Hello,

there seems to be a problem with library dialogs version 3.00 and B4A version 6.80

As instructed, i replaced library dialogs version 2.92 with library dialogs version 3.00 when upgrading to B4A version 6.80.

However, it seems to be that the method "ShowCalendar" is no longer supported.

Dim dialog As DateDialog
dialog.ShowCalendar= True

Please advise on how to solve the problem

You have to delete .ShowCalendar and re-select.

B4X: 
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
  
    dia.ShowCalender = True
  
End Sub

Sub Activity_Resume
    dia.Show("Test","Title","OK","Cancel","Negative",Null)
  
End Sub
works for me

Hello,
I use Filedialog to let the user saving a text file somewhere on his phone.
The app propose a default filename trough .ChosenName property but once the user changes the directory the filename disappears from the upper EditText.
Is there a way to avoid that? or to add a separate .DefaultName property?

Tks
