Getting problem to get Rows from datagridview object in UI

description

I am testing UI test using nunit. But it fails when it tries to get rows count in grid. It is getting zero rows and table header as null. How Can I test datagridview ? I am using dot net framework 2.0.
 
For Reference below is error I am getting:

Please report the issue on GitHub (https://github.com/TestStack/White) if it is still an issue. Issues raised on CodePlex will not be fixed.
Also include the version of TestStack.White you are using.

Thanks!

I got resolution of above problem. If we make unit test project to test ui and run nunit gui to run unit test, it fails for getting rows of datagrid. But if we run unit tests using nunit-console with /nothread args then it works fine.

Thanks for the tip, this worked for me. From the brief test that I made, this also allowed me to find children of my menubar, which I was previously unable to do.

This is excellent if the /nothread option did the trick for you. This is new for me. I would add this to FAQ list.

I'm confused. This work item is supposed to be about the /nothread option and the comments are about that but the work item itself doesn't seem to cover that topic?

Nvm, it was a lack-of-coffee issue. /embarassed.
