Remarks

Use a GroupContentControl to define a protected region of a document that users cannot edit or delete. A GroupContentControl can contain any document items, such as text, tables, graphics, and even other content controls. A GroupContentControl provides no UI that is visible to the user. For more information about using a GroupContentControl to protect a part of a document, see Content Controls and How to: Protect Parts of Documents by Using Content Controls.

Note

This interface is implemented by the Visual Studio Tools for Office runtime. It is not intended to be implemented in your code. For more information, see Visual Studio Tools for Office Runtime Overview.

Content Controls

The GroupContentControl is one of eight types of content controls that you can use to design documents and templates in Microsoft Office Word. Content controls have a user interface (UI) that has controlled input like a form. You can use content controls to prevent users from editing protected sections of the document or template, and you can also bind content controls to a data source. For more information, see Content Controls.

Usage

This documentation describes the version of this type that is used in Office projects that target the .NET Framework 4 and the .NET Framework 4.5. In projects that target the .NET Framework 3.5, this type might have different members and the code examples provided for this type might not work. For documentation about this type in projects that target the .NET Framework 3.5, see the following reference section in the Visual Studio 2008 documentation: https://go.microsoft.com/fwlink/?LinkId=160658.

Examples

The following code example adds a new paragraph to the beginning of the document, and it creates a new GroupContentControl that contains this paragraph. The GroupContentControl prevents users from editing the text in the paragraph.

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. 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");
}
