[WPF系列]-TreeView的常用事项

引言

 

项目经常会用Treeview来组织一些具有层级结构的数据,本节就将项目使用Treeview常见的问题作一个总结。

 

DataBinding数据绑定

 

DataTemplate自定义

<HierarchicalDataTemplate DataType="{x:Type viewModels:FieldViewModel}"                                              ItemsSource="{Binding SubViewModels}">                    <StackPanel Orientation="Horizontal">                        <TextBlock Text="F:" Style="{StaticResource IconTextStyle}"                                 Background="LightCoral"/>                        <TextBlock Text="{Binding CurrentEntity.Value.Name}" Focusable="True">                            <TextBlock.ContextMenu>                                <ContextMenu>                                    <MenuItem Header="New Well" Command="{Binding AddCommand}"                                          CommandParameter="{Binding Path=CurrentEntity.Value}" />                                    <MenuItem Header="Delete" Command="{Binding DeleteCommand}"                                          CommandParameter="{Binding Path=CurrentEntity.Value}" />                                </ContextMenu>                            </TextBlock.ContextMenu>                        </TextBlock>                    </StackPanel>                </HierarchicalDataTemplate>

Style自定义

 

 

 

Events顺序

SelectedItemChanged 发生在TreeView向新selectedItem聚焦(set focus on its new selected item).

一句话: selectedItemChanged –>set foucs on the new selected item.
