Question

I am new at using path in a wpf and I do not know how to convert a segment of xaml code to C# code. Could someone help me with this? I cite following the xaml code and then my attempt to convert it. What the C# code lacks of? One more thing I ‘d like to ask is if a grid is enough so as a path to appear in the window.

<Path Stroke="Black" StrokeThickness="1">
<Path.Data>
<PathGeometry>
  <PathGeometry.Figures>
    <PathFigureCollection>
      <PathFigure StartPoint="10,100">
        <PathFigure.Segments>
          <PathSegmentCollection>
            <QuadraticBezierSegment Point1="200,200" Point2="300,100" />
          </PathSegmentCollection>
        </PathFigure.Segments>
      </PathFigure>
    </PathFigureCollection>
  </PathGeometry.Figures>
</PathGeometry>

My C# code:

Path myPath = new Path();
myPath.Stroke = Brushes.Black;
myPath.StrokeThickness = 1
PathGeometry myPathGeometry = new PathGeometry();
myPathGeometry.Figures = new PathFigureCollection();

PathFigure myPathFigure = new PathFigure();
myPathFigure.StartPoint = new Point(10, 100);
myPathFigure.Segments = new PathSegmentCollection();
QuadraticBezierSegment theSegment = new QuadraticBezierSegment();
theSegment.Point1 = new Point(200, 200);
theSegment.Point2 = new Point(100, 300);
myPathFigure.Segments.Add(theSegment);
myPathGeometry.Figures.Add(myPathFigure);

You have to add following line at the end,

myPath.Data = myPathGeometry;

And you should add x:Name to your <Grid> as <Grid x:Name='myGrid'>

And add one more line,

myGrid.Children.Add(myPath);
