常用属性 | 描述 |
---|---|
ItemsSource | 用于设置ListView的数据源。可以是一个集合、数组或列表等。 |
ItemTemplate | 用于设置ListView中每个项目的模板。可以通过DataTemplate定义项目的外观和内容。 |
ItemContainerStyle | 用于设置ListView中每个项目容器的样式。可以通过Style定义项目容器的外观和行为。 |
SelectedItem | 用于获取或设置当前选中的项目。 |
SelectionMode | 用于设置ListView的选择模式。可以是单选、多选或无选择。 |
GridViewColumn | 用于设置ListView的列定义。可以通过GridViewColumn定义列的标题、宽度和数据模板。 |
HeaderContainerStyle | 用于自定义GridViewColumn列标题容器的外观和行为。比如让所有列的标题靠左 |
SelectedIndex | 用于获取或设置当前选中项目的索引。,如果没有选中任何项,则返回-1 |
SelectedItems | 用于获取当前选中的多个项目。与SelectedItem的区别就是它可以获取多个选中项目。 |
ScrollViewer | 用于设置ListView的滚动视图器。可以用ScrollViewer设置滚动条的样式和行为。 |
ContextMenu | 用于设置ListView的上下文菜单。可以用ContextMenu定义项目的右键菜单。 |
AlternationCount | 用于指定交替行的数量。当 AlternationCount 设置为大于 1 的值时,ListView 会自动为交替行应用不同的背景色,一般设置为2。 |
GridViewColumnHeader.Click | 视图 GrudVuew 列标题头点击事件。 |
