Methods

MethodDescription
get_DisplayResult()Gets the text that represents the displayed field result.
get_End() constGets the node that represents the field end.
get_FieldEnd() constGets the node that represents the field end.
get_FieldStart() constGets the node that represents the start of the field.
get_Format()Gets a FieldFormat object that provides typed access to field’s formatting.
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_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() constGets the node that represents the start of the field.
virtual get_Type() constGets 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_LocaleId(int32_t)Setter for Aspose::Words::Fields::Field::get_LocaleId.
set_Result(const System::String&)Setter for Aspose::Words::Fields::Field::get_Result.
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 use NUMCHARS, NUMWORDS, NUMPAGES and PAGE fields to track the size of our documents.

auto doc = MakeObject<Document>(MyDir + u"Paragraphs.docx");
auto builder = MakeObject<DocumentBuilder>(doc);

builder->MoveToHeaderFooter(HeaderFooterType::FooterPrimary);
builder->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Center);

// Below are three types of fields that we can use to track the size of our documents.
// 1 -  Track the character count with a NUMCHARS field:
auto fieldNumChars = System::ExplicitCast<FieldNumChars>(builder->InsertField(FieldType::FieldNumChars, true));
builder->Writeln(u" characters");

// 2 -  Track the word count with a NUMWORDS field:
auto fieldNumWords = System::ExplicitCast<FieldNumWords>(builder->InsertField(FieldType::FieldNumWords, true));
builder->Writeln(u" words");

// 3 -  Use both PAGE and NUMPAGES fields to display what page the field is on,
// and the total number of pages in the document:
builder->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Right);
builder->Write(u"Page ");
auto fieldPage = System::ExplicitCast<FieldPage>(builder->InsertField(FieldType::FieldPage, true));
builder->Write(u" of ");
auto fieldNumPages = System::ExplicitCast<FieldNumPages>(builder->InsertField(FieldType::FieldNumPages, true));

ASSERT_EQ(u" NUMCHARS ", fieldNumChars->GetFieldCode());
ASSERT_EQ(u" NUMWORDS ", fieldNumWords->GetFieldCode());
ASSERT_EQ(u" NUMPAGES ", fieldNumPages->GetFieldCode());
ASSERT_EQ(u" PAGE ", fieldPage->GetFieldCode());

// These fields will not maintain accurate values in real time
// while we edit the document programmatically using Aspose.Words, or in Microsoft Word.
// We need to update them every we need to see an up-to-date value.
doc->UpdateFields();
doc->Save(ArtifactsDir + u"Field.NUMCHARS.NUMWORDS.NUMPAGES.PAGE.docx");
