RemoveEmptyParagraphs for TableStart / TableEnd

Hi, Is it possible to have the RemoveEmptyParagraphs flag handle removing empty lines that contain nothing but a <<TableStart_MyRegion>> or <<TableEnd_MyRegion>>?
For other merge fields, will it support removing blank lines caused by NULL values as well as blanks?
Thanks.

Hi
Thanks for your inquiry. I think that you can use MergeField event handler to achieve this. For example see the following code and attached documents.

public void Test253()
{
    // Create some datasource
    DataTable myTable = new DataTable("myTable");
    myTable.Columns.Add("field1");
    myTable.Columns.Add("field2");
    myTable.Columns.Add("field3");
    for (int i = 0; i < 10; i++)
    {
        myTable.Rows.Add(new object[] { i.ToString(), "Some data" + i.ToString(), "Some text" + i.ToString() });
    }
    // perform mailmerge
    Document doc = new Document(@"Test253\in.doc");
    doc.MailMerge.MergeField += new MergeFieldEventHandler(MailMerge_MergeField_253);
    doc.MailMerge.ExecuteWithRegions(myTable);
    doc.Save(@"Test253\out.doc");
}
void MailMerge_MergeField_253(object sender, MergeFieldEventArgs e)
{
    if (e.FieldName == "field1")
    {
        Table parentTable = (e.Field.Start.GetAncestor(NodeType.Table) as Table);
        // Remove empty paragraphs before and after table
        parentTable.NextSibling.Remove();
        parentTable.PreviousSibling.Remove();
    }
}

Hope this helps.
Best regards.
