Estilos e modelos ListView

  • Artigo

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.
