ajax json jquery call with passing parameters using ASP.Net

If you want to load a content faster than before, you need to use ajax to load content. To get started you need to:

HTML

<div id="EventContent" class="loading"/>

SCRIPT


$.ajax({
type: "POST",
url: "RSSReader.asmx/GetRSSReader",
data:
"{controlName:'events.ascx'}",
contentType: "application/json;
charset=utf-8",
dataType: "json",
success: function(data)
{
$('#EventContent').removeClass('loading').html(data);
}
});



APP_CODE

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo
=
WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public
class RSSReader : System.Web.Services.WebService {
[WebMethod]
public
string GetRSSReader(string controlName)
{
Page page = new
Page();
UserControl ctl =
(UserControl)page.LoadControl("~/controls/" +
controlName);
page.Controls.Add(ctl);
StringWriter writer = new
StringWriter();
HttpContext.Current.Server.Execute(page, writer,
false);
return writer.ToString();
}

}



Notice that the bold text is the parameter name and it have to be same. It is recommended to be string
