WPFCustomControls::Converters::MultiBooleanToVisibilityConverter Class Reference

---

Detailed Description

Converts a sequence of booleans and returns Visible or Collapsed according to the logical result.

You can make this and AND gate, or an OR gate, by setting the LogicalAnd boolean property. If you make it an AND gate, then we respect parameter ordering so that an effective null check can be introduced earlier that will result in a later, possibly invalid argument being skipped. This is similar to:

if(null != ref AND ref.SomeProperty) {

Similarly, a true result on an OR will always result in an early exit.
