Hide scrollbars of a RichTextBox

Question

I\'m trying to write a simple text editor like DarkRoom with just a RichTextBox (or alternatively a TextBox) in it. My problem is that I can\'t use the mouse wheel for scrol

Answer 1

Yes, you will have to capture the .MouseWheel and .MouseMove events. See this post.

Ok, do something like following:

1. Add a line in form load event.

   private void Form1_Load(object sender, EventArgs e)
   {
       this.richTextBox1.MouseWheel += new MouseEventHandler(richTextBox1_MouseWheel);
   }
   

2. Add following in mouse wheel event.

   void richTextBox1_MouseWheel(object sender, MouseEventArgs e)
   {
       if (e.Delta > 0)
       {
           //Handle mouse move upwards
           if (richTextBox1.SelectionStart > 10)
           {
               richTextBox1.SelectionStart -= 10;
               richTextBox1.ScrollToCaret();
           }
       }
       else
       {
           //Mouse move downwards.
           richTextBox1.SelectionStart += 10;
           richTextBox1.ScrollToCaret();
       }
   }
   

Let me know in either cases, if you would want the running sample of the same; or if you are not liking the solution (0:
