Hi Sir,
I am facing this error, i.e: Only Content controls are allowed directly in a content page that contains content controls.

Thanks.

You cannot have <head> and such tags in a page which uses CSS (they are already in the stylesheet). Cut your page down (this is a cut down sample from one of mine):

htm

<![CDATA[<%@ Page Language="C#" MasterPageFile="~/Resources/Masters/OverAll.master" AutoEventWireup="true"
    CodeFile="Default.aspx.cs" Inherits="_Default" %>
<![CDATA[<%@ MasterType VirtualPath="~/Resources/Masters/OverAll.master" %>
<asp:content id="ContentHead" contentplaceholderid="pageHead" runat="Server" xmlns:asp="#unknown">
    <!--  Empty - emergencies only, at top of page.  -->

<asp:content id="ContentBody" contentplaceholderid="cphBody" runat="Server" xmlns:asp="#unknown">
    <script type="text/javascript" language="javascript">
        function getSelectValue(sel) {
            var val;
            // only if there is a selected item
            if (sel.selectedIndex > -1) {
                // get the value from the select element
                val = sel.options[sel.selectedIndex].value;
                // alert(val);
            }
            return val;
        }

        function ddlChange(DropDownID, TextBoxID) {
            var c = document.getElementById(DropDownID);
            var div = document.getElementById(TextBoxID);
            if (getSelectValue(c) == '108') {
                div.value = '';
                div.style.visibility = "visible";
                if (div.Validators && div.Validators.length) {
                    for (var i = 0; i < div.Validators.length; i++)
                        ValidatorEnable(div.Validators[i], true)
                }
            }
            else {
                div.value = '108';
                div.style.visibility = "hidden";
                if (div.Validators && div.Validators.length) {
                    for (var i = 0; i < div.Validators.length; i++)
                        ValidatorEnable(div.Validators[i], false)
                }
            }
        }
 
    </script>
