在WPF树视图节点设置父字体为粗体使用code背后 [英] Setting font of parent in nodes in WPF Tree View to Bold using code behind

问题描述

我已经做了一个树视图，并添加父和子节点，它全部采用落后code，现在我在哪里卡住是设置父节点的字体粗体，同时保持孩子的字体，因为它是，下面是code，我现在所拥有的。

I have made a tree view and added parent and child nodes to it all using code behind, now where I am stuck is to set the font of parent nodes to BOLD while keeping the font of child as it is, below is code that i have right now.

 List<ParentTreeViewNode> ParentTreeViewNodeList = new List<ParentTreeViewNode>();

                HierarchicalDataTemplate treeViewTemplate = new HierarchicalDataTemplate(typeof(Child));
                treeViewTemplate.DataType = "{x:Type local:Child}";
                treeViewTemplate.ItemsSource = new Binding("Children");

                FrameworkElementFactory tb = new FrameworkElementFactory(typeof(TextBlock));
                tb.SetBinding(TextBlock.TextProperty, new Binding("Name"));
                tb.SetValue(TextBlock.ForegroundProperty, Brushes.Yellow);
                treeViewTemplate.VisualTree = tb;

                DataTemplate parentTemplate = new DataTemplate(typeof(ParentTreeViewNode));
                parentTemplate.DataType = "{x:Type local:ParentTreeViewNode}";
                //parentTemplate.ItemsSource = new Binding("Children");

                FrameworkElementFactory tbp = new FrameworkElementFactory(typeof(TextBlock));
                tbp.SetBinding(TextBlock.TextProperty, new Binding("Name"));
                tbp.SetValue(TextBlock.ForegroundProperty, Brushes.Green);
                treeViewTemplate.VisualTree = tbp;


                // ParentTreeViewNode1.Children = Childlist1;
                ;
                ParentTreeViewNodeList.Add(new ParentTreeViewNode("Paren1"));
                ParentTreeViewNodeList.Add(new ParentTreeViewNode("Paren2"));
                ParentTreeViewNodeList.Add(new ParentTreeViewNode("Paren3"));

                //arrayTreeView.ItemTemplate = treeViewTemplate;
                arrayTreeView.Resources.Add(1,treeViewTemplate);
                arrayTreeView.Resources.Add(2,treeViewTemplate);
                arrayTreeView.ItemsSource = ParentTreeViewNodeList;

推荐答案

试试这个

  <ControlTemplate TargetType="{x:Type TreeViewItem}">
                    <Grid>
                        --------------
                        --------------
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="HasItems" Value="true">
                            <Setter TargetName="PART_Header"
                                    Property=" TextElement.FontWeight"
                                    Value="Bold"/>
                        </Trigger>                           
                    </ControlTemplate.Triggers>
                </ControlTemplate>

复制默认模板并添加此trigger.I我不知道如何做到这一点在code.You可以查看这篇文章得到一些概述

Copy the default template and add this trigger.I am not sure how to do this in code.You can check this article to get some overview
