Predmet:DataGridView - masked field text to time
Kako da u DataGridView postavim mask da upišem recimo 1111 ili 11,11 ili 11.11 i da mi to pretvori u vreme 11:11?
Stavio sam da mi je polje time (t) i ako upišem 11:11 radi ok ali hteo bih da olakšam unos da izbegnem : (shift + .)

Predmet:Re: DataGridView - masked field text to time
Ovo radi Smiling

sada imam sledeći problem. kada uklonim

Dim mtbc = New MaskedEditColumn
mtbc.Mask = "00/00/0000"
EquipmilesDataGridView.Columns.Add(mtbc)

iz load i u datagridu promenim ColumnType na MaskedEditColumn otvori mi dodatne opcije ali ne prihvata Mask.

Predmet:Re: DataGridView - masked field text to time
Kada dodam ovaj kod radi. Doda novo polje i prihvata mask:
Dim mtbc = New MaskedEditColumn
mtbc.Mask = "00:00"

CustomDataGridView1.Columns.Add(mtbc)
CustomDataGridView1.Columns(14).Name = "Test"
CustomDataGridView1.Columns(14).HeaderText = "TEST"

Ali kada hoću da promenim u DataGrid-u (CustomDataGridView1.Columns(13))kao na slici, mask ne radi na polju.

Da, aplikacija je za kontrolu vozila i sadrži:
- vozač 1 - ime i prezime
- vozač 2 - ime i prezime (ako su bila 2 vozača)
- relacija - teren na kome je išlo vozilo
- početna KM (polazak)
- završna KM (povratak)
- gorivo - natočeno litara
- vreme polaska - (polazak)
- vreme povratka - (povratak)

Ima viÅ¡e vozača, terena i naravno vozila u toku dana. Imam ovu aplikaciju u ms access-u i radi lepo i laka je koriÅ¡ćenje. Manje viÅ¡e sve radi na enter, minimalno koriÅ¡ćenje miÅ¡a (klik ili dva). Ako bih stavio unos u formi a pregled u DataGrid-u bilo bi nepregledno (malo). Gore unosiÅ¡ dole kontroliÅ¡eÅ¡. Možda ima neko bolje reÅ¡enje ali je ovako jednostavnije. Možda smo navikli tako da radimo pa zbog toga. U svakom slučaju držimo se ovakvog načina unosa. Ova trenutna aplikacija radi super (viÅ¡e korisnika, LAN) jedino Å¡to nam je problem (za lakÅ¡i i brži unos) su dve tačke ":" kada treba da se unese vreme. Ali i to je reÅ¡ivo kao Å¡to si poslao kod. Samo da nađem načina da ga povežem sa poljem.

U svakom slučaju, joÅ¡ jednom, hvala ti na pomoći i vremenu. Puno si mi pomogao
... a i devojkama koje unose ove podatke Smiling
