Working with Lists
This topic describes how to work programmatically with lists using Aspose.Words. Lists can be used in your documents to format, arrange, and emphasize text. Lists are a great way to organize data in documents, and they make it easier for readers to understand key points.
A list in a Microsoft Word document is a set of list formatting properties. Each list can have up to 9 levels and formatting properties, such as number style, start value, indent, tab position etc are defined separately for each level. A List object always belongs to the ListCollection collection.
Creating Lists by Applying List Formatting
Aspose.Words allows the easy creation of lists by applying list formatting. DocumentBuilder provides the DocumentBuilder.ListFormat property that returns a ListFormat object. This object has several methods to start and end a list and to increase/decrease the indent. There are two general types of lists in Microsoft Word: bulleted and numbered.
- To start a bulleted list, call ListFormat.ApplyBulletDefault .
- To start a numbered list, call ListFormat.ApplyNumberDefault .
The bullet or number and formatting are added to the current paragraph and all further paragraphs created using DocumentBuilder until ListFormat.RemoveNumbers is called to stop bulleted list formatting. In Word documents, lists may consist of up to nine levels. List formatting for each level specifies what bullet or number is used, left indent, space between the bullet and text etc.
- To increase the list level of the current paragraph by one level, call ListFormat.ListIndent.
- To decrease the list level of the current paragraph by one level, call ListFormat.ListOutdent.
The methods change the list level and apply the formatting properties of the new level.
The code example given below shows how to build a multilevel list.
How to Restart List for each Section
You can restart a list for each section using List.IsRestartAtEachSection property. Note that this option is supported only in RTF, DOC and DOCX document formats. This option will be written to DOCX only if OoxmlCompliance is higher then Ecma376. The following code example shows how to create a list and restart it for each section.
