I want 2 conditions using bind:

1. toDate should not be less than fromdate


2. to date should not be more than (fromdate+ 1 year) i.e maxvalue = fromdate+1 year

This is the code:

        var me = this;

        return [ {

            xtype : 'form',

            layout : 'hbox',

            border : false,

            items : [ {

                xtype : 'datefield',

                name : 'fromDate',

//              allowBlank : false,

                width : 110,

                fieldLabel : 'From',

                labelAlign : 'top',

                emptyText : 'mm/dd/yyyy',

                submitEmptyText : false,

                invalidText : '{0} is not a valid date!',

                fieldStyle : "font: bold 12px sans-serif;background:#fff;color:#444;",

                padding : 5,

                validator: function(value) {

                    if(value){

                        if(new Date(value) > new Date){

                            return 'From date must be less than current date.';

                        }else

                            return true;

                    } else {

                        return 'From date is required.';

                    }

                    var isRequired = me.oneFieldRequired();

                    if(typeof isRequired === "string")

                        return isRequired;

                    return me.validateName(value);

                }

            }, {

                xtype : 'datefield',

                name : 'toDate',

                width : 110,

                fieldLabel : 'To',

                labelAlign : 'top',

                emptyText : 'mm/dd/yyyy',

                invalidText : '{0} is not a valid date!',

                fieldStyle : "font: bold 12px sans-serif;background:#fff;color:#444;",

                padding : 5

            }, {

                xtype : 'button',

                padding : '4 8',

                margin : '30 0 0 3',

                text : 'Go',

                handler : function(btn) {

                    var thisForm = btn.up('form').getForm();

                    var formValues = thisForm.getValues();

                    if(!thisForm.findField("fromDate").validate())

                        return;



                    var toDate = formValues.toDate ? new Date(formValues.toDate) : new Date(),

                        t = toDate.getTime() - new Date(formValues.fromDate).getTime(),

                        cm = 24 * 60 * 60 * 1000 * 30,

                        monthRange = Math.floor(t / cm);

                    if(monthRange >= 0){

                        var ToDate = toDate;

                        if(monthRange > 11){

                            var fd = new Date(formValues.fromDate);

                            fd.setMonth(fd.getMonth()+11);

                            ToDate = new Date(fd.getFullYear(),fd.getMonth() + 1, 0);

                        }

                        ToDate = (ToDate.getMonth() + 1) + "/" + ToDate.getDate() + "/" + ToDate.getFullYear();

                        Ext.StoreManager.lookup('Visits').eAjax({

                            empiRefId : PatientManager.getPatientId(),

                            fromDate : formValues.fromDate,

                            toDate : ToDate,

                            preference : {

                                enableVisitTypeFilter : true,

                                outputType : 'highLevel'

                            }

                        }, this, {

                            success : function(records) {

                                me.showCustomView(records, formValues.fromDate, ToDate);

                            },
