The GroupContentControl prevents users from editing the text in the paragraph. For more information about using a GroupContentControl to protect a part of a document, see Content Controls.

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

Dim groupControl1 As Microsoft.Office.Tools.Word.GroupContentControl

Private Sub AddGroupControlAtSelection()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Me.Paragraphs(1).Range.Text = "You cannot edit or change the formatting of text " & _
            "in this paragraph, because this paragraph is in a GroupContentControl."
    Me.Paragraphs(1).Range.Select()
    groupControl1 = Me.Controls.AddGroupContentControl("groupControl1")
End Sub

private Microsoft.Office.Tools.Word.GroupContentControl groupControl1;

private void AddGroupControlAtSelection()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    Word.Range range1 = this.Paragraphs[1].Range;
    range1.Text = "You cannot edit or change the formatting of text " +
        "in this paragraph, because this paragraph is in a GroupContentControl.";
    range1.Select();

    groupControl1 = this.Controls.AddGroupContentControl("groupControl1");
}

This version is for an application-level add-in that targets the .NET Framework 4. To use this code, paste it into the ThisAddIn class in your project, and call the AddGroupControlAtSelection method from the ThisAddIn_Startup method.

Dim groupControl1 As Microsoft.Office.Tools.Word.GroupContentControl

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

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    vstoDoc.Paragraphs(1).Range.Text = "You cannot edit or change the formatting of text " & _
            "in this paragraph, because this paragraph is in a GroupContentControl."
    vstoDoc.Paragraphs(1).Range.Select()
    groupControl1 = vstoDoc.Controls.AddGroupContentControl("groupControl1")
End Sub

private Microsoft.Office.Tools.Word.GroupContentControl groupControl1;

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

    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    vstoDoc.Paragraphs[1].Range.InsertParagraphBefore();
    Word.Range range1 = vstoDoc.Paragraphs[1].Range;
    range1.Text = "You cannot edit or change the formatting of text " +
        "in this paragraph, because this paragraph is in a GroupContentControl.";
    range1.Select();

    groupControl1 = vstoDoc.Controls.AddGroupContentControl("groupControl1");
}
