C＃的WinForms大胆TreeView节点不显示全文 [英] C# Winforms bold treeview node doesn't show whole text

问题描述

我用下面的代码，使我的TreeNode大胆：

I'm using the following code to make my treenodes bold:

Font font = new Font(tvQuestionSequence.Font, FontStyle.Bold);

foreach (QuestionnaireBuilder_Category cat in categories)
{
    TreeNode node = new TreeNode();

    node.Text = cat.Description;
    node.Name = cat.Id.ToString();

    node.NodeFont = font;

    tvQuestionSequence.Nodes.Add(node);
}

但大胆节点的文本无法正确显示。最后一个字母（S）没有显示。怎么来的？而如何解决这个问题？

But the text of the bold nodes is not displayed correctly. The last letter(s) are not shown. How come? And how to solve this problem?

推荐答案

我发现，这是Windows的问题。此问题的解决方法是这样的：

I've found that this is a Windows issue. A workaround for this problem is this:

在表单构造树视图的字体设置为粗体。当添加不可为大胆的节点，改变字体常规：

In the form constructor set the font of the treeview to bold. When adding nodes which must not be bold, change the font to regular:

// Constructor of your form
public Form() 
{
    InitializeComponent();

    Font font = new Font(tvQuestionSequence.Font, FontStyle.Bold);
    tvQuestionSequence.Font = font;
}

// Add regular nodes (not bold)
Font font = new Font(tvQuestionSequence.Font, FontStyle.Regular);

TreeNode treeNode = new TreeNode();
treeNode.Text = "Foo";
treeNode.NodeFont = font;

TreeNode parent = tvQuestionSequence.Nodes.Find("parent", true);
parent.Nodes.Add(treeNode);
