ical.
var t = service.ExportCalendar(userId);
t.WriteTo(context.Response.OutputStream);
}
public bool IsReusable
{
get
{
return false;
}
}
}
So now I wrote the icalendar to the Outputstream. Now I have a jquery post that goes to this method and now I am not sure how to take the OutputStream result that the jquery post will get and make it popup with a save dialog box.
$('#ExportCalendar').click(function(e)
{
$.post('../Models/CalendarHandler.ashx', null, function(r)
{
});
return false;
});
I have a list of objects and I would like to create my own custom control that pages through the list using Jquery to make the Ajax calls to my pager methods. I've had some experience with Jquery but need a helping hand and I really don't want to use update panels etc. So the scenario is.....user clicks next, the C# method is called using Ajax, the code gets the relevant data and sends re-populates the UI with the next item in the list.
View 2 RepliesI have a dynamic page which has repeating input text fields and is build using Jquery. I use C#.net to get the data to be displayed on the input fields. My question is on how do I handle single Quotes and double quotes while rendering the input field. I create jquery string on page render and uses that to render the input fields on the page. But if any of the input fields contains a html tag with double quotes then it screws up the whole page. Let me know I this make sense or need more explanation.

I have a very unique problem, humm i think. I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce');
- the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable. is there anything else i can do i really would like use this effect.
P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.
I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.
I have tried searching for the answer but have failed to get any insight into this problem. Look at the following two examples. [URL] (JQuery modal dialog without <input> element) Above pages have very simple JQuery modal dialog, whihc displays correctly in IE, Chrome, Safari and Opera. Unfortunately, Firefox does not display the modal dialog with <input> correctly. It displays the other one correctly. I have tried the following without resolution to this peculiar problem:
- Changed doctype
- Used <table> to enclose <input>
- Used <div> to enclose <input>
- Used all possible CSS display attributes for <input>
.I am using VS2010 Ultimate in an out of the box HelloWorld MVC2 ProjectI am using JQuery 1.4.1I have the following code in my View:
function TestStringArray() {
var stringArray = new Array();
stringArray[0] = "item1";
[code]...
Forgetting my controller actually needs to return a Json result (I have a break on the return View() line), the values parameter is null. When I pass in a single string (change the type from List<String> to String in the controller, pass in a single string value from the View), it works fine. Looking at Fiddler, the array is passing the multiple values.I did some research and people are suggesting JSON.Stringify ion the JSON2 library, the JSON.NEt library, etc... Do I really need extra libraries? Microsoft didn't think of this scenario for out of the box? I assume the problem is any kind of complex type.
I have the following code:
<script type="text/javascript">
var checksSinceLastPostBack = new Array();
function clientSelectedIndexChanged(sender, eventArgs) {
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
var serializedCheckData = checksSinceLastPostBack.serializeArray();
if (ajaxManager != null)
ajaxManager.ajaxRequest(serializedCheckData);
}
</script>
The
var serializedCheckData = checksSinceLastPostBack.serializeArray();
doesn't seem to work. Am I misunderstanding this?
Also if this works, how would I deserialize it in the code behind?
In my web form I have a search box. The user enters a string, and once the search button is clicked, I pass the value from my .js file to my .cs file and do some processing to get the results. Up to this point everything is fine, but now I dont know how to get my results back to my .js page. The serach results at this point are in a dataset, and also in an multidimensional array. I have a multi array because I need to pass back the code and description of the items found.
[Code]....
At this point I have used the passed string 'value' to get my required code/descriptions, but i'm not sure how/if I can get either the Dataset or multidimensional array back to my .js page
I am geting a json value with multiple stateid amd more statid are multiple,but I want stateid only unique(distinct) in jquery array.
View 2 RepliesWhat I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"]
jquery Code so far:
$("#saveBtn").click(function (e) {
e.preventDefault();
$("#addPanel").slideUp(300);
//Perform Save Operation
var saveString = "";
$("#addTable tbody>tr").each(function () {
var o = $(this).find(".hsaorder").val();
var n = $(this).find(".hsaname").val();
var l = $(this).find(".hsalink").val();
saveString += n + "|" + l + "|" + o ;
});
////// Create Array here or some other method?
$.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE});
// Remove all but top table element to return to original state
$("#addTable tbody>tr").not("#addTable tbody>tr:first").remove();
});
I'm using jqPlot and I need to turn this JSON which I receive from a WCF service:
[{ "x": 2, "y": 3 }, { "x": 25, "y": 34 }]
into this array or arrays:
[[2,3],[25,34]]
