Unable to locate Grids or Windows

[phenry9999]

I am trying to test drive a WPF application. I have the WinAppDriver loading properly, and the Driver as well opening up my application. However, when I try to FindElement for a Window or a Grid, I get an error.
OpenQA.Selenium.WebDriverException: 'An element could not be located on the page using the given search parameters.'

My find is quite simple IMHO.
var mainWindow = Driver.FindElementByAccessibilityId("MainWindowGrid");

Likewise the xaml is simple.

<Grid.RowDefinitions>

.....

It seems like the only thing I can find is a Button. What am I doing wrong that I cannot locate anything useful? Please help. Thank you.

What is shown in inspect.exe?

I'm sorry, what is the inspect.exe tool? Do you mean after using the UIRecorder? I have both the automationid and a name in there but my Driver.FindBy methods give me errors.

I get the same error with the AutomationId

No the one that comes with windows SDK.

I found a copy of it. Trying it now. It shows the automation id I'm expecting when I hover over the menu option I want. What am I missing?

I think I found something. If I try to find the nested button, it won't find it....until I click the parent's File menu option. Is that required? Why can't it find the nested file menu exit button?
