ok that seems to work.

just weird that the handled parameter is specifically mentioned in the api docs.

copied from https://www.htmlelements.com/blazor/blazor-ui/demos/blazor-grid?id=features right upper hand “Quick Actions” – “API docs”
<table class=”table”>
<tbody>
<tr>
<td>OnCommand</td>
<td>Action<object></td>
<td>N/A</td>
<td>Callback function, which is called when a command is executed. The name argument is the command’s name. The command argument is the command’s function. details are built in command arguments passed by the Grid. The handled parameter allows you to cancel built-in command, because when you set it to true the Grid will not execute the default command’s behavior.</td>
</tr>
</tbody>
</table>
 

I assume the documentation is not correct then?
