Hi there! 👋
Great question — you've actually run right into a documented behavior change introduced by the updated Modern Date Picker control. Here's what's happening and how to fix it.
🔍 What Changed in the Updated Control
The updated version of the Modern Date Picker introduced a new DefaultDate property (this didn't exist in the previous version). This is key — because reset behavior in Power Apps is directly tied to the Default property of a control.
According to the Reset function – Microsoft Learn:
"The Reset function resets a control to its Default property value. Any user changes are discarded."
In the updated control, the equivalent of that "default value" is now the DefaultDate property. If DefaultDate is not explicitly set (or is set to a non-blank value), the control will not return to blank on reset — it will return to whatever DefaultDate resolves to.
✅ Fix: Set DefaultDate to Blank()
To restore the previous "reset to blank" behavior, explicitly set the DefaultDate property on your Modern Date Picker:
DefaultDate = Blank()
This tells the control that its default state is empty, so when Reset() or ResetForm() fires, it returns to blank as expected.
🛠️ If You're Inside an Edit Form
If the Date Picker sits inside an Edit Form control, note that Reset() cannot directly target controls inside a Gallery or Edit Form from outside — you must use ResetForm(FormName) on the form itself. Per Reset function – Microsoft Learn:
"You cannot reset controls that are within a Gallery or Edit form control from outside those controls."
Make sure your reset action is calling ResetForm() on the parent form, not Reset() on the date picker directly, when it's inside a form.
📋 Other Updated Control Changes to Be Aware Of
The update also renamed several properties (e.g., FontColor → Color, BorderRadius → RadiusTopLeft/TopRight/BottomLeft/BottomRight). If any of your formulas reference old property names, they may also need updating.
