var btnNextp = Ext.getCmp('<% = btnNextPage.ClientID %>').getEl().dom.id;
//var  btnNextp = document.getElementById('<% = btnNextPage.ClientID %>');

// $("#btnNextPage").attr({ disabled: "false" }); 
Ext.getCmp('btnNextp').setBtnDisable(false); //not works properly
// Ext.getCmp('btnNextPage').enable();   //not works properly

These examples also creates uncaught errors in javascript.But why ?where is the problems. Thanks in advance.

Try this:

<script type="text/javascript">

    var EnableButton = function () {
        var btnNextp = #{btnNextPage};
            btnNextp.setDisabled(false);
    };

</script>
