If your page takes time to refresh and you want to disable the checkbox then

protected void chkbox1_CheckedChanged(object sender, EventArgs e)

{

chkbox1.Enabled = false;//check box disable

}

and if you want to enable after reload

protected void Page_Load(object sender, EventArgs e)

{

chkbox1.Enabled = true;//check box enable

}
