The first thing that I wanted to do was to split the screen, but I wanted a diagonal split; similar to this: First, split the screen into three rows or columns which depends on how you want the orientation: Next, draw a transparent rectangle across the middle grid square: Share this: Leave a Reply Cancel reply Your email address will not be published.

Sorry, your blog cannot share posts by email. This topic covers mainly the Shape classes. Path is interesting because it can define an arbitrary geometry, and the Geometry class is involved here because that's one way to define the parts of a Path.

For a Shape to render to the app canvas, you must associate a Brush with it. Set the Fill property of the Shape to the Brush you want. For more info about brushes, see Using brushes. A Shape can also have a Stroke , which is a line that is drawn around the shape's perimeter.

A Stroke also requires a Brush that defines its appearance, and should have a non-zero value for StrokeThickness. StrokeThickness is a property that defines the perimeter's thickness around the shape edge. If you don't specify a Brush value for Stroke , or if you set StrokeThickness to 0, then the border around the shape is not drawn. An Ellipse is a shape with a curved perimeter. Here's the rendered Ellipse. In this case the Ellipse is what most people would consider a circle, but that's how you declare a circle shape in XAML: When an Ellipse is positioned in a UI layout, its size is assumed to be the same as a rectangle with that Width and Height ; the area outside the perimeter does not have rendering but still is part of its layout slot size.

A set of 6 Ellipse elements are part of the control template for the ProgressRing control, and 2 concentric Ellipse elements are part of a RadioButton. A Rectangle is a four-sided shape with its opposite sides being equal.

To create a basic Rectangle , specify a Width , a Height , and a Fill. You can round the corners of a Rectangle. To create rounded corners, specify a value for the RadiusX and RadiusY properties. These properties specify the x-axis and y-axis of an ellipse that defines the curve of the corners.

The maximum allowed value of RadiusX is the Width divided by two and the maximum allowed value of RadiusY is the Height divided by two. The next example creates a Rectangle with a Width of and a Height of We set the StrokeThickness to 3. We set the RadiusX property to 50 and the RadiusY property to 10, which gives the Rectangle rounded corners. Here's the rendered Rectangle. If your intention is to create a rectangle shape around other content, it might be better to use Border because it can have child content and will automatically size around that content, rather than using the fixed dimensions for height and width like Rectangle does.

A Border also has the option of having rounded corners if you set the CornerRadius property. On the other hand, a Rectangle is probably a better choice for control composition. A Rectangle shape is seen in many control templates because it's used as a "FocusVisual" part for focusable controls. Whenever the control is in a "Focused" visual state, this rectangle is made visible, in other states it's hidden.

A Polygon is a shape with a boundary defined by an arbitrary number of points. The boundary is created by connecting a line from one point to the next, with the last point connected to the first point. The Points property defines the collection of points that make up the boundary. In XAML, you define the points with a comma-separated list. In code-behind you use a PointCollection to define the points and you add each individual point as a Point value to the collection.

You don't need to explicitly declare the points such that the start point and end point are both specified as the same Point value.

How to Draw a Diagonal Line Using Only XAML (and no path data)

The rendering logic for a Polygon assumes that you are defining a closed shape and will connect the end point to the start point implicitly. The next example creates a Polygon with 4 points set to 10, , 60, , , , and , Here's the rendered Polygon. For example, a Point is part of the event data for touch events, so you can know exactly where in a coordinate space the touch action occurred. A Line is simply a line drawn between two points in coordinate space.

A Line ignores any value provided for Fill , because it has no interior space. For a Line , make sure to specify values for the Stroke and StrokeThickness properties, because otherwise the Line won't render. This enables minimal markup for horizontal or vertical lines. You could then use a TranslateTransform to move the entire Line , if you wanted it to start at a point other than 0,0.

A Polyline is similar to a Polygon in that the boundary of the shape is defined by a set of points, except the last point in a Polyline is not connected to the first point. If you specify a Fill of a Polyline , the Fill paints the interior space of the shape, even if the start point and end point of the Points set for the Polyline do not intersect. If you do not specify a Fill , then the Polyline is similar to what would have rendered if you had specified several individual Line elements where the start points and end points of consecutive lines intersected.

As with a Polygon , the Points property defines the collection of points that make up the boundary.

Fill and Stroke for shapes

In code-behind, you use a PointCollection to define the points and you add each individual point as a Point structure to the collection. This example creates a Polyline with four points set to 10, , 60, , , , and , A Stroke is defined but not a Fill. Here's the rendered Polyline. Notice that the first and last points are not connected by the Stroke outline as they are in a Polygon.

A Path is the most versatile Shape because you can use it to define an arbitrary geometry. But with this versatility comes complexity. You define the geometry of a path with the Data property. There are two techniques for setting Data:. This example shows a Path that might have resulted from using Blend for Visual Studio to produce just a few vector shapes and then saving the result as XAML.

The total Path consists of a Bezier curve segment and a line segment.

The example is mainly intended to give you some examples of what elements exist in the Path. Data serialization format and what the numbers represent. This Data begins with the move command, indicated by "M", which establishes an absolute start point for the path. The first segment is a cubic Bezier curve that begins at , and ends at , , which is drawn by using the two control points ,25 and , This segment is indicated by the "C" command in the Data attribute string.

The second segment begins with an absolute horizontal line command "H", which specifies a line drawn from the preceding subpath endpoint , to a new endpoint , Because it's a horizontal line command, the value specified is an x-coordinate.
