<p>We are creating an XBAP application that we need to have rounded corners in various locations in a single page and we would like to have a WPF Rounded Corner container to place a bunch of other elements within.  Does anyone have some suggestions or sample code on how we can best accomplish this?   Either with styles on a  or with creating a custom control?</p>

You don't need a custom control, just put your container in a border element:
```
```
<Border BorderBrush="#FF000000" BorderThickness="1" CornerRadius="8">
   <Grid/>
</Border>
```
```
You can replace the
```
<Grid/>
```
with any of the layout containers...
