How can I enable a radiobuttonlist only when a checkbox is checked?

I've tried with this code:

C#

if(cbCheck.Checked == true)
{
rblList.Enabled = true;
}
else
{
rblList.Enabled = false;
}

But, enabled state is not changing as checkbox cheked.

MAKE SURE IN ASPX page :
AutoPostBack="True" for your checkbox

Eg.

ASP.NET

<asp:checkbox id="cbCheck" runat="server" xmlns:asp="#unknown">
           oncheckedchanged="cbCheck_CheckedChanged" AutoPostBack="True" ></asp:checkbox>

C#

protected void cbCheck_CheckedChanged(object sender, EventArgs e)
    {
        if (cbCheck.Checked == true)
        {
            rblList.Enabled = true;
        }
        else
        {
            rblList.Enabled = false;
        }

    }

can u just try this in a new web page ,
<asp:CheckBox ID="cbCheck" runat="server"
oncheckedchanged="cbCheck_CheckedChanged" AutoPostBack="True" />
<asp:RadioButtonList ID="rblList" runat="server" Enabled="false">
<asp:ListItem>Item 1
<asp:ListItem>Item 2
<asp:ListItem>Item 3
<asp:ListItem>Item 4
<asp:ListItem>Item 5
<asp:ListItem>Item 6

And in code behind
protected void cbCheck_CheckedChanged(object sender, EventArgs e)
{
if (cbCheck.Checked == true)
{
rblList.Enabled = true;
}
else
{
rblList.Enabled = false;
}

}

I've set the 'AutoPostback' property of checkbox as 'true' and got the correct output.
thanks for all.
