Welcome again, here is one more trick to enable or disable the multiple textboxes based on the check box event.

Please write the following code in Script area of the page.

<script type="text/javascript">
    function enableDisable(bEnable, textBoxID, textBoxID2)
         document.getElementById(textBoxID).disabled = !bEnable
         document.getElementById(textBoxID2).disabled = !bEnable

Put the controls as shown below in the Form area...

<asp:TextBox ID="t1" Text="" runat="server" />
 <asp:TextBox ID="t2" Text="" runat="server" />
 <asp:CheckBox ID="chk1" Checked="true" onclick="enableDisable(this.checked, 't1','t2');" runat="server" />

and let it behave as it's done....

Browse the page and check that out!

Reason for my vote of 5
Good solution - better and more readable than the rest. Have you considered updating to include a jQuery solution?
