Add WPF control at runtime - wpf

Question

I've written a WPF UserControl, and want to add one or more of it to my Window at runtime when I click a button. How can I do that?
Edit: Further specification
I want to add the usercontrols to a Canvas, and put in a absolute position. The canvas is a drawing of the floors in my house, and each usercontrol has properties to indicate where in the house it is positioned. So I want all the controls to be positioned in the correct position on the canvas.
I'm thinking something like this
var light = new LightUserControl(2);
HouseCanvas.Children.Add(light); // this should be positioned in a specific place

Answer 1

After you add the your control to the Canvas you need to specify the top and left co-ordinates using the Canvas.Top and Canvas.Left attached properties as follows.
var light = new LightUserControl(2);
HouseCanvas.Children.Add(light);
Canvas.SetLeft(light, 20);
Canvas.SetTop(light, 20);

Answer 2

In case you want to add the control to a Grid instead of a Canvas you can specify all the Grid properties through the Grid static class as follows:
Label newLabel = new Label();
newLabel.Content = "The New Element";
Main.Children.Add(newLabel);
Grid.SetColumn(newLabel, 0);
Grid.SetRow(newLabel, 0);

Answer 3

Add a StackPanel to the window and on each button click,
_stackPanel.Children.Add(new YourControl());
You can do this in many ways.

Answer 4

My solution:
for (i = 1; i <= buttoncount; i++)
{
Button mybutton = new Button();
Grid1.Children.Add(mybutton);
mybutton.Height = 100;
mybutton.Width = 100;
mybutton.Name = "button" + i;
mybutton.Content = mybutton.Name;
}

Answer 5

public static void AddChild(this Visual parent, UIElement child)
{
if (InternalAddChild(parent, child))
{
return;
}
throw new NotSupportedException();
}
private static bool InternalAddChild(Visual parent, UIElement child)
{
Panel panel = parent as Panel;
if (panel != null)
{
panel.Children.Add(child);
return true;
}
for (int i = VisualTreeHelper.GetChildrenCount(parent) - 1; i != -1; i--)
{
Visual target = VisualTreeHelper.GetChild(parent, i) as Visual;
if (target != null && InternalAddChild(target, child))
{
return true;
}
}
return false;
}

Answer 6

Just complementing the answer:
for (i = 1; i <= buttoncount; i++)
{
Button mybutton = new Button();
Grid1.Children.Add(mybutton);
mybutton.Height = 100;
mybutton.Width = 100;
mybutton.Name = "button" + i;
mybutton.Content = mybutton.Name;
mybutton.Click += button_Click;
}
private void button_Click(object sender, RoutedEventArgs e)
{
// do something
}
