XAML Values
Property Value
Type: System::DoubleThe minimum desired column width, in device independent pixels. A value of Double::NaN causes only one column to be displayed, regardless of the page width. The default is Double::NaN.
A FlowDocument dynamically adjusts its contents to maximize content presentation within the available display space. The number of visible columns is determined by the number of columns that can fit in available display space, given the minimum column width specified by this property. The actual column width may be greater than the value specified by this property.
Changing the size of the window in either direction will result in columns being dynamically regenerated to make the best use of space. In this way, the content dynamically adapts to the user's environment.
The following example shows how to set the ColumnWidth attribute of a FlowDocument element.
<FlowDocumentReader> <FlowDocument ColumnWidth="140.0"> <Paragraph> Columns of content within a page in this FlowDocument will be at least 140 pixels wide. </Paragraph> </FlowDocument> </FlowDocumentReader>
The following example shows how to set the ColumnWidth property programmatically.
