  The ContentControl that is the basis for the new control.

• name
  Type: System.String

  The name of the new control.

Return Value

Type: Microsoft.Office.Tools.Word.RichTextContentControl
The RichTextContentControl that was added to the document.

Exceptions

Exception	Condition
ArgumentNullException	contentControl is nulla null reference (Nothing in Visual Basic). -or- name is nulla null reference (Nothing in Visual Basic) or has zero length.
ControlNameAlreadyExistsException	A control with the same name is already in the ControlCollection.
ArgumentException	contentControl is not a building block gallery (that is, the Microsoft.Office.Interop.Word.ContentControl.Type property of contentControl does not have the value Microsoft.Office.Interop.Word.WdContentControlType.wdContentControlRichText).

Remarks

Use this method to add a new RichTextContentControl that is based on a native content control in the document at run time. This is useful when you create a RichTextContentControl at run time, and you want to recreate the same control the next time the document is opened. For more information, see Adding Controls to Office Documents at Run Time.

Examples

The following code example creates a new RichTextContentControl for every native rich text control that is in 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 CreateRichTextControlsFromNativeControls method from the ThisDocument_Startup method.

Private richTextControls As New System.Collections.Generic.List _
        (Of Microsoft.Office.Tools.Word.RichTextContentControl)

Private Sub CreateRichTextControlsFromNativeControls()
    If Me.ContentControls.Count <= 0 Then 
        Return 
    End If 

    Dim count As Integer = 0
    For Each nativeControl As Word.ContentControl In Me.ContentControls
        If nativeControl.Type = Word.WdContentControlType.wdContentControlRichText Then
            count += 1
            Dim tempControl As Microsoft.Office.Tools.Word.RichTextContentControl = _
                Me.Controls.AddRichTextContentControl(nativeControl, _
                "VSTORichTextContentControl" + count.ToString())
            richTextControls.Add(tempControl)
        End If 
    Next nativeControl
End Sub

    <Microsoft.Office.Tools.Word.RichTextContentControl> richTextControls;

private void CreateRichTextControlsFromNativeControls()
{
    if (this.ContentControls.Count <= 0)
        return;

    richTextControls = new System.Collections.Generic.List
        <Microsoft.Office.Tools.Word.RichTextContentControl>();
    int count = 0;

    foreach (Word.ContentControl nativeControl in this.ContentControls)
    {
        if (nativeControl.Type ==
            Microsoft.Office.Interop.Word.WdContentControlType.wdContentControlRichText)
        {
            count++;
            Microsoft.Office.Tools.Word.RichTextContentControl tempControl =
                this.Controls.AddRichTextContentControl(nativeControl,
                "VSTORichTextControl" + count.ToString());
            richTextControls.Add(tempControl);
        }
    }
}

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 CreateRichTextControlsFromNativeControls method from the ThisAddIn_Startup method.

The following code example creates a new RichTextContentControl for every native rich text control that the user adds to the document.

This version is for a document-level customization. To use this code, paste it into the ThisDocument class in your project. For C#, you must also attach the ThisDocument_RichTextContentControlAfterAdd event handler to the ContentControlAfterAdd event of the ThisDocument class.

Private Sub ThisDocument_RichTextContentControlAfterAdd(ByVal NewContentControl As Word.ContentControl, _
    ByVal InUndoRedo As Boolean) Handles Me.ContentControlAfterAdd

    If NewContentControl.Type = Word.WdContentControlType.wdContentControlRichText Then 
        Me.Controls.AddRichTextContentControl(NewContentControl, _
            "RichTextControl" + NewContentControl.ID)
    End If 
End Sub

void ThisDocument_RichTextContentControlAfterAdd(Word.ContentControl NewContentControl, bool InUndoRedo)
{
    if (NewContentControl.Type == Word.WdContentControlType.wdContentControlRichText)
    {
        this.Controls.AddRichTextContentControl(NewContentControl,
            "RichTextControl" + NewContentControl.ID);
    }
}

This version is for an application-level add-in. To use this code, paste it into the ThisAddIn class in your project. Also, you must attach the ActiveDocument_RichTextContentControlAfterAdd event handler to the ContentControlAfterAdd event of the active document.

Private Sub ActiveDocument_RichTextContentControlAfterAdd( _
    ByVal NewContentControl As Word.ContentControl, _
    ByVal InUndoRedo As Boolean)

    Dim vstoDoc As Document = Me.Application.ActiveDocument.GetVstoObject()
    If NewContentControl.Type = Word.WdContentControlType. _
        wdContentControlRichText Then
        vstoDoc.Controls.AddRichTextContentControl(NewContentControl, _
            "RichTextControl" + NewContentControl.ID)
    End If 
End Sub

void ActiveDocument_RichTextContentControlAfterAdd(
    Word.ContentControl NewContentControl, bool InUndoRedo)
{            
    Document vstoDoc = this.Application.ActiveDocument.GetVstoObject();
    if (NewContentControl.Type == Word.WdContentControlType.wdContentControlRichText)
    {
        vstoDoc.Controls.AddRichTextContentControl(NewContentControl,
            "RichTextControl" + NewContentControl.ID);
    }
}
