Question

I need to draw a dashed rectangle on selection of items in an itemcontrol.I am looking for a way to draw a rectangle by DrawingContext .We have got DrawingContext.DrawRectangle and DawingContext.DrawRoundedRectangle .But How can we give the properties like Stroke and StrokeDashArray of the Rectangle

Answer 1

When you call DrawingContext.DrawRectangle you should specify the Pen pen parameter which is used to draw stroke. So you can create the Pen instance and set the Pen.DashStyle property.
