I created a WPF User Control similar I guess to the Android GridLayout.

It just automatically places a list of Controls into the next available cell... in a inner Grid control...

But what is so bad about this that it wasn't built into WPF in the first place? And is there actually a full implementation?

I Googled before writing this but don't think I found any existing ones.
