Create a visual template for grid - wpf

Question

I am trying to create a visual template (saved in resource dictionary as xaml code) for a grid object, that I will apply to various grid objects created later in runtime.
I need a simple style with border and background.
What would be the best way of doing this?
Simple working examples would be greatly appreciated.
Ok, so, after searching for examples, I tried something like this:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="TestStyle">
<Setter Property="Background" Value="#FF873507" />
<Setter.Value>
<ControlTemplate>
<Grid>
<Border BorderThickness="7" CornerRadius="4">
<Border.BorderBrush>
<SolidColorBrush Color="#73B2F5"/>
</Border.BorderBrush>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Style>
</ResourceDictionary>

WPF doesn't really work like that... because the Grid class has no Template property, you cannot define a new ControlTemplate for it. The nearest thing that you can do is to create a UserControl with the UI elements that you want to use and then display the UserControl wherever you want to display those controls.
Alternatively, you could define your content inside a ControlTemplate if the inner controls will always be the same:
<ControlTemplate x:Key="StaticGrid">
<Grid>
<Border BorderThickness="7" CornerRadius="4">
<Border.BorderBrush>
<SolidColorBrush Color="#73B2F5"/>
</Border.BorderBrush>
<!--Add your inner elements here-->
</Border>
</Grid>
</ControlTemplate>
You could then display it like this:
<ContentControl Template="{StaticResource StaticGrid}" />
However, you wouldn't be able to add different inner elements using this method. If you used the UserControl method, you could potentially replace the word UserControl with Grid so that you were in fact extending the Grid class, but you still wouldn't be able to add different elements to it.
The best that you could do in a Style would be to set the Background property.

After more tries and frustrations, I found a much simpler solution, that worked for me.
Instead of trying to apply the style to the grid, I applied it to the border around the grid.
So, my dictionary looks like this:
<Style x:Key="TestStyle" TargetType="{x:Type Border}">
<Setter Property="Background" Value="#FFBDACA2" />
<Setter Property="BorderBrush" Value="#FFFF5E00" />
<Setter Property="CornerRadius" Value="30,30,30,30" />
<Setter Property="BorderThickness" Value="10" />
</Style>
And my main frame xaml:
<Border Style="{StaticResource TestStyle}" >
<Grid>
</Grid>
</Border>
