Behavior Settings

DatePicker has some default behavior settings which helps you to perform more operation by Built-in.

Selected Date

DatePicker value can be selected through picking date from DatePicker calendar or you can set it by using value property.

  • html
  • <div class="row">
        <div class="date-align">  
    	<div>
    		<label class="dtlabel">End Date</label>   
    		<input id="enddate" ej-datepicker [(value)]= "dtValue" (select)= "onSelectDate($event)" />
    	</div>
        </div>    
        </div>
  • html
  • import { Component } from '@angular/core';
    @Component({
      selector: 'ej-app',
      templateUrl: './date-range.component.html',
      styleUrls: ['./common.component.css']
    })
    export class DateRangeComponent {
      today: any;
      currentYear: number;
      currentMonth: number;
      currentDay: number;
      dtValue: any;
      constructor() {
          this.today = new Date();
          this.currentYear = this.today.getFullYear();
          this.currentMonth = this.today.getMonth();
          this.currentDay = this.today.getDate();
          this.dtValue = new Date(this.currentYear, this.currentMonth, this.currentDay + 7);
      }
      onSelectDate(args) {
          alert(" previous date is : " + args.prevDate + " \n selected date is : " + args.value);
      }
    }

    DatePicker allows only the valid date to be entered and it should be within the specified range. By default, strict mode is enabled in DatePicker, so it will restrict invalid date and resets to previous date if it’s not valid. To know more about strict mode refer Strict Mode.

    Date Range

    DatePicker provides an option to restrict the user to pick the date from specified range of value. You can utilize this option by make use of minDate and maxDate property.

    minDate - specifies the minimum date to be picked in DatePicker calendar by disabling below date of minDate.

    maxDate - specifies the maximum date to be picked in DatePicker calendar by disabling above date of maxDate.

    		<label class="dtlabel">Start Date</label>
    		<input id="stdate" ej-datepicker [(value)]= "startDateValue" [(minDate)]= "minStartDate" [(maxDate)]= "maxStartDate" [(width)]= "width" (select)= "onStartSelectDate($event)" />

          this.currentMonthStart = this.today.getMonth();
          this.currentDayStart = this.today.getDate();
          this.startDateValue = this.today;
          this.minStartDate = new Date(this.currentYearStart, this.currentMonthStart, this.currentDayStart - 7);
          this.maxStartDate = new Date(this.currentYearStart, this.currentMonthStart + 3, this.currentDayStart);
          this.endDateValue = new Date(this.currentYearStart, this.currentMonthStart, this.currentDayStart + 7);
          this.minEndDate = this.today;
          this.maxEndDate = new Date(this.currentYearStart, this.currentMonthStart + 3, this.currentDayStart);
      }
      onStartSelectDate(args) {
          let curDate = new Date(args.value);
          this.minEndDate =  curDate;
          this.endDateValue =  new Date(curDate.getFullYear(), curDate.getMonth(), curDate.getDate() + 7);
      }
      onEndSelectDate(args) {
          this.maxStartDate = args.value;
      }
    }

    NOTE

    You can change the ‘minDate’ and ‘maxDate’ value dynamically like ‘value’ property

    Display Inline Mode

    DatePicker provides an option to act as calendar by setting the displayInline property as true. In this mode the DatePicker calendar has been placed open state constantly to pick the date.

    You can make use of ‘div’ element to create DatePicker when you going for inline mode, which gives good visualization as like calendar in page instead of creating with ‘input’ element.

  • html
  • <div align="center">
        <div id="datepick" ej-datepicker [(ngModel)]="value" [(displayInline)]="inline"> </div> <br />
        <div id="label">Selected date: </div>
        </div>
  • html
  • import { Component } from '@angular/core';
    @Component({
      selector: 'ej-app',
      templateUrl: './display-inline.component.html'
    })
    export class DisplayInlineComponent {
      value: string;
      inline: boolean;
      constructor() {
        this.value = Date();
        this.inline = true;
      }
    }

    Strict Mode

    Strict mode in DatePicker allows you to enter valid or invalid date in input textbox, but an error class will get added to exhibit if it’s an invalid date. When you set enableStrictMode to false, DatePicker allows you to enter only the valid date or else it will resets with previous value.

    Also the valid date should be defined in specified range or else it resets to min or maximum date when the entered date is out of range

    By default “enableStrictMode” is true, so you can enter any value other than date too, but an error class (‘. e - error’) will get added to wrapper to highlight the invalid date.

  • html
  • <div align="center">
        <input type="text" id="datepick" ej-datepicker [(enableStrictMode)]="enable"/>
        </div>
        <style>
        /* error class to highlight invalid date */
        .e-error .e-input {
            color: Red; /* highlights invalid date font color in input */
        }
        </style>
  • html
  • import { Component } from '@angular/core';
    
    @Component({
      selector: 'ej-app',
      templateUrl: './rtl.component.html'
    })
    export class RTLComponent {
      enable: boolean;
      constructor() {
        this.enable = true;
      }
    }

    You can also override the error class to highlight when invalid date is entered.
