I have data templates that looks like: <DataTemplate> <TextBlock DataContext={Binding Fields[ABC]} Text={Binding}/> </DataTemplate> <DataTemplate>

I have data templates that looks like:

<DataTemplate>
 <TextBlock DataContext="{Binding Fields[ABC]}" Text="{Binding}"/>
</DataTemplate>

<DataTemplate>
 <TextBlock DataContext="{Binding Fields[)]}" Text="{Binding}"/>
</DataTemplate>

For a class that looks like

class Source {
  public Dictionary<string, string> Fields { get; private set; }
}

When applying the second template, with the ‘)’ key in the DataContext binding, I get a XamlParseException. Is there any way to allow Dictionary Binding to work with other strings such as ‘)’ ? Some sort of escape character sequence?

    You could construct a valid path by using path parameters, this makes sure the parenthesis is passed as a string and not part of the path description. The easiest way to do that would probably be via a custom markup extension as shown in this answer of mine.

    The binding then could be written as:

    {Binding Path={me:PathConstructor Fields[(0)],')'}}

    (Quotes around the parenthesis are optional but make it more readable i think)
