You can filter your data source and see if it returns anything. If it is blank then there is not any overlap. In this example DataSource is your database, StartDate and EndDate are the respective column names in your database.

If(
  !IsBlank(
    Filter(
      DataSource,
      (StartDate >= StartDatePicker.SelectedDate && StartDate <= EndDatePicker.SelectedDate) || (EndDate >= StartDatePicker.SelectedDate && EndDate <= EndDatePicker.SelectedDate)
    )
  ),
  Notify("Date already selected", NotificationType.Error)
)

@JD382

Thank you

Hi @JD382 

your solution is working but i have another problem

 

if i am taking request from 1st to 5th and try to take a request on 3rd then am i am able to take request.

 

but in my case a dont want to allow user to take request between date

 

thanks in advance

You can add another criterion to the filter function.

 

|| (startdate <= StartDatePicker.SelectedDate && enddate >= EndDatePicker.SelectedDate)

 

This captures any existing requests that completely encompass the start and end dates that the user picks.

Hi @JD382 

i have taken a leave on 21st to 23rd

 

and trying to take a leave on 21st, then its allow to take a leave, but i dont want to allow 21st date to take a leave
