In this article I am going to explain how we can call a
Server Side method from Java Script in asp.net c#.
Below
is my aspx code:
<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
%>
<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Java Script: Calling Server Side Method</title>
<script type="text/javascript"
language="javascript">
function jsCallServerSideMethod() {
var _msg = $get("txtMessage").value;
PageMethods.GetUserMessage(_msg, OnSuccess, OnFailure);
}
function OnSuccess(result) {
if
(result) {
alert(result);
}
}
function OnFailure(error) {
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1"
runat="server"
EnablePageMethods="True">
</asp:ScriptManager>
<table style="border: solid
15px blue; width: 100%; vertical-align: central;" cellpadding="10"
cellspacing="10">
<tr>
<td style="padding-left: 20px;
padding-top: 20px; padding-bottom: 20px; background-color: skyblue;
font-family: 'Times New Roman'; font-size: 20pt; color: red;">
Java Script: Calling Server Side Method
</td>
</tr>
<tr>
<td style="text-align: left;
font-family: Times New Roman; font-size: 12pt;">
Enter Your Message #
<asp:TextBox ID="txtMessage"
runat="server"
Width="200px"></asp:TextBox>
<asp:Button ID="btnClick"
runat="server"
Text="Click"
OnClientClick="jsCallServerSideMethod()"
/>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
Now
my aspx.cs code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
public partial class _Default :
System.Web.UI.Page
{
protected void
Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
public static string GetUserMessage(string
message)
{
return "Welcome
" + message + Environment.NewLine
+ System.DateTime.Now;
}
}
Now run the application:
