SequenceSeparator

FieldIndex.SequenceSeparator property

Gets or sets the character sequence that is used to separate sequence numbers and page numbers.

public string SequenceSeparator { get; set; }

Examples

Shows how to split a document into portions by combining INDEX and SEQ fields.

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

// Create an INDEX field which will display an entry for each XE field found in the document.
// Each entry will display the XE field's Text property value on the left side,
// and the number of the page that contains the XE field on the right.
// If the XE fields have the same value in their "Text" property,
// the INDEX field will group them into one entry.
FieldIndex index = (FieldIndex)builder.InsertField(FieldType.FieldIndex, true);

// In the SequenceName property, name a SEQ field sequence. Each entry of this INDEX field will now also display
// the number that the sequence count is on at the XE field location that created this entry.
index.SequenceName = "MySequence";

// Set text that will around the sequence and page numbers to explain their meaning to the user.
// An entry created with this configuration will display something like "MySequence at 1 on page 1" at its page number.
// PageNumberSeparator and SequenceSeparator cannot be longer than 15 characters.
index.PageNumberSeparator = "\tMySequence at ";
index.SequenceSeparator = " on page ";
Assert.IsTrue(index.HasSequenceName);

Assert.AreEqual(" INDEX  \\s MySequence \\e \"\tMySequence at \" \\d \" on page \"", index.GetFieldCode());

// SEQ fields display a count that increments at each SEQ field.
// These fields also maintain separate counts for each unique named sequence
// identified by the SEQ field's "SequenceIdentifier" property.
// Insert a SEQ field which moves the "MySequence" sequence to 1.
// This field no different from normal document text. It will not appear on an INDEX field's table of contents.
builder.InsertBreak(BreakType.PageBreak);
FieldSeq sequenceField = (FieldSeq)builder.InsertField(FieldType.FieldSequence, true);
sequenceField.SequenceIdentifier = "MySequence";

Assert.AreEqual(" SEQ  MySequence", sequenceField.GetFieldCode());

// Insert an XE field which will create an entry in the INDEX field.
// Since "MySequence" is at 1 and this XE field is on page 2, along with the custom separators we defined above,
// this field's INDEX entry will display "Cat" on the left side, and "MySequence at 1 on page 2" on the right.
FieldXE indexEntry = (FieldXE)builder.InsertField(FieldType.FieldIndexEntry, true);
indexEntry.Text = "Cat";

Assert.AreEqual(" XE  Cat", indexEntry.GetFieldCode());

// Insert a page break and use SEQ fields to advance "MySequence" to 3.
builder.InsertBreak(BreakType.PageBreak);
sequenceField = (FieldSeq)builder.InsertField(FieldType.FieldSequence, true);
sequenceField.SequenceIdentifier = "MySequence";
sequenceField = (FieldSeq)builder.InsertField(FieldType.FieldSequence, true);
sequenceField.SequenceIdentifier = "MySequence";

// Insert an XE field with the same Text property as the one above.
// The INDEX entry will group XE fields with matching values in the "Text" property
// into one entry as opposed to making an entry for each XE field.
// Since we are on page 2 with "MySequence" at 3, ", 3 on page 3" will be appended to the same INDEX entry as above.
// The page number portion of that INDEX entry will now display "MySequence at 1 on page 2, 3 on page 3".
indexEntry = (FieldXE)builder.InsertField(FieldType.FieldIndexEntry, true);
indexEntry.Text = "Cat";

// Insert an XE field with a new and unique Text property value.
// This will add a new entry, with MySequence at 3 on page 4.
builder.InsertBreak(BreakType.PageBreak);
indexEntry = (FieldXE)builder.InsertField(FieldType.FieldIndexEntry, true);
indexEntry.Text = "Dog";

doc.UpdatePageLayout();
doc.UpdateFields();
doc.Save(ArtifactsDir + "Field.INDEX.XE.Sequence.docx");
