| Handikappad | Gemensamma Stater | DatePicker är inaktiverad. |
| Giltig | Valideringstillstånd | Kontrollen använder Validation-klassen och den bifogade egenskapen Validation.HasError är false. |
| OgiltigtFokuserat | Valideringstillstånd | Den bifogade egenskapen Validation.HasError är true när kontrollen har fokus. |
| OgiltigOavfokuserad | Valideringstillstånd | Den Validation.HasError kopplade egenskapen true visar att kontrollen inte har fokus. |
Delar av DatePickerTextBox
I följande tabell visas de namngivna delarna för DatePickerTextBox-kontrollen.
| Del | Typ | Beskrivning |
|---|---|---|
| PART_Vattenmärke | ContentControl | Elementet som innehåller den inledande texten i DatePicker. |
| PART_ContentElement | FrameworkElement | Ett visuellt element som kan innehålla en FrameworkElement. Texten i TextBox visas i det här elementet. |
DatePickerTextBox-tillstånd
I följande tabell visas de visuella tillstånden för DatePickerTextBox-kontrollen.
| VisualState-namn | VisualStateGroup-namn | Beskrivning |
|---|---|---|
| Normalt | Gemensamma Stater | Standardtillståndet. |
| Handikappad | Gemensamma Stater | DatePickerTextBox är inaktiverad. |
| håll muspekaren över | Gemensamma Stater | Muspekaren placeras över DatePickerTextBox. |
| ReadOnly | Gemensamma Stater | Användaren kan inte ändra texten i DatePickerTextBox. |
| Fokuserad | FocusStates | Kontrollen har fokus. |
| Ofokuserad | FocusStates | Kontrollen saknar fokus. |
| Vattenstämpel | WatermarkStates | Kontrollen visar sin ursprungliga text. DatePickerTextBox är i tillståndet när användaren inte har angett text eller valt ett datum. |
| Utan vattenmärke | VattenmärkesStatusar | Användaren har angett text i DatePickerTextBox eller valt ett datum i DatePicker. |
| Giltig | Valideringstillstånd | Kontrollen använder Validation-klassen och den bifogade egenskapen Validation.HasError är false. |
| OgiltigtFokuserat | Valideringstillstånd | Den Validation.HasError bundna egenskapen är true och kontrollen har fokus. |
| OgiltigOavfokuserad | Valideringstillstånd | Den kopplade egenskapen Validation.HasError är true och kontrollelementet har inte fokus. |
DatePicker ControlTemplate-exempel
I följande exempel visas hur du definierar en ControlTemplate för DatePicker-kontrollen.

in the application. DatePickerCalendarStyle is based on the implicit
style so that the DatePicker will use the application's calendar style.-->
