This code uses Tag of object lll to store the text:

<TextBox x:Name="lll">
    <TextBox.Style>
        <Style TargetType="{x:Type TextBox}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <TextBox Text="{Binding ElementName=lll , Path=Tag, Mode=OneWayToSource, UpdateSourceTrigger=PropertyChanged}"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </TextBox.Style>
</TextBox>
<Button Content="" Margin="25,40,-25,-40">
    <Button.Style>
        <Style TargetType="{x:Type Button}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <TextBlock Text="{Binding ElementName=lll, Mode=OneWay, Path=Tag}"/>
                    </ControlTemplate>
                </Setter.Value>
