Thanks,
Hi! This is a common request in Power Apps — here's how to handle it.
The classic DatePicker control doesn't natively support "no value selected." The standard workaround is to use a Reset pattern with a toggle variable:
OnSelect
Set(varResetDate, true); Set(varResetDate, false)
varResetDate
Set(varDateSelected, false)
Set(varDateSelected, true)
OnChange
If you're using modern controls, the modern DatePicker supports a null/blank state natively. You can use Reset(DatePicker1) to clear it, or set the DefaultDate to Blank() so it starts empty.
Reset(DatePicker1)
DefaultDate
Blank()
Use IsBlank(DatePicker1.SelectedDate) to check whether a date has been selected before submitting a form.
IsBlank(DatePicker1.SelectedDate)
