[英]Adding a 'Label' control to a 'RichTextBox'
I'm having trouble adding a Label
control to a RichTextBox
. 我在将Label
控件添加到RichTextBox
遇到麻烦。 Clearly, there must be something that I'm missing in the code. 显然,代码中肯定缺少某些内容。 I would appreciate it if someone could point out my omission. 如果有人可以指出我的遗漏,我将不胜感激。 I know both of the controls are created, but the Label
is not displayed on top of the RichTexBox
...instead, it's created behind it. 我知道这两个控件均已创建,但是Label
并未显示在RichTexBox
顶部...而是在其后面创建的。
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);
}
In general all you have to do is add a text value to your label! 通常,您要做的就是在标签上添加文本值 ! And you should pay attention to the xy coordinates for each of your controls. 并且您应该注意每个控件的xy坐标。
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
}
And although it is possible to add a label to a RichTextBox
control, I don't think it is very useful! 并且尽管可以 向RichTextBox
控件添加标签 ,但我认为它不是很有用! A RichTextBox
can be used to display and format text : RichTextBox
可用于显示和格式化文本 :
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);
}
