將「標籤」控件添加到「RichTextBox」

Question

我在添加Label控件到RichTextBox時遇到問題。很明顯，我必須在代碼中缺少某些東西。如果有人能指出我的疏忽，我將不勝感激。我知道這兩個控件都已創建，但Label未顯示在RichTexBox的頂部......相反，它在之後創建了。

RichTextBox richBox8; 
Label label8; 

private void create() 
{ 
    richBox8 = new RichTextBox(); 
    richBox8.Location = new System.Drawing.Point(957, 95); 
    richBox8.Size = new System.Drawing.Size(159, 50); 
    richBox8.Name = "richTextBox8"; 
    Controls.Add(richBox8); 

    label8 = new Label(); 
    label8.Location = new System.Drawing.Point(984, 106); 
    label8.Name = "label8"; 
    label8.Size = new System.Drawing.Size(110, 25); 
    label8.Text = "" 
    Controls.Add(label8); 
    richBox8.Controls.Add(label8); 
}

一般而言，所有你需要做的就是文本值添加到您的標籤！並且您應該注意每個控件的x-y座標。

RichTextBox richBox8 = null; 
Label label8 = null; 
private void button1_Click(object sender, EventArgs e) 
{ 
    richBox8 = new RichTextBox(); 
    richBox8.Location = new System.Drawing.Point(1, 1); 
    richBox8.Size = new System.Drawing.Size(300, 200); 
    richBox8.Name = "richTextBox8"; 
    Controls.Add(richBox8); 

    label8 = new Label(); 
    label8.Location = new System.Drawing.Point(5, 5); 
    label8.Name = "label8"; 
    label8.Size = new System.Drawing.Size(110, 25); 
    label8.Text = "hello world"; // crucial, if there is no text, you won't see any label! 
    richBox8.Controls.Add(label8); 
    // adding the label once again to the form.Controls collection is unnecessary 
} 

雖然它是可能的標籤添加到RichTextBox控制，我不認爲它是非常有用的！一個RichTextBox可以用來顯示和格式文本：

public Form1() 
{ 
    InitializeComponent(); 
    richTextBox1.Text = "demo text demo text demo text demo text demo text demo text demo text demo text demo text demo text demo text demo text "; 
} 

private void button1_Click(object sender, EventArgs e) 
{ 
    richTextBox1.Select(10, 20); 
    richTextBox1.SelectionColor = Color.Blue; 

    richTextBox1.Select(25, 30); 
    richTextBox1.SelectionFont = new Font("Verdana", 12); 
}
