Hello to all,

I'm using AnotherDatePicker class, and in my layout I have a DatePickerLabel and other objects.

If the customer has click on the DatePickerLabel, the DatePicker open and the customer can select a date.

But how can I disable it, so if the customer has click on DatePickerLabel the DatePicker don't open ??

In some situation I want to fix to a date, so I call
B4X: 
TheDate.SetDate(DateTime.now, True)
but I don't want that the customer can change it, so I need a
B4X: 
TheDate.Enabled = False

How can do it ??

Thanks
Sergio

Thanks Erel,
I have solved !!

I have only add this SUB to AnotherDatePicker class and all is perfect !!
B4X: 
Public Sub EnableDisable(Enabled As Boolean)
   If waitForAddToActivity Then
     CallSubDelayed2(Me, "EnableDisable", Enabled)
     Return
   End If
   targetLabel.Enabled = Enabled
End Sub

If you want, add this SUB also to your source and change version to 1.12
