Examples

The following code example adds a new paragraph to the beginning of the document, and it creates a GroupContentControl that contains this paragraph. 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 AddGroupControlAtRange method from the ThisDocument_Startup method.

Dim groupControl2 As Microsoft.Office.Tools.Word.GroupContentControl

Private Sub AddGroupControlAtRange()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Dim range1 As Word.Range = Me.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()
    groupControl2 = Me.Controls.AddGroupContentControl(range1, "groupControl2")
End Sub

private Microsoft.Office.Tools.Word.GroupContentControl groupControl2;

private void AddGroupControlAtRange()
{
    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();

    groupControl2 = this.Controls.AddGroupContentControl(range1, "groupControl2");
}

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 AddGroupControlAtRange method from the ThisAddIn_Startup method.

Dim groupControl2 As Microsoft.Office.Tools.Word.GroupContentControl

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

    Dim vstoDoc As Document = Me.Application.ActiveDocument.GetVstoObject()
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    Dim range1 As Word.Range = 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()
    groupControl2 = vstoDoc.Controls.AddGroupContentControl(range1, "groupControl2")
End Sub

private Microsoft.Office.Tools.Word.GroupContentControl groupControl2;

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

    Document vstoDoc = this.Application.ActiveDocument.GetVstoObject();
    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();

    groupControl2 = vstoDoc.Controls.AddGroupContentControl(range1, "groupControl2");
}
