The following code example adds a RichTextBox control to the top of the worksheet, assigns text to the control, and then formats the text. To use this example, run it from the Sheet1 class in a document-level project.

Private Sub ExcelRangeAddRichTextBox()

    Dim RichTextBox1 As Microsoft.Office.Tools. _
        Excel.Controls.RichTextBox = Me.Controls. _
        AddRichTextBox(Me.Range("A1", "B2"), _
        "RichTextBox1")

    RichTextBox1.Text = "Sample text"
    RichTextBox1.Select(0, 6)
    RichTextBox1.SelectionFont = New Font( _
        "Times New Roman", 10, FontStyle.Bold)

End Sub
private void ExcelRangeAddRichTextBox()
{

    Microsoft.Office.Tools.Excel.Controls.RichTextBox
         richTextBox1 = this.Controls.AddRichTextBox(
         this.Range["A1", "B2"], "richTextBox1");
    richTextBox1.Text = "Sample text";
    richTextBox1.Select(0, 6);
