Copy bullet list number in new document?

Question

I have a node importer which goes like this

Dim nodeImporter As New Aspose.Words.NodeImporter(_wordDocument, documentComponentDocument,
 Aspose.Words.ImportFormatMode.UseDestinationStyles)

I am using it to copy childnode from one document to other. My child node is a bullet list.

documentComponentSection.Body.AppendChild(nodeImporter.ImportNode(childNode, True))

But my problem is that some properties of childnode like ListLabel i.e. bullet list numbering is not getting copied

As per your answer I tried following. But it is not working when I am creating new document for each node.

Aspose.Words.Document srcDoc = new Aspose.Words.Document(Mydir + "input.docx");

            Aspose.Words.Document dstDoc = new Aspose.Words.Document();
            var ctr = 0;
            int listid = 0;
            Aspose.Words.Lists.List dstList = null;
            foreach (Aspose.Words.Paragraph paragraph in srcDoc.GetChildNodes(Aspose.Words.NodeType.Paragraph, true))
            {
                Aspose.Words.NodeImporter imp = new Aspose.Words.NodeImporter(srcDoc, dstDoc, Aspose.Words.ImportFormatMode.KeepSourceFormatting);
                Aspose.Words.Node impNode = imp.ImportNode(paragraph, true);
                if (((Aspose.Words.Paragraph)impNode).IsListItem)
                {
                    ((Aspose.Words.Paragraph)impNode).ListFormat.ListLevel.StartAt = paragraph.ListFormat.List.ListId;
                    if (listid != paragraph.ListFormat.List.ListId)
                    {
                        listid = paragraph.ListFormat.List.ListId;
                        dstList = dstDoc.Lists.AddCopy(paragraph.ListFormat.List);
                    }


                    ((Aspose.Words.Paragraph)impNode).ListFormat.List = dstList;
                }
                dstDoc.FirstSection.Body.RemoveAllChildren();
                dstDoc.FirstSection.Body.AppendChild(impNode);
                var index = ctr++;
                dstDoc.Save(MyDir + index.ToString() + ".docx");
            }

Each output doc contains list index as 1.

Following code example imports the list item from source document into new empty document and keep the list label (numbered) value.

Aspose.Words.Document srcDoc = new Aspose.Words.Document(MyDir  + "input.docx");
DocumentBuilder builder = new DocumentBuilder(srcDoc);
srcDoc.UpdateListLabels();

Aspose.Words.Document dstDoc = new Aspose.Words.Document();
int ctr = 0;
Aspose.Words.NodeImporter imp = new Aspose.Words.NodeImporter(srcDoc, dstDoc, Aspose.Words.ImportFormatMode.KeepSourceFormatting);

foreach (Aspose.Words.Paragraph paragraph in srcDoc.GetChildNodes(Aspose.Words.NodeType.Paragraph, true))
{
    if (paragraph.IsListItem)
    {
        ListLabel label = paragraph.ListLabel;
        builder.MoveTo(paragraph);
        builder.StartBookmark("bookmark_" + label.LabelValue);
        builder.EndBookmark("bookmark_" + label.LabelValue);

        Aspose.Words.Node impNode = imp.ImportNode(paragraph, true);

        dstDoc.FirstSection.Body.RemoveAllChildren();
        dstDoc.FirstSection.Body.AppendChild(impNode);

        foreach (Bookmark bookmark in ((Aspose.Words.Paragraph)impNode).Range.Bookmarks)
        {
            if (!bookmark.Name.StartsWith("bookmark_"))
                continue;

            String listLabel = bookmark.Name.Replace("bookmark_", "");

            try
            {
                ((Aspose.Words.Paragraph)impNode).ListFormat.ListLevel.StartAt = Convert.ToInt32(listLabel);
                break;
            }
            catch (Exception ex)
            {
            }
        }

        ctr++;
        dstDoc.Range.Bookmarks.Clear();
        dstDoc.Save(MyDir + ctr.ToString() + ".docx");
    }
}

If the problem still remains, please report the issue in Aspose.Words forum with input and expected output documents.
