** Backgound * In my UI is have a checkbox that enables or disables field. When the checkbox is set to false a few input fields are het to either false, null or "". The datePicker is one of them.

When the checkbox is set to false in the TS file I set the Date Picker value to null, like what happens when clicking the clear field in the UI of the datePicker.

The value of the field is indeed set to null (like via the UI) but the datePicker on the screen is not updated accordingly to the new value, to explain better when NULL the placeholder show be displayed. Setting any other date works fine, but I would like it the datepicker to work properly including the placeholder.

Expected behavior

this.form.controls.maxdate.setValue(null);

will show the placeholder on the screen:

[placeholder]="'Select max date'"

Actual behavior The previous value is still shown.
