Problem in using SearchCriteria.ByAutomationId(id)

Oct 19, 2010 at 9:13 AM

Hi all,

  I am trying to recognize a window with the following line of code,


Window win = App.Get<Window>(SearchCriteria.ByAutomationId("id"));

but it's throwing an error as "White.Core.Application" does not contain a definition for 'Get' and no extension method 'Get' accepting a first arguement White.Core.Application could not be found. Could any one please tell me if i'm missing any reference to any dll files ? I'm confused about which i'm missing.


Thanks in Advance.

Window window = App.GetWindows().Where(p=>p.AutomationElement.Current.AutomationID =="id").First();

Thank you Throndorin,


  But the same error for "Current" in the line you have provided.

Window window = App.GetWindows().Where(p=>p.AutomationElement.Current.AutomationID =="id").First();

Not able to find System.Windows.Automation.AutomationElement

I'm looking for that dll in my machine but no success.

Thanks in advance.

in Visual Studio look for UIAutomationClient, UIAutomationClientsideProviders, UIAutomationProvider and UIAutomationTypes as References

Ok I ma

de reference to all dll's mentioned but It still has some problems. I'm not able to understand what the P is in your code ? It says p is does not exist in this context.


Thanks in advance

this is a Linq expression (using System.Linq;)

is the same as I write:



foreach(Window window in windows)
  if(window.AutomationElement.Current.AutomationID == id)
    return window;
