Control type depends on data type or property?

Tall Bill Clark asked:

Quick question:
Is is short work using XAML to have the types of controls configured/controlled by the underlying data. I see plenty of examples of configuration of a control's look/feel based on data content; I am looking to base the control type on the associated data/properties.

Examples include:
. Value returns Bool object, the control should be a button
. Value returns Int32 object, the control should be a textbox
or
. The data could expose a property, Widget, that would specify button, textbox, etc

I suppose one could write this in C# pretty readily or cobble together a ContentControl that contains all possible button, textbox, etc combination and the data could control which are visible but these seem such hacks. I thought I would ask the experts if a more natural xaml solution exists.

When answering a question please:
  1. Read the question carefully.
  2. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
  3. If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
  4. Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.
