DocumentModel is a central class in GemBox.Document component. It is an in-memory representation of a document file.

Document content can be retrieved through Sections property. For more information, see content model.

To load / read a document from a file or a stream, use static Load(String) methods. To preserve unsupported file format features, set PreserveUnsupportedFeatures to true. For more information, see preservation.

To save / write a document to a file or a stream use Save(String) methods. For more information, see supported file formats.

Methods

CalculateListItems()

Calculates the list items contained in this document.

public IEnumerable<ListItem> CalculateListItems()
Public Function CalculateListItems As IEnumerable(Of ListItem)
Returns
System.Collections.Generic.IEnumerable<ListItem>

A sequence of ListItems contained in this document.

Remarks

List (for example, ordered - with numbers, or unordered - with bullets) appearance in GemBox.Document is defined through ListFormat class that is set on Paragraph's ListFormat property or ParagraphStyle's ListFormat property.

ListFormat is different from other formats (ParagraphFormat and CharacterFormat) because it doesn't directly contain any formatting properties.

It contains a reference to a ListStyle which exposes ListLevelFormats for every list (indentation) level through its ListLevelFormats property.

ListLevelFormats contain direct formatting properties that affect the appearance of the list. Every ListStyle contains exactly 9 ListLevelFormats, one for each possible list (indentation) level.

Paragraph's list (indentation) level can be adjusted with ListLevelNumber property. Paragraph's list-related formatting will then be collected from the ListLevelFormat instance contained in the ListLevelFormats at the position ListLevelNumber. This ListLevelFormat can also be retrieved from the ListLevelFormat property.

ListLevelFormat retrieved from the ListLevelFormat property can be additionally modified to enable overriding property values of ListLevelFormat instance contained in the ListLevelFormats at the position ListLevelNumber on a Paragraph or ParagraphStyle basis.

To create a list in a document, first ListStyle instance has to be created from one of the predefined list style types specified with ListTemplateType enumeration. After that, ListFormat can be created with a specified ListStyle and assigned to a Paragraph's ListFormat property. For a complete example, see Lists example.

If ListStyle is not referenced from anywhere in the document (from any Paragraph or ParagraphStyle, then it won't be saved to a Word Document (DOCX) file, unless it is added to Styles collection.

Paragraph's list content, which prefixes paragraph content, is represented by ListItem type.

ListItems are not permanently stored in model nor they are written to file formats which fully support ListFormat, instead they are recreated each time CalculateListItems() method is called.

If document content or formatting is changed, then CalculateListItems() method should be called again to retrieve the latest list items.

For convenience, after calling CalculateListItems() method, ListItem can also be retrieved from ListItem property.

After calling System.IDisposable.Dispose() on System.Collections.Generic.IEnumerator<T> instance retrieved by calling System.Collections.Generic.IEnumerable<T>.GetEnumerator() on instance returned from CalculateListItems() method, paragraph's ListItem property will be null even if paragraph's IsList is true. This enables easy iteration over ListItems returned from CalculateListItems() method by using foreach statement and removing all references to ListItems after the iteration is finished.

Public Sub Save(httpResponse As Object, fileName As String)
Parameters
httpResponse
System.Object

Remarks
note

Supported only if updating the whole page with a postback and not if doing partial-page updates (when you use UpdatePanel controls to update selected regions of a page).

This method accepts System.Object rather than HttpResponse, HttpResponseBase or HttpResponseMessage because otherwise GemBox.Document assembly would have a dependency on System.Web or System.Net.Http assemblies and could not be used in applications which target Client Profile .NET Framework.

HttpResponse can be retrieved through the Response property of the HttpApplication, HttpContext, Page or UserControl classes.

For supported file extensions, see remarks for Save(String) method.
