How to use B4XTable and searchfield ( search by date ) ?
Date Value are saved as ticks, (1652824800000 = 05/18/2022 ) ... search using MM/dd/yyyy or 1652824800000 ticks not working.
Any suggestion?
I have just checked at www.unixtimestamp.com
given tick value shows current saved item with yesterday's datum
B4X:
Format Milliseconds (1/1,000 second)
GMT Tue May 17 2022 22:00:00 GMT+0000

after setupping like that.... i give it's value (parsing) like "ticks"...
A solution that already do at mine b4xtables... is an extra search textfield... that searching direct the db... So is using ticks for showing into b4xtable... but when I want to search something I search db-table and show only specific rows... (but this only an idea - may be not works for you)
For input data in table I use preferences dialog and there is problem because ...
If I add new record to table using preferences dialog and Table Column ( B4XTable.COLUMN_TYPE_DATE ) it shows
wrong tick value so this option will not work ( unless I input time ticks like item.Put("key", date_string ... )
ticks value is 18h old at the moment you save it ( see 1st post ) at least that's what I see on my PC
( maybe problem is in preferences dialog and some date format or how it set ticks, don't know and for now also less important )
will save it as txt string so search option will work for date also.
Private Sub ShowDialog(Item As Map, RowId As Long)
...
Dim date_string As String
DateTime.DateFormat = "MM/dd/yyyy"
date_string=DateTime.Date(DateTime.Now)
params.AddAll(Array(Item.Get("Model"), Item.Get("Name"), Item.Get("Datum"), .... 'remove'
params.AddAll(Array(Item.Get("Model"), Item.Get("Name"), date_string,.... 'add'
' or item.Put("Datum",date_string)'
...If you passed the values/parameters into b4xtable (with column b4xtable1.COLUMN_TYPE_DATE)...
i don't think you ll have problem at showing... using DateTime.DateParse(stringitemyoutakefromanywhere)
but for search as you said.. you must think the way different... may be you can have a column hidden (width:1) with string date too.. (another solution if you don't want an extra textfield for search)
at preferences dialog if using Date Field (Erel's Form Builder json) you set it with ticks for example: (options.put("keyname",datetime.now)
At this point with preferences dialog and date picker ( options.put("keyname",datetime.now) is also not an option, what if user select 'daytime.now <> 2 days ... Ticks value will be saved with time you have entered New values...
