No one is going to download your code & work it for you. Better include the screenshot link & post relevant code in your question.

ٍSir;
you are duplicating the textbox each time with the same id, which is invalid.
then you retrieve the value of the first element in the document with that id, this would return the same value each time.
instead you can give the textbox an unique id each time or use document.getElementsByName() (you should then add the attribute name instead id in the textbox tag).

Hi,

I have a deployment environment that contains 2 server A and B both are configured to use a load balance system. Now the connection has been upgraded to SSL and we need to install certificate to both system. Can you please help me informing,

1. Do I need to have same certificated installed in both system (A and B) or different certificate in both (A contains a certificate and B contains another
certificate)

Thanks in advance.

Thanks,

You should be using different certificates.

As well - each certificate should be created with that server name.

What load balancer? Big IP?

Are you using sticky sessions? (cookie persistence included?)

Thanks Rene. I am yet to get some information from actual environment (information such as some more details about load balancer and if in our target environment we have sticky session or not. I will get back as soon as I get some of this information.

Thanks,

WEB API Serialization Problem?

Kevin Marois7-Apr-14 9:38

I'm VERY new to Web API and Web development in general.

I have a GetClient method in my controller.

[HttpGet]
public Response GetClient(int entityId)
{
	return BO.GetClient(entityId);
}

It returns a Response object:

[DataContract]
[Serializable]
public class Response
{
    [DataMember]
    public object Data { get; set; }

    [DataMember]
    public Result Result { get; set; }

    [DataMember]
    public string Message { get; set; }

    private Exception _Exception;
    [DataMember]
    public Exception Exception
    {
        get { return _Exception; }
        set
        {
            if (_Exception != value)
            {
                _Exception = value;

                Message = _Exception.Message;
                Result = Result.Failure;
                Data = null;
            }
        }
    }
}

When I call it I get back a null Response object. If I paste the ResponseUri into a browser it comes back with:

{"Data":{"ClientName":"MyClient","IsDirty":false,"RowState":4,"Id":1,"UniqueId":"00000000-0000-0000-0000-000000000000","IsActive":true,"IsDeleted":false,"CreatedByEmployee":null,"CreatedDate":null,"ModifiedByEmployee":null,
"ModifiedDate":null},"Result":0,"Message":"","Exception":null}

So it looks like some kind of serialization problem. I have no idea how to fix this,. Any thoughts on what to do:

Thanks

How are you calling it? Are you specifying the same accept headers as the browser?

Try using Fiddler[^] to capture the working and broken requests to see what's different.

None of the requests work. The data DOES come back from the back end into the controller, it's just that the objects don't appear to be serialized when they get passed to the front end.

So which is it? If you paste the URL into the browser, does it come back with data, or does it not work? Confused | :confused:

My UI calls through the proxy into the controllers, which calls to the DAL. The DAL returns a populated Response object back to the controllers. When the Responses get back to the proxy, they are always null.

If I paste the URI's into IE, I get back JSON with data in it. So it looks like some kind of serialization problem.

If it's not broken, fix it until it is

I am still stuck on this. I thought I might have solved it, but it's stil bot working.

None of my controller methods are deserializing the return objects. All methods return null.

However, if I paste the URL into a browser, it displays the JSON correctly. I have no clue what's wrong, and I don't know how to debugs this. I get no errors or other problem indicators.

Any ideas on what's wrong? Can you point me in the right direction for debugging this?

Thanks

[UPDATE]
I figured out the problem...

I'm using custom response objects that I'm returning from the all the way back to the UI. The base Response object has a property to hold the data. It is of type object, which from what I'm seeing in Google searches, cannot be deserialized. So the entire result object is being returned as null.

Any thoughts on what to do?

If it's not broken, fix it until it is

How about making the base Response class a generic class, so that you have a strongly-typed property for your data?

OAuth 2.0 SSL Certificate Requirements

Jammer4-Apr-14 1:15

4-Apr-14 1:15

I'm about to deploy an application that comprises a web site (ASP.NET MVC) and an API (WebAPI) using OAuth 2.0 for security.

