Hi @Eben98,
1. The OnChange property of the date picker control will help to achieve your goal , use there the Reset(DatePicker1) function into a If clause. Something like this:
If(DatePicker1.SelectedDate>DateAdd(Today(),3,Months), Reset(DatePicker1))
Also, for usability, you can:
- put an error label to explain to users why the datepicker control was reseted. And Set the visible property of this label to be true when the selected date does not meet your condition.
- set the Display Mode property of the submit button to Disabled when the selected date does not meet your condition.
2. Set the Default property of date picker control to Today().
