checkchanged event not firing on uncheck

[jainmohit321]

i have set autopostback to true and viewstate to false.on checking the checkbox, page is getting reload and checkchanged is getting executed as normal. However on unchecking, only page is getting reload and checkchanged is not called.

I am using Microsoft visual studio 2008.

Hey jainmohit321, Check your code with the following code.

using System;
 
namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                Label1.Text = String.Empty;
                CheckBox1.AutoPostBack = true;
            }
        }
 
        protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
        {
            if (CheckBox1.Checked)
            {
                Label1.Text = "Checked";
            }
            else
            {
                Label1.Text = "Unchecked";
            }   
        }
    }
}
