How to call a Usercontrol from another in same window in WPF ? - wpf

Question

I have two UserControls in my project's MainWindow. In MainWindow I call the first UserControl whose content is a Button and put this FirstControl in a Grid. How can I call the second UserControl when I click on the button in FirstUserControl in MainWindow?
First UserControl :
<UserControl x:Class="BenashManage.UserControl.ButtonUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
Height="auto" Width="auto" RenderTransformOrigin="0,0">
<Grid>
<Border x:Name="BorderAddEdit" BorderBrush="{DynamicResource BorderBrush}" BorderThickness="5,5,5,5" CornerRadius="9,9,9,9" Background="{x:Null}">
<Grid Margin="0.2,0.2,5.4,4.2">
<Grid.RowDefinitions>
<RowDefinition Height="3*"/>
</Grid.RowDefinitions>
<Button Content="one" TextBlock.Foreground="White" Grid.Row="1" Margin="9,9,9,9" Height="28" TextBlock.FontSize="15" Name="btn_MartyMang" Click="click_Marty"/>
</Grid>
</Border>
</Grid>
</UserControl>
Second UserControl:
<UserControl x:Class="BenashManage.UserControl.InjuredUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Height="auto" Width="auto"
mc:Ignorable="d" RenderTransformOrigin="0,0" FontFamily="Arial" FontSize="14" TextBlock.Foreground="White">
<Grid VerticalAlignment="Top" Height="auto" Width="360" HorizontalAlignment="Right">
<Border x:Name="BorderAddEdit" Margin="6,2,6,6" BorderThickness="5,5,5,5" CornerRadius="9,9,9,9" Background="{x:Null}">
<Grid VerticalAlignment="Center" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto" MinHeight="20.8"/>
</Grid.ColumnDefinitions>
<TextBlock TextWrapping="Wrap" Text=":jjj" Grid.Column="1" Grid.Row="0" VerticalAlignment="Center" HorizontalAlignment="Right" Margin="0,4,-0.4,3"/>
<TextBox Grid.Row="6" TextAlignment="Right" VerticalAlignment="Center" Margin="3,2.8,2.2,2.2" />
</Grid>
</Border>
</Grid>
</UserControl>
MainWindow:
<Window x:Class="BenashManage.MartyrManage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Window.CommandBindings>
<CommandBinding Command="Close"
Executed="CloseCommand_Executed"/>
</Window.CommandBindings>
<Grid >
<Grid Margin="179,10,10.4,10" HorizontalAlignment="Center" VerticalAlignment="Center"
*******
Height="456" Width="357" Name="MoveToUserControl" ></Grid>
<Grid Margin="10,71,372.4,67" HorizontalAlignment="Center" VerticalAlignment="Center" Height="338" Width="auto" Name="ButtonManage" >
<controls:FirstUserControl Margin="0,0,0,92">
</controls:FirstUserControl>
</Grid>
</Grid>
</Window>

There are a couple of ways you can do this:
1) Get the parent of the UserControl and then get its children.
(((control1).Parent as Panel).Children[1] as UserControl)
2) Raise an event in the one UserControl which is handled by MainWindow to call the function in the other UserControl.
