Error in SelectedDate property of DatePicker Canvas within a Gallery

Posted on by BL-19121342-0

I'm trying to create a component that uses a gallery, and one of its items contains a Modern DatePicker Canvas.

This control is producing an inexplicable error.

I placed this code in the SelectedDate property of the control (note that the code returns the date 11/2/2026, 12:00:00).

When I select a date later than the date in the SelectedDate property of the right Modern DatePicker Canvas in the left Modern DatePicker Canvas, the date in the SelectedDate property of the right Modern DatePicker Canvas is blanked (note that the code returns "En blanco"), but the right Modern DatePicker Canvas continues to behave as if it has the initial date set in its SelectedDate property (i.e., 11/2/2026, 12:00:00).

I've reset the Modern DatePicker Canvas on the right after trying to clear the date in its SelectedDate property in multiple ways to reflect the new value (I even set 'Reset(dtePckFilterItemUntil)' in its OnChange property, which caused the control to reset to its initial date - 11/2/2026, 12:00:00 - every time I select a new date, it doesn't clear).

Has anyone else experienced this?

Does anyone know how to solve this problem?

I hope someone can provide a solution.

Hello @BL-19121342-0

Try setting the logic on DefaultDate and explicitly returning Blank when the date isn’t found. For example:

Default Date:

With( { d: LookUp( LookUp(colFilterItems; ID = 5).Items; ID = Last(LookUp(colFilterItems; ID = 5).DefaultItemsIDs).Value ).Value }; If( IsBlank(d); Blank(); DateValue(d) ) ) //Please update the collection name and column name if it's wrong.

if the lookup doesn’t find a date, it will be empty.

Hi @BL-19121342-0,

There are two issues here - firstly, I believe this is a Modern Date Picker bug - they do not reset properly. To establish whether this is the case with you, use a Classic Date Picker and see if that works.

The second issue is that controls inside a Component do not have direct access to data sources - you may have worked around this, but the easiest way to test is put the same objects in the app itself and see what works there.
