See my case is,

I am opening more than one `forms (toplevel=false)` inside a `panel`. All the `forms` opened inside that `panel` will be `dock filled` and `brought to front` during runtime. and my need in this situation is, how can i select the top most control(`form`) on that `panel`. Top most control means control(`form`) which is having greater `z-order`.

I am currently using this code by assumption,

```
 panel.controls(0)

```

Can any body tell me, whether the above snippet is right or any alternate syntax available in dot net to achieve that.?
