What is the WPF XAML Data Binding equivalent of String.Format?

Question

Or, to be more clear, how can I format a block of text (in my case, to be included within a tooltip) such that some portions of the text come from bound values.

As far as I know, WPF doesn't do what you want. You do have a much more powerful (albeit more involved) solution.

Take a look at the IValueConverter interface.

EDIT

Based on aku's answer, and your assertion that you can't use 3.5 SP1, here's an alternative.

Take a look at Phil Haack's recent series of posts on string formatting:

• Fun With Named Formats, String Parsing, and Edge Cases
• Named Formats Redux

Create a ValueConverter as that takes the format as a property. You should then be able to bind your data object and have it format based on your defined format (using property name instead of position).
