  • Article

Occurs when the user deletes a Microsoft.Office.Interop.Word.XMLNode or descendent node from the collection, before the control is deleted.

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

Syntax

'Declaration
Event BeforeDelete As NodeInsertAndDeleteEventHandler

event NodeInsertAndDeleteEventHandler BeforeDelete

Remarks

If the InUndoRedo parameter is true, you should not change the XML in the document.

Examples

The following code example demonstrates event handlers for the AfterInsert and BeforeDelete events. The code displays a message box before a Microsoft.Office.Interop.Word.XMLNode is deleted from the document and after a Microsoft.Office.Interop.Word.XMLNode is added to the document. The example also uses the Add method to add a new element to an XMLNodes collection at a specified range and programmatically raise the AfterInsert event. This example assumes that the current document contains an XMLNodes collection named SampleInsertNodes, which has a parent XMLNode named SampleNode.

Private Sub XMLNodeAddAndDelete()
    Dim range1 As Object = Me.SampleInsertNodes(1).Range

    ' This will raise the AfterInsert event.
    Dim node1 As Word.XMLNode = _
        Me.SampleInsertNodes.Add("MemoFrom", _
        Me.SampleNode.NamespaceURI, range1)
End Sub

Private Sub SampleInsertNodes_AfterInsert(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs)


    If e.InUndoRedo Then
        MessageBox.Show("A child element of SampleInsertNodes was " & _
            "inserted as a result of an undo or redo operation.")
    Else
        MessageBox.Show("A child element of SampleInsertNodes " & _
            "was inserted.")
    End If
End Sub

Private Sub SampleInsertNodes_BeforeDelete(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs)


    If e.InUndoRedo Then
        MessageBox.Show("A child element of SampleInsertNodes " & _
            "is about to be deleted as a result of an undo or " & _
            "redo operation.")
    Else
        MessageBox.Show("A child element of SampleInsertNodes " & _
        "is about to be deleted.")
    End If
End Sub

private void XMLNodeAddAndDelete()
{
    object range1 = this.SampleInsertNodes[1].Range;

    this.SampleInsertNodes.AfterInsert +=
        new Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventHandler(
        SampleInsertNodes_AfterInsert);

    this.SampleInsertNodes.BeforeDelete +=
        new Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventHandler(
        SampleInsertNodes_BeforeDelete);

    // This will raise the AfterInsert event.
    Word.XMLNode node1 = this.SampleInsertNodes.Add("MemoFrom",
        this.SampleNode.NamespaceURI, ref range1);
}

void SampleInsertNodes_AfterInsert(object sender,
    Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs e)
{
    if (e.InUndoRedo)
    {
        MessageBox.Show("A child element of SampleInsertNodes was " +
            "inserted as a result of an undo or redo operation.");
    }
    else
    {
        MessageBox.Show("A child element of SampleInsertNodes " +
            "was inserted.");
    }
}

void SampleInsertNodes_BeforeDelete(object sender,
    Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs e)
{
    if (e.InUndoRedo)
    {
        MessageBox.Show("A child element of SampleInsertNodes " +
            "is about to be deleted as a result of an undo or " +
            "redo operation.");
    }
    else
    {
        MessageBox.Show("A child element of SampleInsertNodes " +
            "is about to be deleted.");
    }
