Estilos e modelos ListView
Este tópico descreve os estilos e modelos para o ListView controle. Você pode modificar o padrão ControlTemplate para dar ao controle uma aparência exclusiva. Para obter mais informações, consulte Criar um modelo para um controle.
Peças ListView
O ListView controle não tem nenhuma parte nomeada.
Quando você cria um para um , seu modelo pode conter um dentro de um ControlTemplateItemsPresenterListViewScrollViewer. (O ItemsPresenter exibe cada item no ListView; o habilita a ScrollViewer rolagem dentro do controle). Se o não é o ItemsPresenter filho direto do ScrollViewer, você deve dar o ItemsPresenter nome, ItemsPresenter.
ListView Estados
A tabela a seguir lista os estados visuais do ListView controle.
| Nome do VisualState | Nome do VisualStateGroup | Descrição |
|---|---|---|
| Válido | ValidationStates | O controle usa a classe e a Validation propriedade anexada Validation.HasError é false. |
| InvalidFocused | ValidationStates | A Validation.HasError propriedade anexada é true tem o controle tem foco. |
| InvalidUnfocused | ValidationStates | A Validation.HasError propriedade anexada é true tem o controle não tem foco. |
Peças ListViewItem
O ListViewItem controle não tem nenhuma parte nomeada.
Estados ListViewItem
A tabela a seguir lista os estados para o ListViewItem controle.
| Nome do VisualState | Nome do VisualStateGroup | Descrição |
|---|---|---|
| Normal | CommonStates | O estado padrão. |
| Desabilitadas | CommonStates | O controle está desabilitado. |
| MouseOver | CommonStates | O ponteiro do mouse está sobre o ComboBox controle. |
| Focalizado | FocusStates | O controle tem foco. |
| Sem foco | FocusStates | O controle não tem foco. |
| Selecionadas | SelectionStates | O item está selecionado atualmente. |
| Não selecionado | SelectionStates | O item não está selecionado. |
| SelectedUnfocused | SelectionStates | O item está selecionado, mas não tem o foco. |
| Válido | ValidationStates | O controle usa a classe e a Validation propriedade anexada Validation.HasError é false. |
| InvalidFocused | ValidationStates | A Validation.HasError propriedade anexada é true tem o controle tem foco. |
| InvalidUnfocused | ValidationStates | A Validation.HasError propriedade anexada é true tem o controle não tem foco. |
