Kryssruteformat och mallar

I det här avsnittet beskrivs format och mallar för CheckBox-kontrollelementet. Du kan ändra standard ControlTemplate för att ge kontrollen ett unikt utseende. Mer information finns i Skapa en mall för en kontroll.

Kryssrutekomponenter

Kontrollen CheckBox har inga namngivna delar.

Kryssrutan tillstånd

I följande tabell visas de visuella tillstånden för CheckBox-kontrollen.

VisualState-namn VisualStateGroup-namn Beskrivning
Normalt Gemensamma Stater Standardtillståndet.
håll muspekaren över Gemensamma Stater Muspekaren är placerad över kontrollen.
Tryckt Gemensamma Stater Kontrollknappen trycks in.
Handikappad Gemensamma Stater Kontrollen är inaktiverad.
Fokuserad FocusStates Kontrollen har fokus.
Ofokuserad FocusStates Kontrollen saknar fokus.
Kontrollerad CheckStates IsChecked är true.
Okontrollerat CheckStates IsChecked är false.
Obestämt CheckStates IsThreeState är trueoch IsChecked är null.
Giltig Valideringstillstånd Kontrollen använder Validation-klassen och den bifogade egenskapen Validation.HasError är false.
OgiltigOavfokuserad Valideringstillstånd Den bifogade egenskapen Validation.HasError är true när kontrollen har fokus.
OgiltigtFokuserat Valideringstillstånd Den Validation.HasError kopplade egenskapen true visar att kontrollen inte har fokus.
