Methods

Method	Description
get_DisplayResult()	Gets the text that represents the displayed field result.
get_End() const	Gets the node that represents the field end.
get_FieldEnd() const	Gets the node that represents the field end.
get_FieldStart() const	Gets the node that represents the start of the field.
get_Format()	Gets a FieldFormat object that provides typed access to field’s formatting.
get_HasListName()	Returns a value indicating whether the name of an abstract numbering definition is provided by the field’s code.
get_IsDirty()	Gets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
get_IsLocked()	Gets or sets whether the field is locked (should not recalculate its result).
get_ListLevel()	Gets or sets the level in the list, overriding the default behavior of the field.
get_ListName()	Gets or sets the name of the abstract numbering definition used for the numbering.
get_LocaleId()	Gets or sets the LCID of the field.
get_Result()	Gets or sets text that is between the field separator and field end.
get_Separator()	Gets the node that represents the field separator. Can be null.
get_Start() const	Gets the node that represents the start of the field.
get_StartingNumber()	Gets or sets the starting value for this field.
virtual get_Type() const	Gets the Microsoft Word field type.
GetFieldCode()	Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.
GetFieldCode(bool)	Returns text between field start and field separator (or field end if there is no separator).
GetType() const override
Is(const System::TypeInfo&) const override
Remove()	Removes the field from the document. Returns a node right after the field. If the field’s end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null.
set_IsDirty(bool)	Sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
set_IsLocked(bool)	Setter for Aspose::Words::Fields::Field::get_IsLocked.
set_ListLevel(const System::String&)	Setter for Aspose::Words::Fields::FieldListNum::get_ListLevel.
set_ListName(const System::String&)	Setter for Aspose::Words::Fields::FieldListNum::get_ListName.
set_LocaleId(int32_t)	Setter for Aspose::Words::Fields::Field::get_LocaleId.
set_Result(const System::String&)	Setter for Aspose::Words::Fields::Field::get_Result.
set_StartingNumber(const System::String&)	Setter for Aspose::Words::Fields::FieldListNum::get_StartingNumber.
static Type()
Unlink()	Performs the field unlink.
Update()	Performs the field update. Throws if the field is being updated already.
Update(bool)	Performs a field update. Throws if the field is being updated already.

Examples

Shows how to number paragraphs with LISTNUM fields.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

// LISTNUM fields display a number that increments at each LISTNUM field.
// These fields also have a variety of options that allow us to use them to emulate numbered lists.
auto field = System::ExplicitCast<FieldListNum>(builder->InsertField(FieldType::FieldListNum, true));

// Lists start counting at 1 by default, but we can set this number to a different value, such as 0.
// This field will display "0)".
field->set_StartingNumber(u"0");
builder->Writeln(u"Paragraph 1");

ASSERT_EQ(u" LISTNUM  \\s 0", field->GetFieldCode());

// LISTNUM fields maintain separate counts for each list level.
// Inserting a LISTNUM field in the same paragraph as another LISTNUM field
// increases the list level instead of the count.
// The next field will continue the count we started above and display a value of "1" at list level 1.
builder->InsertField(FieldType::FieldListNum, true);

// This field will start a count at list level 2. It will display a value of "1".
builder->InsertField(FieldType::FieldListNum, true);

// This field will start a count at list level 3. It will display a value of "1".
// Different list levels have different formatting,
// so these fields combined will display a value of "1)a)i)".
builder->InsertField(FieldType::FieldListNum, true);
builder->Writeln(u"Paragraph 2");

// The next LISTNUM field that we insert will continue the count at the list level
// that the previous LISTNUM field was on.
// We can use the "ListLevel" property to jump to a different list level.
// If this LISTNUM field stayed on list level 3, it would display "ii)",
// but, since we have moved it to list level 2, it carries on the count at that level and displays "b)".
field = System::ExplicitCast<FieldListNum>(builder->InsertField(FieldType::FieldListNum, true));
field->set_ListLevel(u"2");
builder->Writeln(u"Paragraph 3");

ASSERT_EQ(u" LISTNUM  \\l 2", field->GetFieldCode());

// We can set the ListName property to get the field to emulate a different AUTONUM field type.
// "NumberDefault" emulates AUTONUM, "OutlineDefault" emulates AUTONUMOUT,
// and "LegalDefault" emulates AUTONUMLGL fields.
// The "OutlineDefault" list name with 1 as the starting number will result in displaying "I.".
field = System::ExplicitCast<FieldListNum>(builder->InsertField(FieldType::FieldListNum, true));
field->set_StartingNumber(u"1");
field->set_ListName(u"OutlineDefault");
builder->Writeln(u"Paragraph 4");

ASSERT_TRUE(field->get_HasListName());
ASSERT_EQ(u" LISTNUM  OutlineDefault \\s 1", field->GetFieldCode());

// The ListName does not carry over from the previous field, so we will need to set it for each new field.
// This field continues the count with the different list name and displays "II.".
field = System::ExplicitCast<FieldListNum>(builder->InsertField(FieldType::FieldListNum, true));
field->set_ListName(u"OutlineDefault");
builder->Writeln(u"Paragraph 5");

doc->UpdateFields();
doc->Save(ArtifactsDir + u"Field.LISTNUM.docx");
