Based on the attached screenshot (Webgrid has checkbox column.PNG) in your initial post, I created a simple page of WebGrid with following detail:

• The grid has a checkbox column.
• AllowFilter is enabled.
• AllowAddNew and AllowBatchUpdate also enabled.

Per my test, copy and paste row from context menu works as expected. For your reference, I enclosed my sample file and a video that shows how the test was performed in my local end.

I'm using WebUI.NET Framework 3.0 (3.0.5000.975); WebGrid 10 (10.0.7200.24); and WebDesktop 5 (5.0.7200.49).

We found that checkbox column was not bool type and handled another way. After changing column type as bool. It started working as expected.

Glad to hear the good news.
