Call webservice from javascript

admin — Sun, 11 Oct 2009 17:13:04 +0000

1. VS 2005 – create new website with ASP.NET Ajax-Enabled Website , then create WebService.asmx

using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Script.Services;
///

/// Summary description for WebService
///

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService] // <== [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {

public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}[WebMethod]

public string HelloWorld() {
return “Hello World“;
}[WebMethod]

public string GetDateTimeFromServer()
{
return DateTime.Now.ToString();
}
}

==============================================

2. Create JScript.js

// JScript File

function GetDateTimeFromServer()
{
WebService.GetDateTimeFromServer(OnSuccess, OnFail);
}

function OnSuccess(e){
document.getElementById(‘LabelDateTime‘).innerHTML = e;
}

function OnFail(e){
document.getElementById(‘LabelDateTime‘).innerHTML = e;
}

=================================================

3. Create Default.aspx

<head runat=”server”>
<title>Untitled Pagetitle>
<script src=”JScript.js” type=”text/javascript”>script>
head>
<body>
<form id=”form1″ runat=”server”>
<div>
<asp:ScriptManager ID=”ScriptManager1″ runat=”server”>
<Services>
<asp:ServiceReference Path=”WebService.asmx” />
Services>
asp:ScriptManager>
<br />
<button onclick=”GetDateTimeFromServer();”>
– Show server time –
button>
<br />
<label id=”LabelDateTime”>
label>
div>
form>
body>
html>

Asp.net Permalinks Using URL Rewriting

admin — Fri, 09 Oct 2009 04:27:41 +0000

A Permalink is a permanent link which points to a particular blog entry or forum entry. For example the permalink for this blog article is http://csharp-codesamples.com/2009/03/aspnet-permalinks-using-url-rewriting.

This does not mean that a physical page is created for each blog entry. Instead a single page shows the data for multiple blogs articles dynamically based on some query string.

But all pages in asp.net end with a .aspx extension and if we pass a query string to the page it will look something like Page.aspx?query=test. These links are not very search engine friendly.

This article describes a simple method to create permalinks and improve your asp.net websites search engine optimization using URL rewriting without the use of custom handlers.

ASP.NET Dynamic Data Preview #7: How Do I Use a DynamicControl in ListView and DetailsView Controls?

admin — Wed, 30 Sep 2009 07:15:56 +0000

This video compares the same application written twice, once with Dynamic Data and once without. In the process, you add DynamicControl objects to ListView and DetailsView controls.
