Disabling input elements in a form

Disabling input elements in a form

I am writing a ASP.NET UserControl and I am trying to incorporate JQuery into this.
The control is a simple form with a few input fields (text, checkbox, select, radio).
The first element in the form is a checkbox. Upon clicking this checkbox I want the all the input elements in the form (except the checkbox control itself) to be enable/disable. I tried writing some of this code but my solution was not getting me anywhere.
Below is the ASP.NET form code. I'd appreciate the help with some code or pointers into what I am doing wrong.
 
<
asp : Panel ID ="pnlInputControls" runat ="server">
 
 
< table style =" width :100%;">

<tr>

<td style="width:50%">

<asp:CheckBox ID="chkBenefitName" runat="server" Checked="true" TextAlign="Right" ClientIDMode="AutoID" style="padding:0 0 0 10" Text="Senior Citizen Homeowners' Exemption (SCHE)" />

</td>

 < td style =" width : 40%; text-align : left;">

< asp : DropDownList ID ="ddlPriorBenefits" runat ="server" style =" width :45%;" ClientIDMode ="AutoID">

< asp : ListItem Text ="August 12, 2010" Value ="1" />

</ asp : DropDownList >

</ td >

< td style =" width : 10%; text-align : left;">< asp : Button ID ="btnNewBenefitPeriod" ClientIDMode ="AutoID" runat ="server" Text ="New" /></ td >

</ tr >

< tr >

< td style =" width :50%; vertical-align :top; text-align :left;">

< asp : DropDownList ID ="ddlSpecialProgram" runat ="server" ClientIDMode ="AutoID" style =" width : 80%;">

< asp : ListItem Text ="Program 1" Value ="1" />

< asp : ListItem Text ="Program 2" Value ="2" />

</ asp : DropDownList >

</ td >

< td style =" width :50%; vertical-align :top; text-align :left;" colspan ="2">

< table style =" width :100%;">

< tr >

< td style =" width :50%;"> # Household Members </ td >

< td >< asp : TextBox ID ="txtHouseholdMembersCount" runat ="server" ClientIDMode ="AutoID"></ asp : TextBox ></ td >

</ tr >

< tr >

< td style =" width :50%;"> Amount </ td >

< td >< asp : TextBox ID ="txtAmount" runat ="server" ClientIDMode ="AutoID" ></ asp : TextBox ></ td >

</ tr >

</table>

</td>

</tr>

</table>

 </ asp : Panel >
 
 
I'd appreciate the help.
