Examples

The following example shows how to set the ColumnRuleWidth property programmatically.

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));
// Set a column rule two pixels wide colored Dodger blue.
flowDoc.ColumnRuleWidth = 2.0;
flowDoc.ColumnRuleBrush = Brushes.DodgerBlue;

Dim flowDocColRule As New FlowDocument(New Paragraph(New Run("A bit of text content...")))
    ' Set a column rule two pixels wide colored Dodger blue.
flowDocColRule.ColumnRuleWidth = 2.0
flowDocColRule.ColumnRuleBrush = Brushes.DodgerBlue

Remarks

The column rule is a line that is drawn between columns, and is used to visually separate columns of content.

This property has no effect if the ColumnRuleBrush property is null.

Column rules are only displayed when there are two or more columns. The column rule width is constrained to be less than or equal to the ColumnGap.
