ControlCollection.AddBuildingBlockGalleryContentControl Method (ContentControl, String)

Adds a new BuildingBlockGalleryContentControl to the collection. The new control is based on a native content control that is already in the document.

Namespace:  Microsoft.Office.Tools.Word
Assembly:  Microsoft.Office.Tools.Word (in Microsoft.Office.Tools.Word.dll)

Syntax

'Declaration
Function AddBuildingBlockGalleryContentControl ( _
    contentControl As ContentControl, _
    name As String _
) As BuildingBlockGalleryContentControl

BuildingBlockGalleryContentControl AddBuildingBlockGalleryContentControl(
    ContentControl contentControl,
    string name
)

Parameters

• contentControl
  Type: Microsoft.Office.Interop.Word.ContentControl
  The Microsoft.Office.Interop.Word.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.BuildingBlockGalleryContentControl
The BuildingBlockGalleryContentControl 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 Type property of contentControl does not have the value Microsoft.Office.Interop.Word.WdContentControlType.wdContentControlBuildingBlockGallery).

Remarks

Use this method to add a new BuildingBlockGalleryContentControl that is based on a native content control in the document. This is useful when you create a BuildingBlockGalleryContentControl 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 BuildingBlockGalleryContentControl for every native building block gallery that is already 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 CreateBuildingBlockControlsFromNativeControls method from the ThisDocument_Startup method.

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

Private Sub CreateBuildingBlockGalleryControlsFromNativeControls()
    If Me.ContentControls.Count <= 0 Then

    Dim count As Integer = 0
    For Each nativeControl As Word.ContentControl In Me.ContentControls
        If nativeControl.Type = Word.WdContentControlType.wdContentControlBuildingBlockGallery Then

            Dim tempControl As Microsoft.Office.Tools.Word.BuildingBlockGalleryContentControl = _
                Me.Controls.AddBuildingBlockGalleryContentControl(nativeControl, _
                "VSTOBuildingBlockGalleryContentControl" + count.ToString())
            buildingBlockControls.Add(tempControl)
        End If
    Next nativeControl

        return;

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

    foreach (Word.ContentControl nativeControl in this.ContentControls)
    {
        if (nativeControl.Type == Word.WdContentControlType.wdContentControlBuildingBlockGallery)
        {
            count++;
            Microsoft.Office.Tools.Word.BuildingBlockGalleryContentControl tempControl =
                this.Controls.AddBuildingBlockGalleryContentControl(nativeControl,
                "VSTOBuildingBlockContentControl" + count.ToString());
            buildingBlockControls.Add(tempControl);
        }
    }
}

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 add-in project, and call the CreateBuildingBlockControlsFromNativeControls method from the ThisAddIn_Startup method.

The following code example creates a new BuildingBlockGalleryContentControl for every native building block gallery 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_BuildingBlockContentControlAfterAdd event handler to the ContentControlAfterAdd event of the ThisDocument class.

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

    If NewContentControl.Type = Word.WdContentControlType.wdContentControlBuildingBlockGallery Then
        Me.Controls.AddBuildingBlockGalleryContentControl(NewContentControl, _
            "BuildingBlockControl" + NewContentControl.ID)
    End If
End Sub

void ThisDocument_BuildingBlockContentControlAfterAdd(Word.ContentControl NewContentControl, bool InUndoRedo)
{
    if (NewContentControl.Type == Word.WdContentControlType.wdContentControlBuildingBlockGallery)
    {
        this.Controls.AddBuildingBlockGalleryContentControl(NewContentControl,
            "BuildingBlockControl" + NewContentControl.ID);
    }
}

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. Also, you must attach the ActiveDocument_BuildingBlockContentControlAfterAdd event handler to the ContentControlAfterAdd event of the active document.

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

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    If NewContentControl.Type = Word.WdContentControlType. _
        wdContentControlBuildingBlockGallery Then
        vstoDoc.Controls.AddBuildingBlockGalleryContentControl(NewContentControl, _
            "BuildingBlockControl" + NewContentControl.ID)
    End If
End Sub

void ActiveDocument_BuildingBlockContentControlAfterAdd(
    Word.ContentControl NewContentControl, bool InUndoRedo)
{
    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    if (NewContentControl.Type == Word.WdContentControlType.wdContentControlBuildingBlockGallery)
    {
        vstoDoc.Controls.AddBuildingBlockGalleryContentControl(NewContentControl,
            "BuildingBlockControl" + NewContentControl.ID);
    }
}
