    Set the AutoPostBack property to true.
    By default AutoPostBack property of CheckBox control is false, so the event related to checkbox will not work. You have to Set the AutoPostBack property to true. It enables you to post the web form back to the server automatically when the CheckBox is checked .
    Example:
    < asp:CheckBox ID="CheckBox1" runat="server" oncheckedchanged="CheckBox1_CheckedChanged" AutoPostBack="true"
    />
