In this article we will register our web
service in Srcipt-manager Control. In addition we will modify service method,
so it accessible from client. Finally we will write some java script code and
display value return from service as output..
Before reading this article, I strongly recommend to read my previous article
on web-services in ASP.. on below link
www.c-sharpcorner.com/Blogs/12612/web-services-in-Asp-Net.aspx.
1. The first thing you need to do is create new Web site in visual studio.
2. Check App_Code folder is there, if not then right click on root directory-->
Add ASP.Net Folder-->Click on App_Code...
3. Create folder and name it as Web-services.
4. Right Click on Webservices Folder --->Add New Item--->Select web service and
name it as Name.asmx as shown below
Click add to add the service to the site. This will add .asmx file to your
webservices folder and code behind file in App-Code folder
5. Open the Name.cs file from App_Code folder and change the helloworld method as shown below
[WebMethod]
public string HelloWorld(string name)
{
return "Hello :" + name + " Welcome to Asp.Net";
}
6. Save your all changes , right click on Name.asmx in the soln explorer, choose
view in browser. you should see your service is running.
7. Click on Helloworld link and type your name and click on invoke button . A
new window showing xml that has been return by web service
8. Open Name.cs from App-Code folder.
To allow this Web Service to be called from script, using ASP.NET AJAX,
uncomment the following line.
[System.Web.Script.Services.ScriptService]
public
class Name :
System.Web.Services.WebService {
9. Next step is creating page that uses service..So add one page to your web
site
Drag and drop Input text and Input Button from
toolBox under HTML Control and Scrip-manager from Ajax extensions as shown below
Note: The Script-Manager control serves as the bridge between the client page
and server.It manages the script resource such as JavaScript file and take care
of partial page update.
10. Within the script-manager add add <Service> element that in turn contains
service-reference for setting path of service as shown below
