Answer 1

You can try Element binding inside the user control. Just give a name to UserControl and bind property:

<UserControl x:Class="controlmaker.checkButton"
         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" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="114" d:DesignWidth="221"
         x:Name="MyUserControl">
<Grid Background="Aqua" >
    <CheckBox Content="CheckBox" Height="16" HorizontalAlignment="Left"
          Margin="58,24,0,0" Name="checkBox1" VerticalAlignment="Top" />
    <Button Content="{Binding Path=buttText, ElementName=MyUserControl}"
          Height="23" HorizontalAlignment="Left" Margin="58,57,0,0" 
          Name="button1" VerticalAlignment="Top" Width="75" />
</Grid>
</UserControl>

And then you can Bind or put static text from user control usage place

<my:checkButton buttText="aka" />

or

  <my:checkButton buttText="{Binding SomeProperty}" />
