.cs site

ChkCapacity.Attributes.Add("OnClick", "EnableDisableControl(this,'" & ChkCapacity.ClientID & "','" & DDLCapacityKgs.ClientID & "')")

C#

function EnableDisableControl(source, Chk, ddl) {
    if (source.checked == false) {
        document.getElementById(ddl).selectedIndex = 0;
        document.getElementById(source.id.replace(Chk, ddl)).disabled = !source.checked;
    }
    else {
        document.getElementById(source.id.replace(Chk, ddl)).disabled = !source.checked;
        document.getElementById(ddl).focus();
    }
}
