Programatically adding a WPF control

I'm a newbie at using WPF. I have a project that is a GUI that has a number of tabs displaying information in different ways. One of my tabs I want to be a sort of "google earth" type view. Where I can zoom and pan, etc.

After reading around a bit, I decided to use WPF to accomplish this.

So, I took my windows Form, which has a tab control with tab pages. On one of the tab pages, I added a xaml user control via the element host. So, I guess what I have, as I understand it, is a xaml control, added to a tab page control, via an element host.

Now, my xaml user control, right now, is super simple, just a hello world button. I know I eventually want to add more buttons and other controls on the fly (programatically). So I am just trying to do a simple test where I progrmatically add another button to my xaml user control.

I don't know how to do this in code. Am I adding it to the xaml user control, if so, how? Am I adding it to the element host? The tab page?? I'm not really sure how to begin.

Thanks!

Sawiner,

thanks for the info! I realized my mistake later. When I created the user control xaml, VS2008 didn't name the canvas by default. So when i tried to access it in the c# project, I couldn't get to it. Once I named it (Name = "myName") in the XAML tag, I was of course able to get to it and its methods (like, Children.Add(newBtn)).

I also wanted to place the button strategically, so in case anyone is interested, here is a code snipped on how to place the button in a certain location on the canvas...

newBtn.SetValue(System.Windows.Controls.Canvas.LeftProperty, (double)100);
newBtn.SetValue(System.Windows.Controls.Canvas.TopProperty, (double)100);

Thanks! Btw, I have another WPF question I'll post soon. So look out for it! :)
