I have a form with SharePoint as the datasource. When i select a past date (i.e date less than today) from date picker and click on Save, powerapp doesn't allow to save me the record and displays validation error correctly, however the selected date gets reset after clicking on save.

May i know how to avoid this ?

My favorite way is to disable the Submit button until the user has input valid information in the form.

Put this code in the DisplayMode property of the Submit button

If(DataCardValue3.SelectedDate < MyDate, DisplayMode.Disabled, DisplayMode.Edit)

Then, to alert the user when an invalid date value was entered, put this code in the OnChange property of the DatePicker.

If(DataCardValue3.SelectedDate < MyDate, Notify("You cannot enter a past date", NotificationType.Error))

Finally, put this code in the OnSuccess property of the form to show that the record was successfully submitted

Notify("This record has been saved successfully", NotificationType.Success)

Hi @Iantaylor2050 ,

Do you mean that your datepicker will reset automatically if it does not submit the form when clicking the save button?

I've made a similar test but not met the same problem as your description.

I suggest you refer this to check where's your problem:

1)the form's settings:
DefaultMode: FormMode.New

2)datepicker's settings:

InputTextPlaceholder: blank (set nothing)

IsEditable: true

DefaultDate: Parent.Default

3)the submit button's OnSelect:

If(DataCardValue5.SelectedDate<Today(),Notify("wrong date",NotificationType.Error),SubmitForm(Form1);Notify("right",NotificationType.Success))

(this submit button is outside the form)

If I choose date before today, it will return error and not reset the datepicker.

Best regards,
