Title: property binding and read only properties
Post by: beermoney on May 22, 2014, 10:06:37 AM

Hi,

I am finding that I can't set a read only property as the source of a property binding.

ie. if the component I try use as a source has the following read only property:
   

1. public string LevelDescription {
2.                 get {
3.                                 return "Lv." + _Level;
4.                 }
5.         }

LevelDescription wont appear in the dropdown in the source property binding component in the editor.

if I change it to:
       

1. public string LevelDescription {
2.                 get {
3.                                 return "Lv." + _Level;
4.                 }
5.                 set {}
6.         }

then that property is now available in the dropdown of available properties and fields.

Bug or as per design?  (I can imagine that it might be a requirement for bi-directional data binding but that's something I may not be using)

thanks

It's by design.

ok

may I ask why is that is by design?

Because I want the flow of data to be bi-directional. It just simplifies things.

just so you know it means it's extra code for everyone who doesn't need the bidirectional functionality...
(and writing set{} in properties just looks messy)

also I didn't think it actually supported properties until I looked under the hood
