Data Controls :: Return Json Data From Web Method To JQuery
Mar 26, 2016
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 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 use JSon to return allot of results when building a website, but find myself writing a a lot of code like this:
[Code]....
and then simply call this function with whatever IEnumerable results i have my question is would i be on the right lines here, what would be the best possible way to do this as it makes no sense to be writing in MVC and OOP but to keep rewriting code to just FROM ?
I am trying to return some data as json from an action method.
I have an employee object that looks like this:
public class Employee { public int EmployeeID {get; set;} public string FirstName {get; set;} public string LastName {get; set;} //Other irrelevant properties }
Then I have a view model as follows
public Class EmployeeViewModel { public Employee Supervisor{get; set;} public List<EmployeeViewModel> Employees }
I need to return a json object that looks exactly like this:
For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.
How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.
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] .....
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 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.
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
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.
I am binding Gridview using json (first Gridview),which have some column with linkbutton. I want to bind other gridview(second Gridview) using json on click of Linkbutton inside first gridview . how to fire json on linkbutton click event ?
I want to add gridview row data into to data base I am doing it perfectly.My problem is that want all gridview row data save and then web method should be called but in my cause one gridview data save in array then call webmethod,then other row data save in array then call webmethod called this process should be so on.But I want it webmethod should be called when all gridview row save in array.
Follwing code
Jquery <script type="text/javascript"> $(function () { $("[id*=btnSubmit]").bind("click", function () { var Customer = {};
I have .aspx page methods with return type of string, which work great. I am using some jQuery ajax, and some .NET Ajax "PageMethods.methodName" syntax from the client side to successfully call these page methods. I need to return xml from a page method.... I would LOVE to be able to return system.Xml.Linq.XElement type from page method. I get a serialization circular reference error when I attempt to return XElement or XDocument. I don't really want to return XML.ToString() to client, and then convert string to xml in javascript. What return page method return type(s) would allow me to retrieve xml with jQuery ajax call? I know json is the alternative, but will not give me what I need this time.
