.net - Binding to a property of an object through object[property] rather than object.property -

i've read through wpf data binding overview , feel should possible can't quite make mental leap here. know if set binding's path foo, , set source obj, binding @ obj.foo. in other words, obj.__getattr__() accessed.

all want make @ obj[foo] instead. i'm using ironpython , in case obj class has overridden __getitem__() calls member function , returns value, why need functionality.

here above example written programmatically. displays foo property of obj in checkbox:

mybinding = binding("foo") mybinding.source = obj           acheckbox.setbinding(checkbox.ischeckedproperty, mybinding) 

---

solution

it's simple this, apparently!

mybinding = binding("[foo]") mybinding.source = obj           acheckbox.setbinding(checkbox.ischeckedproperty, mybinding) 

you can use in binding, e.g. if datacontext/source has property

public string this[int i] {     get{...}     set{...} } 

you can create binding this:

<textblock text="{binding [0]}"/> 

edit: feel might have misunderstood question, if please tell me.
