Here Is my code

Please execute it.

Aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm52.aspx.cs" Inherits="WebApplication14.WebForm52" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
             <asp:ScriptManager ID="Script1" runat="server"></asp:ScriptManager>
            <h3>Dynamic Populate</h3>

    <asp:Button ID="Button5" runat="server" Text="Get Date" BackColor="Black" ForeColor="#FFCC00" Width="140px" Height="35px" /><br /><br />
    <asp:Label ID="Label2" runat="server" ></asp:Label>
    <ajaxToolkit:DynamicPopulateExtender ID="Label2_DynamicPopulateExtender" runat="server" PopulateTriggerControlID="Button5" ClientIDMode="Static" TargetControlID="Label2" ServiceMethod="GetData" />

            {

            }
        }

        [System.Web.Script.Services.ScriptMethod()]
        [System.Web.Services.WebMethod]
        public static String GetData()

Hi sanam13,

sanam13
I am executing the dynamic populate control but in output it does not work. I want to get date on button click but its not working.

sanam13

<asp:Button ID="Button5" runat="server" Text="Get Date" BackColor="Black" ForeColor="#FFCC00" Width="140px" Height="35px" /><br /><br />

This is caused by the postback after the Button is clicked. You can try to use the input button.

 <asp:ScriptManager ID="Script1" runat="server"></asp:ScriptManager>
            <h3>Dynamic Populate</h3>         
            <input id="Button5" type="button" value="Get Date" /><br /><br />
            <asp:Label ID="Label2" runat="server"></asp:Label>
            <ajaxToolkit:DynamicPopulateExtender ID="Label2_DynamicPopulateExtender" runat="server" PopulateTriggerControlID="Button5" ClientIDMode="Static" TargetControlID="Label2" ServiceMethod="GetData" />

The result:

Best regards,

Sam

Hi sanam13,

sanam13

public static String GetData()
        {
            return "Today is " + DateTime.Now.ToLongDateString();
        }

I tested your code and it works normally on my side.

Please set a breakpoint to debug your code, when you click the button, check whether GetData() is triggered.

Best regards,

Sam
