Append text on rtf string at position

Question

I want to append text, for example "World" in a textbox, but not with the Windows.Forms functions for RichTextBox. Instead i want to specify position and the string that i want to insert into Rtf property of the RichTextBox! So, is it possible to update the rtf string directly ?

Answer 1

string rtfStuffs = this.richTextBox1.Rtf;
// Edit as you see fit...
this.richTextBox1.Rtf = rtfStuffs;
