如何在运行时将文本框添加到richtextbox [英] how to add textbox to richtextbox at runtime

问题描述

我有新的问题要问是否有人可以帮助我(自从我上次问前一段时间解决的同一件事时，我需要进行脑部检查:P:P:D :)

无论如何

我在表单上有richtextbox，我试图在运行时在鼠标右键单击上动态放置文本框，我有这段代码，但没有任何反应

I have something new to ask if anybody can help me(I need braincheck since the last time I asked the very same thing I got solved some time ago :P :P :D :)

anyway

I have richtextbox on the form and I am trying to put at run time dynamically textboxes on right click of the mouse, I have this code but nothing happens

if (e.Button == MouseButtons.Right)
            {
                int c = 0;

                TextBox newtext= new TextBox();
                newtext.Name = "newtext" + c++;
                newtext.Location = new Point(e.X, e.Y);
                newtext.Size = new System.Drawing.Size(200, 25);
                this.Controls.Add(newtext);


            }

事情是我在richtextbox中键入文本，然后我想在我输入的某些单词之间放置文本框，当光标在该单词或诸如此类的单词后面时，是否有一种更简单的方法来实现呢?

thing is that I am typing text in richtextbox and then I want to place textbox between some words that I typed, is there a easier way to do it when cursor is behind the word or something like that

推荐答案

如果要添加到richTextBox，请添加到Richtextbox.controls，而不是this.controls

if you want to add to richTextBox add to Richtextbox.controls not this.controls

private void richTextBox1_MouseDown(object sender, MouseEventArgs e)
       {

           if (e.Button == MouseButtons.Right)
           {
               int c = 0;

               TextBox newtext = new TextBox();
               newtext.Name = "newtext" + c++;
               newtext.Location = new Point(e.X, e.Y);
               newtext.Size = new System.Drawing.Size(200, 25);
               richTextBox1.Controls.Add(newtext);
               //this.Controls.Add(newtext);


           }
       }

我试过了，它可以正常工作
再次检查并确保此代码块位于side richTextBox_MouseDown
不在Form1_MouseDown

i tried it it is working
check it again and be sure that this code block in side richTextBox_MouseDown
not in side Form1_MouseDown
