Empty Value for date

[_kikilalaaa]

Hi All. 

I am trying to make a form to check whether the food has expired. In the form there are 2 datacard: "Has Expired" and "Expiry Date". 

The "Expiry Date" datacard will be only visible if user select "Yes" for "Has Expired" datacard. This form will be submitted and the data will be stored in sharepoint list. Then, user can view the form that they have submit.

The problem I am facing is that when the user select "No", the sharepoint list still update the default date. How to make it empty?

1. I have tried to clear the date inputtextholder properties. However, this also cleared the date enter by user when they select "Yes", when they view the form.

p/s: I am still new in PowerApps. Hope the experts can help me.

Hi,

A few questions:

1. What are you using to submit the form? SubmitForm or Patch?

2. What is the default property of the expiry date card?

I would suggest using this code in the Update property of your DataCard for ExpiryDate.  When the Has Expired toggle shows "Yes" the selected expiry date will be updated in Sharepoint and when "No" the expired date will be updated as a blank field.

If(
    toggle_HasExpired.Value=True,
    DataCardValue_ExpiryDate.SelectedDate,
    Blank()
);

Another tip: it would be a good idea only to show the Expiry Date datepicker when Has Expired is True.  To do that put this code in the Visible property of the Expiry Date datacard.

toggle_HasExpired.Value

Hi, to answer your question:

1. I use SubmitForm
2. The default = ThisItem.ExpiryDate

Hi, I have tried this method but it still show the present date. I think maube I need to change the default but I don't know what to replace it with.

You can try 2 things:

1. Add the if condition in the default property of the date card to only have a default if the has expired is set to yes, OR

2. If you can use Patch instead of SubmitForm, you can control what values you want to update when directly in your formula.

Let me know if either works.

Hiii all!

I have figured it out. Apparently my mistake was I set the Date data type in the Sharepoint as date and time.

How I fix it:

1. Set the data type for date in Sharepoint as single line text
2. Add Datepicker in Date datacard in PowerApps. So now, you supposed to have 2 fields in the same datacard; datepicker and textfield.
3. Textfield:Default = Blank()
4. Date DataCard: Update = If(radio. Selected. Value ="Yes", DatePicker. SelectedDate, Textfield.Text)
5. Date DataCard:Visible = Radio. Selected. Value = "yes"

I struggled with the same issue.

You have to go into the column setting and select (None) as Default value.

None of these answers worked for me and I really did not want to recreate the date columns in separate text columns.

I had to use this formula on the submit button:

SubmitForm(Form1); If(Or(IsBlankOrError(DataCardValue8.SelectedDate), IsBlankOrError(DataCardValue9.SelectedDate)), RecordsRetentionSetNullDates.Run(RecordsRetentionList.Selected.ID, IsBlank(DataCardValue8.SelectedDate), IsBlank(DataCardValue9.SelectedDate)), "");

And set up a corresponding flow to input those null values in the date fields.
