Can't bind to 'matDatepicker' since it isn't a known property of 'input' - Angular

Question

I have just copied and pasted angular material code for datePicker and input, but I am getting this error for the datePicker.

app.module

import {MaterialModule} from '@angular/material';
@NgModule({
imports: [
...
MaterialModule
]

<md-input-container>
    <input mdInput placeholder="Rechercher" [(ngModel)]="filterHistorique">
</md-input-container>

<md-input-container>
    <input mdInput [mdDatepicker]="picker" placeholder="Choose a date">
    <button mdSuffix [mdDatepickerToggle]="picker"></button>
</md-input-container>
<md-datepicker #picker></md-datepicker>

This is the error I am having in my browser:

Can't bind to 'mdDatepicker' since it isn't a known property of 'input' If 'md-datepicker' is an Angular component, then verify that it is part of this module. 2. If 'md-datepicker' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message. (" [ERROR ->]

The error is for the datepicker, when I removed it, the errors disappears

Solution 1

While using mat-datepicker, you have to import MatDatepickerModule as well, also MatNativeDateModule is recommended to be imported too. see docs here.

import { MaterialModule, MatDatepickerModule, MatNativeDateModule } from '@angular/material';
@NgModule({
  imports: [
    ...
    MaterialModule,            // <----- this module will be deprecated in the future version.
    MatDatepickerModule,        // <----- import(must)
    MatNativeDateModule,        // <----- import for date formating(optional)
    MatMomentDateModule         // <----- import for date formating adapted to more locales(optional)
  ]

For optional module of date formating, see Module for DateAdapter from material team.

Mention: please avoid using MaterialModule for it'll be deprecated in the future.

Solution 2

you need to import FormsModule and ReactiveFormsModule if you used NgModule and formgroup. so your app.module should be like that

import {MaterialModule} from '@angular/material';
@NgModule({
  imports: [
    MdDatepickerModule,        
    MdNativeDateModule,
    FormsModule,
    ReactiveFormsModule
  ]

Note: MaterialModule Removed. please use separate module instead. like MdDatepickerModule see here https://github.com/angular/material2/blob/master/CHANGELOG.md#200-beta11-carapace-parapet-2017-09-21

Solution 3

To use MatDatePicker in application add the following lines in your app.module.ts (or the current module your component/page belongs to) file:

1. import MatDatepickerModule, MatNativeDateModule in your app.module.ts.

import { MatDatepickerModule, MatNativeDateModule } from '@angular/material';

for angular 10.x import them independently

import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatNativeDateModule } from '@angular/material/core';

2. Add MatDatepickerModule, MatNativeDateModule under @NgModule in imports and exports' array:

@NgModule ({
           imports: [
               MatDatepickerModule,
               MatNativeDateModule 
           ],
           exports: [
               MatDatepickerModule, 
               MatNativeDateModule 
           ]
       })

Solution 4

You just need to import below module

import {MatDatepickerModule} from '@angular/material/datepicker';

@NgModule ({
  imports: [
    MatDatepickerModule
   ]
  })

Solution 5

Below import works for me my on my solution in Angular8

@NgModule ({
        imports: [
            MatDatepickerModule,
            MatNativeDateModule,
        ]
 });

I need to update my @angular/material module to the latest version for currently, my IDE doesn't find MdDatePickerModule when I import it. I guess, once it will be done, my problem will be solved

[Pengyy]

@edkeveked ok, maybe you will need to update all @angular/xxx packages as well based on the latest @angular/material(I have done this thing before). good luck.

[Nate Gardner]

This isn't working for me... Even though MdDatepickerModule is in the app.module, the error persists.

[Pengyy]

@NateGardner where are you using mdDatePicker? is this used at submodule?

[Robert Bernstein]

@Pengyy, this worked really well for me, thanks. FYI, I didn't need MaterialModule.

[Pengyy]

@RobertBernstein the MaterialModule will be deprecated in the future version, better to not use it any more. I have add some comments in my answer.

[crthompson]

MdDatePickerModule has been renamed to MatDatepickerModule

[Brian Schantz]

Also make sure you're adding [matDatepicker], not [matDatePicker]. Don't ask me how I know this.

[Nino Filiu]

Thanks @pengyy, importing this optional module also helps with this annoying no-error-logged mat-datepicker bug.

[khizer]

why to add in exports array ? @vaishali chaudhari is it when you have created a seperated module and you try to export all mat module from that shared module?
