Restless Converters

This project provides an Html to Xaml converter and a custom paste handler that enables you to copy/paste (or drag/drop) information from a web site into the FlowDocument of a Rich Text Box.

The Html to Xaml converter does not attempt to completely replicate the incoming html. Instead, it enables you to specify (for instance) the appearance of an incoming H1 element, rather than copying the style used on the web site. Other tags may be similarly customized.

Usage

string html = GetHtml();
string xaml = HtmlToXamlConverter.Create().SetHtml(html).Convert();

You can also supply an optional ConverterOptions object

string html = GetHtml();
string xaml = HtmlToXamlConverter.Create(new ConverterOptions()
{
    AddDefaultBlockConfigs = false,
    IsOutputIndented = true
}) .SetHtml(html).Convert();

Converter Options

Converter options affect how the xaml is generated.

Property	Type	Default	Description
IsTopLevelFlowDocument	bool	false	When this property is true, the top level element of the output is a flow document. When false, the top level element is a section. If you're going to place the output into a RichTextBox, this property should be left at its default.
SectionConfig	BlockConfig	BlockConfig	Provides access to the configuration that is applied to Xaml Section nodes
AddDefaultBlockConfigs	bool	true	Determines whether default block configurations are applied. Defaults include settings for H1, H2, UL, OL, and others. You can change any defaults before conversion or supply your own, or both.
ProcessUnknown	bool	false	Determines whether unknown nodes are processed. When an unknown node is processed, it appears in the xaml with its name and inner text. Mostly a debugging aide.
SetPreserve	bool	false	Determines whether the xaml output has xml:space preserve added.
IsOutputIndented	bool	false	Determines whether xaml output is indented. When false, xaml is all on one long line. When true, the xaml is broken up into lines, indented, and easier to read.

Paste Handler

Paste handler provides a way to register controls for automatic custom paste handling.

PasteHandler.Register(MyRichTextBox);

When your RichTextBox is registered for automatic usage, you can copy/paste (or drag/drop) from a web site, and the conversion occurs behind the scenes

You can also register a TextBox for automatic usage, but this produces no difference unless you register it with the optional PasteHandlerOptions

PasteHandler.Register(MyTextBox, new PasteHandlerOptions(HtmlPasteAction.ConvertToText));

This enables the TextBox to receive the actual Html, not just the text as with the control's default behavior. Note that if you keep a reference to PasteHandler (the return value of the Register() method), you can change the paste handling behavior at run time.
