MailMergeCleanupOptions

MailMergeCleanupOptions enumeration

Specifies options that determine what items are removed during mail merge.

[Flags]
public enum MailMergeCleanupOptions

Values

Name	Value	Description
None	0	Specifies a default value.
RemoveEmptyParagraphs	1	Specifies whether paragraphs that contained mail merge fields with no data should be removed from the document. When this option is set, paragraphs which contain region start and end merge fields which are otherwise empty are also removed.
RemoveUnusedRegions	2	Specifies whether unused mail merge regions should be removed from the document.
RemoveUnusedFields	4	Specifies whether unused merge fields should be removed from the document.
RemoveContainingFields	8	Specifies whether fields that contain merge fields (for example, IFs) should be removed from the document if the nested merge fields are removed.
RemoveStaticFields	10	Specifies whether static fields should be removed from the document. Static fields are fields, which results remain the same upon any document change. Fields, which do not store their results in a document and are calculated on the fly (like FieldListNum, FieldSymbol, etc.) are not considered to be static.
RemoveEmptyTableRows	20	Specifies whether empty rows that contain mail merge regions should be removed from the document.

Examples

Shows how to remove empty paragraphs that a mail merge may create from the merge output document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.InsertField(" MERGEFIELD TableStart:MyTable");
builder.InsertField(" MERGEFIELD FirstName ");
builder.Write(" ");
builder.InsertField(" MERGEFIELD LastName ");
builder.InsertField(" MERGEFIELD TableEnd:MyTable");

DataTable dataTable = new DataTable("MyTable");
dataTable.Columns.Add("FirstName");
dataTable.Columns.Add("LastName");
dataTable.Rows.Add(new object[] { "John", "Doe" });
dataTable.Rows.Add(new object[] { "", "" });
dataTable.Rows.Add(new object[] { "Jane", "Doe" });

doc.MailMerge.CleanupOptions = mailMergeCleanupOptions;
doc.MailMerge.ExecuteWithRegions(dataTable);

if (doc.MailMerge.CleanupOptions == MailMergeCleanupOptions.RemoveEmptyParagraphs) 
    Assert.AreEqual(
        "John Doe\r" +
        "Jane Doe", doc.GetText().Trim());
else
    Assert.AreEqual(
        "John Doe\r" +
        " \r" +
        "Jane Doe", doc.GetText().Trim());

Shows how to automatically remove MERGEFIELDs that go unused during mail merge.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create a document with MERGEFIELDs for three columns of a mail merge data source table,
// and then create a table with only two columns whose names match our MERGEFIELDs.
builder.InsertField(" MERGEFIELD FirstName ");
builder.Write(" ");
builder.InsertField(" MERGEFIELD LastName ");
builder.InsertParagraph();
builder.InsertField(" MERGEFIELD City ");

DataTable dataTable = new DataTable("MyTable");
dataTable.Columns.Add("FirstName");
dataTable.Columns.Add("LastName");
dataTable.Rows.Add(new object[] { "John", "Doe" });
dataTable.Rows.Add(new object[] { "Joe", "Bloggs" });

// Our third MERGEFIELD references a "City" column, which does not exist in our data source.
// The mail merge will leave fields such as this intact in their pre-merge state.
// Setting the "CleanupOptions" property to "RemoveUnusedFields" will remove any MERGEFIELDs
// that go unused during a mail merge to clean up the merge documents.
doc.MailMerge.CleanupOptions = mailMergeCleanupOptions;
doc.MailMerge.Execute(dataTable);

if (mailMergeCleanupOptions == MailMergeCleanupOptions.RemoveUnusedFields || 
    mailMergeCleanupOptions == MailMergeCleanupOptions.RemoveStaticFields)
    Assert.AreEqual(0, doc.Range.Fields.Count);
else
    Assert.AreEqual(2, doc.Range.Fields.Count);
