Let's say I have
<TextBox
x:Name="txtBox1" />
<!-- more XAML here -->
<TextBox
x:Name="associatedToTextBox1"
IsEnabled={Binding ElementName=txtBox1, Path=Text, Magic=txtBox.Text != string.Empty} />
I want associatedToTextBox1
to be enabled only when txtBox1
is not empty. I thought there was a way to embed that functionality into xaml, without converters. Is this possible? If so, how?

There is nothing like an "inline expression".
You may however use a DataTrigger in a TextBox Style:
<TextBox x:Name="associatedToTextBox1">
<TextBox.Style>
<Style TargetType="TextBox">
<Style.Triggers>
<DataTrigger Binding="{Binding Text, ElementName=txtBox1}"
Value="">
<Setter Property="IsEnabled" Value="False"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
