Examples

The following code example adds a new RichTextContentControl to the beginning of the document.

This version is for a document-level customization. To use this code, paste it into the ThisDocument class in your project, and call the AddRichTextControlAtSelection method from the ThisDocument_Startup method.

Dim richTextControl1 As Microsoft.Office.Tools.Word.RichTextContentControl

Private Sub AddRichTextControlAtSelection()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Me.Paragraphs(1).Range.Select()
    richTextControl1 = Me.Controls.AddRichTextContentControl("richTextControl1")
    richTextControl1.PlaceholderText = "Enter your first name" 
End Sub

private Microsoft.Office.Tools.Word.RichTextContentControl richTextControl1;

private void AddRichTextControlAtSelection()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    this.Paragraphs[1].Range.Select();

    richTextControl1 = this.Controls.AddRichTextContentControl("richTextControl1");
    richTextControl1.PlaceholderText = "Enter your first name";
}

This version is for an application-level add-in. To use this code, paste it into the ThisAddIn class in your project, and call the AddRichTextControlAtSelection method from the ThisAddIn_Startup method.

Dim richTextControl1 As Microsoft.Office.Tools.Word.RichTextContentControl

Private Sub AddRichTextControlAtSelection()
    If Me.Application.ActiveDocument Is Nothing Then 
        Return 
    End If 

    Dim vstoDoc As Document = Me.Application.ActiveDocument.GetVstoObject()
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    vstoDoc.Paragraphs(1).Range.Select()
    richTextControl1 = vstoDoc.Controls.AddRichTextContentControl("richTextControl1")
    richTextControl1.PlaceholderText = "Enter your first name" 
End Sub

private Microsoft.Office.Tools.Word.RichTextContentControl richTextControl1;

private void AddRichTextControlAtSelection()
{
    if (this.Application.ActiveDocument == null)
        return;

    Document vstoDoc = this.Application.ActiveDocument.GetVstoObject();
    vstoDoc.Paragraphs[1].Range.InsertParagraphBefore();
    vstoDoc.Paragraphs[1].Range.Select();

    richTextControl1 = vstoDoc.Controls.AddRichTextContentControl("richTextControl1");
    richTextControl1.PlaceholderText = "Enter your first name";
}
