Open User Control in a grid in main Window - WPF - wpf

Question

I'm writing now an app with WPF and trying to remember things I did long time ago.
I'm trying to have a window with 4 buttons that I will navigate with them through the app.
My code:
<Grid>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="55*"/>
<ColumnDefinition Width="453*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StatusBar Margin="0" VerticalAlignment="Top" Height="23" Grid.ColumnSpan="4" Grid.Row="2" Background="#FF1A202C"/>
<Menu Margin="0" Height="23" Grid.ColumnSpan="4" Background="#FF1A202C" />
<StackPanel Grid.Row="1" Width="224.2" HorizontalAlignment="Left" Background="#FF1F7872" >
<Button Content="Dashboard" Style="{StaticResource BorderlessButton}" Foreground="#FFF1E7E7" Template="{DynamicResource GlassButton}" Margin="25,20,23,20" Click="Button_Click_1" />
<Button Content="Components" Style="{StaticResource BorderlessButton}" Foreground="#FFF1E7E7" Template="{DynamicResource GlassButton}" Margin="25,20,23,20"/>
<Button Content="TimeLine" Style="{StaticResource BorderlessButton}" Foreground="#FFF1E7E7" Template="{DynamicResource GlassButton}" Margin="25,20,23,20"/>
<Button Content="Drilldown" Style="{StaticResource BorderlessButton}" Foreground="#FFF1E7E7" Template="{DynamicResource GlassButton}" Margin="25,20,23,20"/>
</StackPanel>
<Grid Grid.Column="2" Grid.Row="1" HorizontalAlignment="Stretch" Grid.ColumnSpan="2" Background="#FF72B095">
</Grid>
</Grid>
I've 4 user controls that I want they will appear in the Grid (maybe I'll need to replace the control) when I'm clicking the buttons.
A friend suggest that I'll use storyboard on Blend, but I remembered that a long time ago I did it differently and I used only XAML and C#.
I tried to use the storyboard tool but I didn’t understand how to use it, in general I think the storyboard tool is overkill for my use.

Answer 1

Give a name to the grid:
<Grid Name="MainGrid" >
</Grid>
and then, in code behine, handle click events:
void Button_Click_1(object sender, MouseEventArgs e)
{
MainGrid.Children.Add( // Your control //);
}
