Range selection in Angular Daterangepicker component

27 Apr 20246 minutes to read

Range selection in a DateRangePicker can be made-to-order with desire restrictions based on application needs.

Restrict the range within a range

You can restrict the minimum and maximum date that can be allowed as start date, end date in a range selection with help of min, max properties.

• min – sets the minimum date that can be selected as startDate.
• max – sets the maximum date that can be selected as endDate

In below sample, you can select a range from 15th day of this month to 15th day of next month.

app.component.ts

import { NgModule } from '@angular/core'
import { FormsModule } from '@angular/forms'
import { BrowserModule } from '@angular/platform-browser'
import { DateRangePickerModule } from '@syncfusion/ej2-angular-calendars'




import { Component } from '@angular/core';

@Component({
imports: [
        
        FormsModule,
        DateRangePickerModule
    ],


standalone: true,
    selector: 'app-root',
    styleUrls: ['./index.css'],
    template: `<ejs-daterangepicker [min]='minDate' [max]='maxDate' placeholder='Select a range'></ejs-daterangepicker>`
})
export class AppComponent {
    public today: Date = new Date();
    public currentYear: number = this.today.getFullYear();
    public currentMonth: number = this.today.getMonth();
    public currentDay: number = this.today.getDate();
    public minDate: Object = new Date(this.currentYear, this.currentMonth, 15);
    public maxDate: Object =  new Date(this.currentYear, this.currentMonth+1, 15);
     constructor() {
    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

 If the value of min or max properties changed through code behind, then you have to update the start date, end date property to set within the range. Or else , if the start and end date is out of specified date range, a validation error class will be appended to the input element. If strictMode is enabled, and both the start, end date is lesser than the min date then start and end date will be updated with min date. If both the start and end date is higher than the max date then start and end date will be updated with max date. Or else, if startDate is less than min date, startDate will be updated with min date or if endDate is greater than max date, endDate will be updated with the max date.

Range span

Span between ranges can be limited in order to avoid excess or less days selection towards the required days in a range.
In this, minimum and maximum span that can be allowed within the date range can be customized by minDays, maxDays properties.

• minDays- Sets the minimum number of days between start date and end date.
• maxDays- Sets the maximum number of days between start date and end date.
  In below sample, the range selection should be greater than 3 days and less than 8 days else it won’t set.

app.component.ts

import { NgModule } from '@angular/core'
import { FormsModule } from '@angular/forms'
import { BrowserModule } from '@angular/platform-browser'
import { DateRangePickerModule } from '@syncfusion/ej2-angular-calendars'




import { Component } from '@angular/core';

@Component({
imports: [
        
        FormsModule,
        DateRangePickerModule
    ],


standalone: true,
    selector: 'app-root',
    styleUrls: ['./index.css'],
    template: `<ejs-daterangepicker [minDays]='minDays' [maxDays]='maxDays' placeholder='Select a range'></ejs-daterangepicker>`
})
export class AppComponent {
    public minDays: Number = 4;
    public maxDays: Number = 7;
     constructor() {
    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Strict mode

DateRangePicker provides the option to limit the user towards entering the valid date only.
With strict mode, you can set only valid selection. Also, If any invalid range is specified then the date range value will reset to previous value.
This restriction can be availed by enabling the strictMode property.

    selector: 'app-root',
    styleUrls: ['./index.css'],
    template: `<ejs-daterangepicker strictMode='true' placeholder='Select a range'></ejs-daterangepicker>`
})

    constructor() {
    }
}
