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

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:

<pre><code>// 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);
</code></pre>

I found this Post when searching through the web because I am facing the exact same problem.

However, appending a white space to the end of the node was not an option, and I found an alternative way that seems to fix the issue.

After setting my node font Bold, all I need to do is reset the node text with the same value.

Here is the Code Sample:

<pre><code>Font boldFont = new Font(treeview.Font, FontStyle.Bold);
node.NodeFont = boldFont;
node.Text = node.Text;
</code></pre>

It seems that the node is redrawn after changing the text, which is exactly what I wanted in the first place.

blocks|key|1112868|text|只需在加粗节点之前使用treeView.BeginUpdate()，然后在加粗节点之后使用treeView.EndUpdate()。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1112869|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Simply use treeView.BeginUpdate() before you bold the node then treeView.EndUpdate() after you've bolded the node.

blocks|key|1327434|text|这是一个已知的Windows错误。简单的解决方案是在字符串的末尾附加一个额外的空格字符。空格字符将不可见，但它将增加绘制字符串所需的像素数，因此整个字符串将可见。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1327435|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This is a known Windows bug.
The simple solution is just to append an extra space character at the end of your strings. The space character will not be visible, but it will increase the number of pixels needed to draw the string, so the entire string will be visible.

blocks|key|1327610|text|这一切对我都没有帮助。这个技巧就是在设计时让字体变得更大、更粗。(在属性窗口中)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1327611|因此，请确保使用足够大的字体定义treeview，然后可以使用较小的字体添加节点。它们会合身的。|1327612|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

This is all not helping for me. 
What DID the trick is making the font a little bigger and bold at DESIGN time.
(In the Properties window)

So make sure you define the treeview with big enough font, then later you can add nodes with smaller font. They will fit.

blocks|key|1112601|text|我确实同意所提供的解决方案。我只是想补充一下，以便更清楚地说明问题是什么。treeview有它自己的字体，它决定了项目在根级别的宽度。这弥补了只有一个项目高度属性可用而没有项目宽度属性的事实。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1112602|问题的解决方案是确定根节点的字体应该是什么，然后将树设置为相同的字体。您也可以在设计时这样做。|1112603|希望这能帮助到一些人。|1112604|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I do agree with the solution provided. I just want to add to it to shed a little more light on what the problem is. 
The treeview has its own font which determines the width of items at the root level. That compensates for the fact that there is only an item height property available and no item width property.

The solution to your problem is to determine what the font of your root node should be, then set the tree to that same font. You can do that at design time also.

Hope that helps someone.

blocks|key|1327749|text|此问题的解决方法如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1327750|在属性中将treeview的默认字体设置为粗体。|1327751|当你需要的时候，不要太大胆。|1327752|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

A workaround for this problem is this:

Set the defaul font of treeview to bold in the properties.

And chnage to not bold when you need.

blocks|key|1112937|text|我执行以下操作，将DrawNode事件设置为call，它将节点设置为粗体并删除突出显示的颜色。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1112938|您可以使用e.Graphics.FillRectangle函数的第一个参数设置您喜欢的任何颜色。|1112939|private+void+SetNodeBoldWhenSelected(object+sender,+DrawTreeNodeEventArgs+e)

}|code-block|syntax|javascript|1112940|现在，当我选择一个节点时，我得到了20个像素的额外空间，对于我的字体来说，这很有效，可以计算出所需的“实际”大小，但是没有说明需要这样做，但是如果你觉得需要这样做，你可以使用Graphics.MeasureString。|1112941|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I do the following, I set the DrawNode Event to call, it sets the node to bold and removes the highlighted colour.

You can set any colour you like using the first parameter of the e.Graphics.FillRectangle function.

<pre><code>private void SetNodeBoldWhenSelected(object sender, DrawTreeNodeEventArgs e)
{
 if (e.Node == null) return;
 var font = e.Node.NodeFont ?? e.Node.TreeView.Font;
 if (e.Node.IsSelected)
 {
 font = new Font(font, FontStyle.Bold); 
 }

 var bounds = new Rectangle( e.Bounds.X,e.Bounds.Y,e.Bounds.Width+20,e.Bounds.Height);

 e.Graphics.FillRectangle(SystemBrushes.ControlDarkDark, bounds);
 TextRenderer.DrawText(e.Graphics, e.Node.Text, font, bounds, SystemColors.HighlightText, TextFormatFlags.GlyphOverhangPadding);
}
</code></pre>

Now when I select a node I get 20 pixels more space, for my font, this works well, one can calculate the "real" size needed but there is no specification stating it needs to do this but you can use Graphics.MeasureString if you feel you need to do that.

blocks|key|1112710|text|我意识到这是一个古老的帖子，它可能已经被回答了。我在学习使用TreeViews的时候遇到了这个问题。对我有效的是将整个TreeView的字体大小更改为相同的大小，或者比您想要加粗的级别的字体更大。默认的字体大小是8.thing。我将我的更改为10，这是我想要的节点大小，截断就消失了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1112711|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I realize this is an old thread and it may have been answered. I just ran across this problem as I'm learning to use TreeViews. What worked for me was changing the font size for the entire TreeView to the same size, or bigger than the font of the level you want to bold. The default font size is 8.something. I changed mine to 10, which was the size I wanted my nodes, and the truncating was gone.

blocks|key|1112761|text|对我有效的方法:连接到控件的构造函数中的load事件，并调整节点，如布朗特的回答中所述。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1112762|public+MyControl()

++++_head+=+new+TreeNode();

++++this.Load+%2B=+(s,+e)+=>

What worked for me: Hooking into the load event in the Control's constructor and tweaking the node as explained in BlunT's answer.

<pre><code>public MyControl()
{
 InitializeComponent();
 _head = new TreeNode();

 this.Load += (s, e) =&gt;
 {
 trvParts.Nodes.Clear();
 _head.NodeFont = new Font(trvParts.Font, FontStyle.Bold);
 trvParts.Nodes.Add(_head);
 _head.Text = "Node Name";
 };
}

It's in vb.Net however the solution to re-enter the value of the TEXT field gets around this nicely. As in:
