Do you really want plain text? You can use the RichTextBox in a DataGridView column. See:
http://www.codeproject.com/KB/grid/RtfInDataGridView.aspx

If you do want plain text you can use an instance of the RichTextBox to do the conversion:

System.Windows.Forms.RichTextBox rtb = new System.Windows.Forms.RichTextBox();
rtb.Rtf =  (the RTF string)
string plainText = rtb.Text;
