Hi Michael,
You can track the row context menu of the grid in this page: https://feedback.telerik.com/blazor/1444877-contextual-menu-for-the-grid-rows

Until Telerik is providing a contextmenu blazor component you might want to use this:

I expect that the suite will have a context menu at some point in the future. At this moment we are working on a "regular" menu and a treeview for the upcoming releases, but we will keep an eye on this request and its popularity, and we will bump a context menu higher if this gets upvoted.
