c# - How can I tell if an element matches a PropertyCondition in Microsoft UI Automation? -

i'm trying find automationelement in particular row of gridview (so there many identical elements). i'm iterating on elements in row, , i'd use matcher see if particular element matches condition i'm passing it. i'm starting simple propertyconditions.

here's test:

[testfixture] public class conditionmatcherbehaviour {     [test]     public void shouldmatchapropertyconditionbyitsvalue()     {         var conditionmatcher = new conditionmatcher();         var condition = new propertycondition(automationelement.controltypeproperty, controltype.pane);         assert.true(conditionmatcher.matches(automationelement.rootelement, condition));     } } 

and here's code:

public class conditionmatcher : imatchconditions {     public bool matches(automationelement element, condition condition)     {         var propertycondition = (propertycondition) condition;         return propertycondition.value.equals(element.getcurrentpropertyvalue(propertycondition.property));     } } 

unfortunately test fails. controltype of root element (the desktop) indeed controltype.pane, bizarrely propertycondition.value "50033".

any ideas how can test propertycondition outside of findfirst / findall?

(my workaround create own condition type , test instead, i'd check i'm not misunderstanding / doing stupid.)

found it.

public class conditionmatcher : imatchconditions {     public bool matches(automationelement element, condition condition)     {         return new treewalker(condition).normalize(element) != null;     } } 

not obvious, works both matching , non-matching conditions. looked , thought bit. else!
