Using JQuery And JSON To Consume Server-Side Asynchronous Web Methods?

Jan 27, 2011

I defined two webservices calls in ASP.NET:

1.BeginLengthyProcedure and EndLengthyProcedure (Asynchronous web method)
2.LengthProcedureSync

namespace ServiceDemo
{
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class AsyncWebService : System.Web.Services.WebService
{
public delegate string LengthyProcedureAsyncStub(int milliseconds);......

How To Fire Server-side Methods With JQuery

Jun 8, 2010

I have a large application and I'm going to enabling short-cut key for it. I'd find 2 JQuery plug-ins (demo plug-in 1 - Demo plug-in 2) that do this for me. you can find both of them in this post in StackOverFlowMy application is a completed one and I'm goining to add some functionality to it so I don't want towrite code again.So as a short-cut is just catching a key combination, I'm wonder how can I call the server methods which a short-cut key should fire?

Update: here is the scenario. When User press CTRL+Del the GridView1_OnDeleteCommand so I have this
protected void grdDocumentRows_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
try
{
DeleteRow(grdDocumentRows.DataKeys[e.Item.ItemIndex].ToString());
[code]...

JQuery :: Submitting Form With JSON To Server Side Script

Jan 22, 2011

I was wondering if there is an easy way to submit a form or a collection of fields with jquery and json to a C# server-side script. I was thinking of a script that retrieves all data from elements with an attribute called 'form' (yes, we just add a new attribute to for example a textbox or textarea). Thus, the script searches for all form attributes with form='myform' and then submits the data as an form object. In server-side code we know how to deal with the data. Does someone has such a script? Or can I inspire someone to develop such a script? (I have the idea, not the skills) ..also, sessionstate needs to be available (cookie).

How To Consume JSON From A Web Service

Oct 7, 2010

We have a web application providing a service using a simple REST interface (GET/POST methods) and returning results in JSON format.

A client wants to use the service from an ASP application (I assume ASP.NET) and asks for example code.

Is there any standard/widely-acceptable procedure for consuming JSON based web services from an ASP.NET application? I'm not familiar with the .NET framework, but can work my way through C#.

Passing A JSON Object To A Function On Server Side?

Jun 4, 2010

I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.

So I create jSON object on client-side

var myJsonObject = {
"arg1": var1,
"arg2": var2
}

and pass it in to

WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);

When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]

So in following server-side function, the argument value is [object Object]

public void RaiseCallbackEvent(string jsonObj)

I was expecting a string representation of JSON object. How do I pass in a string representation?

Jquery - Options For Page With Matching Client-side And Server-side Markup?

Oct 17, 2010

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).

What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

JQuery :: JQuery Hide Div, Server-side Button Onclick Not Firing In IE?

Feb 9, 2011

I have 2 update panels where the server-side button (in a jQuery accordion) in the first update panel should update the second update panel.When the button is clicked, jQuery hides the accordion and displays a results div. This all works fine client side to be fair to IE. The server-side onclick event does not fire though in IE. In Firefox it does! The first update panel is displayed below, here the "btnGenerateReport" event should fire server side.

[Code]....

To add confusion ... if I comment out '$accordion.toggle($effect);' lines then the second update panel does get updated.I'm not sure what other information I can give here. I'm stumped as to why this works with Firefox and not IE.