Currently all the calls to the API are done server side by the web site and will be configured to use SSL as will the web site itself.

My question is about the certificate requirements, it appears that this isn't really detailed in the spec so thought I'd throw this out for discussion.

What are peoples thoughts on the use of SSL certificates in this scenario?

Do you require multiple certificates? One for securing the site and another separate one used for dealing with the token creation or would it be safe/good practice to use a single certificate?

Thanks,

Jammer

Telerik / Kendo grid using t-no-data

littleGreenDude2-Apr-14 3:24

The following function used to work with the Telerik grid, but now that we have upgraded to Kendo, it no longer works.

JavaScript

function Grid_onLoad(e) {
  $('.t-no-data td').text('Loading Records...');

}

I expected Telerik to replace the .t-no-data class reference with .k-no-data, but they haven't. The .t-no-data reference is still used and appears in the document, but the function no longer behaves the same. The 'Loading Records...' message is never displayed.

Anybody using t-no-data for a similar purpose?

I got the answer, and I'm posting it here in case anybody else needs to do something similar.

Move the loading message to the tbody

dataSource = new kendo.data.DataSource({
            requestStart: function(){ 
              $("#grid tbody").text("Loading data...");
            },

Hi All,
I am trying to load large XML file(222 MB) using javascript for HTML format. It is taking a lot of time.
Can anyone suggest me to make it more efficient?
Any sample is more appreciated.

I am using something like below,

var xmlDoc=null;
if (window.ActiveXObject) //IE 8,9
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
else if (document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument ("","",null);
}
else
{
alert('Your browser cannot handle this script');
}

if (xmlDoc!=null)
{
xmlDoc.async=false;
xmlDoc.load('Load.xml'); // Large xml file
}

Firstly, don't duplication your question over many forums.

Second, considering the size of the file, and what you are trying to do with the thing, why are you surprised it is taking a rather long period of time.

Optimize HTML markup size: How to exclude Microdata+ARIA?

Sergejack30-Mar-14 21:25

Sergejack

30-Mar-14 21:25

I get that Microdata and ARIA are the future for better integration of webpages.

Yet, in the present day there's a strong disadvantage of using them: filesize for mobile devices which bandwidth is costly.
However cheap it might be for you, I swear in some countries/areas every megabit matters for the billing.

I'd like to offer "my" websites' visitors an option to get light "Microdata/ARIA free" versions of the pages.

Do you know techniques to conditionally exclude all Microdata+ARIA markup before sending it to the end users?
FYI: I'll planning to do that using Wordpress PHP at first.

Did you mean "javascript" by "HTML"?

If so, you could use JQuery, especially $.getJSON https://api.jquery.com/jQuery.getJSON/[^]

yes.

I got it and solved the problem

but I have one issue.

my json url has an API key which I don't want it to be shown to the user?

is it possible to encrypt it or hide it?

this is my code:

JavaScript

<script type="text/javascript">
$(document).ready(function()
{
	$.ajax({
		url : "http://api.wunderground.com/api/xxxxxxxxx/geolookup/conditions/q/Bahrain.json",
		dataType : "jsonp",
		success : function(parsed_json) {
		var location = parsed_json['location']['city'];
		var icon_url = parsed_json['current_observation']['icon_url'];
		var weather = parsed_json['current_observation']['weather'];
		var temp_c = parsed_json['current_observation']['temp_c'];
		var feelslike_c = parsed_json['current_observation']['feelslike_c'];
		var relative_humidity = parsed_json['current_observation']['relative_humidity'];
		var wind_kph = parsed_json['current_observation']['wind_kph'];
		
		$("#imgWeather").attr("src", icon_url);
		$("#lblWeather").text(weather);
		$("#lblTempC").text(temp_c + " C");
		$("#lblFeelsLike").text("Feels Like " + feelslike_c);
		$("#lblHumidity").text(relative_humidity);
		$("#lblWind").text(wind_kph);
		}
	});
});
