Using IsBlank in formula for Date Time Picker field on Power Apps

Question

Pretty new to SharePoint and Power Apps so would like to ask if what I am trying to do is feasible.

I have a Date Time Picker field in my formula in Power Apps and currently, its default value is set to: Now()

I would like to know if it is possible to check first if the value for that column in the list item is empty or not.

Answer 1

You can check for blank values in Power Apps using IsBlank() or IsBlankOrError() functions.

For example:

Check if selected date in date picker control in Power Apps is blank or not:

IsBlank(DatePicker1.SelectedDate)

OR

IsBlankOrError(DatePicker1.SelectedDate)

Check if date column value in current SharePoint form context is blank or not:

IsBlank(ThisItem.NameOfDateColumn)

OR

IsBlankOrError(ThisItem.NameOfDateColumn)

Where NameOfDateColumn is the name of your date & time column in SharePoint list.
