Arrange controls in circular/rectangular shape dynamically

Question

Just wondering if there is a way to arrange controls in a circular shape like a round table. Control can be an image or textbox. For example: if i have an ellipse shape, all am looking is to fill controls along the perimeter border of the ellipse. Please let me know if there is a way to do this using xaml and c#. Here is what i have done so far. I created a rectangle and have the X, Y position values using the Point Type. Based on the points i could create a textbox.. but couldn;t loop until the i reach 0,0 again. 0,0 is the bottom left position (x,y)

for (int i = 0; i < count; i++)
        {
            TextBox tb = new TextBox();
            tb.Text = "Button " + i;
            Point p = new Point();
            p.X =  (int)(Math.Cos((double)i) * radius) + radius;
            p.Y = (int)(Math.Sin((double)i) * radius) + radius;
            Canvas.SetLeft(tb, p.X);
            Canvas.SetTop(tb, p.Y);
            SpTable.Children.Add(tb);
        }

Similarly need to add controls in the Y direction... Ellipse can be replaced by Rectangle as well. The controls are adding but they are getting added in only one column just below one another.

You have to calculate the positions of the textboxes using cos and sin.

This creates 20 textboxes arranged in a circular pattern.

        int radius = 200;

        for (int i = 1; i < 20; i++)
        {
            TextBox tb = new TextBox();

            tb.Left = (int)(Math.Cos((double)i) * radius) + radius;
            tb.Top = (int)(Math.Sin((double)i) * radius) + radius;

            this.Controls.Add(tb);
        }

Hope this helps
