[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.
