DocumentBase.XMLBeforeDelete Event

 

Occurs when a user deletes an XML element from a document. If more than one element is deleted from the document at the same time (for example, when cutting and pasting XML), the event is raised for each element that is deleted.

public event DocumentEvents2_XMLBeforeDeleteEventHandler XMLBeforeDelete

The following code example demonstrates event handlers for the XMLAfterInsert and XMLBeforeDelete events. The code displays a message before an XMLNode is deleted from the document and after an XMLNode is added to the document. To test this code example, use the XML Structure task pane to add XML elements to the document, and then experiment with the Undo Typing and Redo Typing options on the Edit menu. This example assumes that the current document is mapped to a valid XML schema. To use this example, run it from the ThisDocument class in a document-level project.

private void DocumentXMLBeforeAndAfterInsert()
{
    this.XMLAfterInsert +=
        new Word.DocumentEvents2_XMLAfterInsertEventHandler(
        ThisDocument_XMLAfterInsert);

    this.XMLBeforeDelete +=
        new Word.DocumentEvents2_XMLBeforeDeleteEventHandler(
        ThisDocument_XMLBeforeDelete);
}

void ThisDocument_XMLBeforeDelete(Word.Range DeletedRange,
    Word.XMLNode OldXMLNode, bool InUndoRedo)
{
    if (InUndoRedo)
    {
        MessageBox.Show(OldXMLNode.BaseName +
            " element is about to be deleted as a result" +
            " of an undo or redo operation.");
    }
    else

        MessageBox.Show(OldXMLNode.BaseName +
            " element is about to be deleted.");
