Perhaps you are looking to indent text? Like left and right indent?
If so, then you could just use ReGEtIndent and ReSetIndent methods of the rtf object. 

Here what I do:

<pre><code>//first I find the length of the active window

nLen := REGEtIndent( ::oActive:hWnd ) 
//now resetIndents of the rtf control 
RESetIndent( ::oActive:hWnd, nLen[ 1 ] + 100, nLen[ 2 ] + 100, -25 )
</code></pre>

Hope that helps.

blocks|key|1239674|text|一种快速而简单的方法是通过在窗体加载和窗体/控件调整大小事件时调用此示例方法来从垂直滚动中偏移文本：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1239675|private+void+AdjustTextBoxRMargin()
{
++++richTextBox1.RightMargin+=+richTextBox1.Size.Width+-+35;
}|code-block|syntax|javascript|1239676|值35似乎适用于Win7，但在其他版本的Windows上可能有所不同。|1239677|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

A quick and easy way is to offset text from vertical scroll, by calling this example method at form load and at form/control resize events:

<pre><code>private void AdjustTextBoxRMargin()
{
 richTextBox1.RightMargin = richTextBox1.Size.Width - 35;
}
</code></pre>

The value of 35 seems to work for Win7, but may differ on other versions of Windows.

…look like this:

<img src="https://i.stack.imgur.com/I1xTR.png" alt="enter image description here">

I've written <a href="http://pastebin.com/FnEGqWxX" rel="noreferrer">a small C# extension class</a> to wrap this all up.

Usage example:

<pre><code>const int dist = 24;
richTextBox1.SetInnerMargins(dist, dist, dist, 0);
</code></pre>

This sets the inner margins left, top and right to 24, leaving the bottom as zero.

Please note that when scrolling, the top margin stays as being set, giving something like this:

<img src="https://i.stack.imgur.com/s83cg.png" alt="enter image description here">

Personally, this looks "unnatural" to me. I would prefer that when scrolling the top margin becomes zero, too.

Maybe there is a workaround for that…

Here's an even easier answer. It's not customizable, but it will put a small padding around the entire text -- top, bottom, left and right.

At design time, set the <code>ShowSelectionMargin</code> property of the RichTextBox 
 to <code>True</code>. When you run, you might notice the margin being applied (from no margin to margin), which looks a little "jerkey". If so, put a <code>Me.SuspendLayout</code> in front of loading the RichTextBox, and put a <code>Me.ResumeLayout</code> after.

Here is a simple solution for setting the left and right margins of a RichTextBox that worked well for me in a C# Windows app. It sets both the right and left margins to 4 pixels.
<pre><code>[DllImport(&quot;user32.dll&quot;)]
static extern int SendMessage(IntPtr hWnd, uint wMsg, UIntPtr wParam, IntPtr lParam);

// both left and right margins set to 4 pixels with the last parm: 0x00040004
SendMessage(richtextbox1.Handle, 0xd3, (UIntPtr)0x3, (IntPtr)0x00040004);
</code></pre>
I tried to make the SendMessage more proper below:
<pre><code>const int EM_SETMARGINS = 0xd3;
const int EC_LEFTMARGIN = 0x1;
const int EC_RIGHTMARGIN = 0x2;

SendMessage(richtextbox1.Handle, EM_SETMARGINS,
 (UIntPtr)(EC_LEFTMARGIN | EC_RIGHTMARGIN), (IntPtr)0x00040004);
</code></pre>
I figure this solution was not possible when the question was originally posted.

Is it possible to add padding into a Rich Text Box control between the text and the border?

I tried docking a rich text box inside of a panel, with its padding for all four side set to 10 and that accomplished what I wanted. Except once the vertical scroll bar for the rich text box is needed that gets padded as well.
