I have a checkbox in my aspx page. Inside the checkbox i have a Div which lists some student name from Database. I have a condition to check if my there are no students to list in DB. I need to make the checkbox as ReadOnly or disabled.

  <tr>
    <td><label for="checkBoxSudent">                         <input type="checkbox" id="checkBoxSudent" />
Select Student Name</label>
    </td>
  </tr>
</table>

<div id="listStudent" style="display: none">
  <table id="addStudents" runat="server" style="margin-left: 15px; margin-top: 5px; margin-bottom: 5px" border-top="2">

    <tr>
      <td class="selectName">
        <asp:CheckBoxList ID="chkSelecStud" runat="server" CssClass="myCheckBoxList">
        </asp:CheckBoxList>
      </td>
    </tr>
  </table>
