flowdocument

问题 I have the need to generate dynamically generate a FlowDocument from a large set of data. Because the process takes several minutes, I'd like to perform the operation on a background thread rather than have the UI hang. However, I can't generate the FlowDocument on a non-UI thread otherwise attempts to insert rectangles and images cause run-time errors complaining that it's not STA thread. There are a couple of threads on StackOverflow which seem to involve the same problem I'm having:

问题 I've got a FlowDocument which has some elements like so: <InlineUIContainer> <Button Click="Button_Click" Tag="123456789890"> <Image Source="Images\Image1.png" /> </Button> </InlineUIContainer> This is stored off in a .xaml file and gets loaded at some point by doing something like so: flowDocument = XamlReader.Load(xamlFile, parserContext) as FlowDocument; flowDocumentReader.Document = flowDocument; The loading fails with the following error: XamlParseException - Failed to create a 'Click'

问题 I use DocumentPaginator to divide FlowDocument's text into pages. Is it possible to get content of each pages by page number after ComputePageCount()? If not, how can I do it in other way? Code: var flowDocument = this.Document; flowDocument.MaxPageHeight = this.MaxContentHeight; DocumentPaginator paginator = ((IDocumentPaginatorSource)flowDocument).DocumentPaginator; paginator.ComputePageCount(); 回答1: Yes, it is possible.

问题 Studies have shown this is the way to prevent wrapping in, say, a Paragraph: <Paragraph> <TextBlock TextWrapping="NoWrap">unwrapping text</TextBlock> </Paragraph> How can I get the behavior in C# code? new Paragraph(new TextBlock() { Text = "unwrapping text", TextWrapping = TextWrapping.NoWrap }); Yields cannot convert from 'System.Windows.Controls.TextBlock' to 'System.Windows.Documents.Inline' because Paragraph's constructor is expecting an Inline.
