How can I scroll a RichText content via code? Please help.

[group@jbli2000.com JBLi]

Hi All,

I need to scroll the content of the RichText control I placed in a
Windows Form by code (C#). Do I need to call native API or can I do so
purely in C#?

Thanks for any hints,

JB.

Hello,

There is not a C# method to scroll the RichTextBox directly. However, you
may workaround it with the following two ways:

1. Call ScrollToCaret method

Set the create position first, and then call the ScrollToCaret method to
scroll to the position. For example:

richTextBox1.Select(richTextBox1.TextLength,0);
richTextBox1.Focus(); //the richtextbox will not scroll if it is
notfocused.
richTextBox1.ScrollToCaret();

2. Send/post WM_VSCROLL message

Call the SendMessage/PostMessage API via PInvoke, and send the proper
WM_VSCROLL message to scroll the RichTextBox

I hope this helps you.
