May 7, 2015
I am trying to retrieve asp.net C# List method in JavaScript by referring Send-and-receive-JavaScript-Array-to-Web-Service-Web-Method-using-ASP.Net-AJAX ..My Code as below
Javascript
<script type = "text/javascript">
function GetAllSVGData() {
PageMethods.GetSvgElements(OnSuccessSVGElements);
}
function OnSuccessSVGElements(response) {
[code]....
My problem is JavaScript function OnSuccessSVGElements is not firing. When I put breakpoints in it is working fine in C#. C# Method Working But Alerts in javascript not working.
I want to send single json object with nested arrays through jquery ajax method.
In Code
In jquery ajax i am passing LeaveRuleMaster a single json object which holds some properties (Leavetypeid, Leavename, Leavestatus and nested array LeaveRulespecific.
In vb.net code i can receive the value of properties(Leavetypeid,Leavename,Leavestatus)
but i am receiving the LeaveRuleSpecific as nothing.
Based on the following link i tried this [URL] .....
How to return values from Webmethod to the client in JSON format? There are two static int values that i want to return.Do I need to create new object with those 2 properties and return it?The GetStatus() method is called frequently and i don't like the idea of creating a special object each time just for json formatting...
[WebMethod] public static int GetStatus() { int statusProcess,statusProcessTotal; Status.Lock.EnterReadLock(); statusProcess=Status.Process; //Static field statusProcessTotal=Status.ProcessTotal; //Static field Status.Lock.ExitReadLock(); return ... } On client side I catch the return value in : function OnSucceeded(result, userContext, methodName) (PageMethods.GetStatus(OnSucceeded, OnFailed);)
I have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?
i am new in json script.am trying to convert the database table value into json using asp.net with c#.here, am also send the response to asp.net client side.but am not receiving any response from server side.
I'm doing an jQuery AJAX POST call to a webmethod, which is working fine. If I'm passing data from the AJAX call, I normally get the data in the webmethod via webmethod parameters.
JavaScript Code: $.ajax({"dataType": "json","contentType": "application/json","type": "POST","url": "Default.aspx/GetStuff","data": JSON.stringify({"a":"data1","b":2}),"success": function (msg) { console.log(msg.d);}}); C# Code: [WebMethod]public static object GetStuff(string a, int b){ }
Is there any way I can get the data as a Dictionary or some other object, instead of having to put in individual parameters to the GetStuff() web method for each data param? It's a POST request so nothing is in Request.QueryString, and Request.Params/Request.Form doesn't contain it either.
I have a web Method in my C# that is called via Jquery ajax method. The web method should return an object back to the Jquery which will be used to populate. I have tried returning a JsonResult object, the actual object and nothing seems to work! I'm not using MVC (Unfortunately). Is there a way that I can return an object from my web method which can be used by my AJAX method? here is the link for my JQuery AJAX method [URL]
I have an Ajax function called from JQuery that goes to a webservice to return a value. I need a SIMPLE example on how I can do this. I've been going nuts with serializing and every other aspect of this topic. I need to return either an ArrayList with ONE string field or a DataTable of some kind. Either way, I'm populating it into a DropDownList. I'm willing to consider alternatives to this idea. (Background info - I get a value from a textbox and I need to run it through a DB to get an associated value or set of values). I'm being really general so that someone can show a simple example.
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?
After much head scratching as to why my returned Json string is breaking JSON.parse, I have realized that it is the returned dates that it doesn't like.
i manage to add recrod via jquery ajax call to webmethod but i want to update the dropdown list once the record is been added. i dont want to use update panel. what would be the best way of doing that.
I have a list of person objects which I want to send in response to a jquery' ajax request. I want to send the list into JSON format. The list is as follows -
List<Person> PersonList = new List<Person>(); Person Atiq = new Person("Atiq Hasan Mollah", 23, "Whassap Homie"); Person Sajib = new Person("Sajib Mamud", 24, "Chol kheye ashi"); PersonList.Add(Atiq); PersonList.Add(Sajib);
How can I convert the "PersonList" list into JSON ?
In my asp.net website I need to return data obtained from DB by adding html tags to it from a server side method,just like a webmethod returns jsonified data. I am having trouble understanding if a webmethod can serve the purpose(i.e., htmlifying the data).If not how do I acheive it?
Can my WebMethod return an XmlDocument as return type?
When I try to consume the web service I'm still not getting XML. It appears as though a reference to the method is being returned rather than say a string containing XML.
<WebMethod()> _ Public Function CustomerSearch(ByVal lastName As String, ByVal firstName As String, ByVal companyName As String, ByVal city As String, ByVal state As String, ByVal email As String) As XmlDocument ' Create XML doc Dim doc As XmlDocument = New XmlDocument() ' some more code Return doc End Function
I have an ASP.NET webservice method that returns a generics list (List'<'Construct>) serialized as JSON, using code such as this:
[WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class TestService : System.Web.Services.WebService { [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string GetOccupationListJSON(int SOCLevel) { Construct NewConstructList = new ConstructList(); DataContractJsonSerializer serializer = new DataContractJsonSerializer(ConstructList.GetType()); MemoryStream ms = new MemoryStream();
[Code]....
I assumed (from looking elsewhere) that accessing the JSON data through the index would provide me with access to the underlying object at that index, so that I can then work with it to access its properties. However, when i=0 and I do var Construct = data[i]; I get the character at the i position of the data array ([), and in the next iteration I get the second character ({). So clearly I am accessing the elements of a string array rather than the JSON data object.How do I make sure that the data returned by the webservice gets into proper JSON format, so that I can iterate through the object elements within it?
I want to return an array of javascript objects from my asp.net asmx file. ie.
variable = [ { *value1*: 'value1',[code]....
I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable.
EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.
Just ramping up on JSON and JQuery and returning data to a ASP.NET web page from a web service using Ajax. The JQuery part is pretty straight-forward. However, when trying to return JSON formatted data instead of XML from a 2.0 web service, I'm stuck. The web service does have the System.Web.Script.Services.ScriptService attribute, so I can hit it via JavaScript; however, the web service always...always...returns data in XML format, no matter if I explicitly say I want JSON as the datatype in my JQuery code. So I don't know if this is an issue with the web service or the JQuery code. I posted this here, but realize that the category could be incorrect depending on where the issue is. Is there no way to return JSON data from a 2.0 web service? It's a production web service, so I can't change the code unfortunately.
