Any help with this would be much appreciated.

I am trying to build an app in Windows 8 using xaml and vb.

To test the process of adding a path dynamically to the UI I have created a class that draws a circle using a path (code below). The code fires when a button is tapped/clicked.

The circle then appears briefly near the centre of the screen but then disappears.

If I then count the children on the grid, the circle is counted. Its just not visible.

I’d like to understand what is happening and stop the circle from disappearing.

Dim path As New Windows.UI.Xaml.Shapes.Path
Dim rectG As New EllipseGeometry
rectG.Center = New Point(500, 500)
rectG.RadiusX = 100
rectG.RadiusY = 100
path.Data = rectG
path.Stroke = New SolidColorBrush(Windows.UI.Colors.LightGreen)
path.StrokeThickness = 1
path.Fill = New SolidColorBrush(Windows.UI.Colors.LightGreen)
path.Name = "TestName"
_TargetGrid.Children.Add(path)

    Finally figured it out. I needed to set the column and row span property.

    On the test I did it using the code although in a proper app it would probably make sense to use some kind of predetermined styling.

    However, here is the code I added:

    path.SetValue(Grid.ColumnSpanProperty, 5)
path.SetValue(Grid.RowSpanProperty, 5)
