FlowDocument Constructor (Block)

 

Initializes a new instance of the FlowDocument class, adding a specified Block element as the initial content.

Namespace:   System.Windows.Documents
Assembly:  PresentationFramework (in PresentationFramework.dll)

Public Sub New (
	block As Block
)

Parameters

block
Type: System.Windows.Documents.Block

An object deriving from the abstract Block class, to be added as the initial content.

Exception Condition
ArgumentNullException

block is null.

Valid input types for block include BlockUIContainer, List, Paragraph, Section, and Table.

The following example demonstrates the use of this constructor. In this case, the FlowDocument contains a flow element block structure consisting of a text run nested in a paragraph.

Dim flowDocSimple As New FlowDocument(New Paragraph(New Run("A bit of text content...")))

The following example programmatically constructs a simple 2 x 2 table and then uses the FlowDocument constructor to create a new FlowDocument containing the table. Though a somewhat more complicated flow element block structure is used, use of the constructor is the same as in the preceding example.

' A paragraph with sample text will serve as table content.
Dim tableText As New Paragraph(New Run("A bit of text content..."))

Dim sampleTable As New Table()

' Create and add a couple of columns.
sampleTable.Columns.Add(New TableColumn())
sampleTable.Columns.Add(New TableColumn())

' Create and add a row group and a couple of rows.
sampleTable.RowGroups.Add(New TableRowGroup())
sampleTable.RowGroups(0).Rows.Add(New TableRow())
sampleTable.RowGroups(0).Rows.Add(New TableRow())

' Create four cells initialized with the sample text paragraph.
sampleTable.RowGroups(0).Rows(0).Cells.Add(New TableCell(tableText))
sampleTable.RowGroups(0).Rows(0).Cells.Add(New TableCell(tableText))
sampleTable.RowGroups(0).Rows(1).Cells.Add(New TableCell(tableText))
sampleTable.RowGroups(0).Rows(1).Cells.Add(New TableCell(tableText))

' Finally, use the FlowDocument constructor to create a new FlowDocument containing 
' the table constructed above.
        Dim flowDocTable As New FlowDocument(sampleTable)
