Did I miss installing something.
Used the installer telerik.ui.for.blazor.2.1.0.commercial.msi
Would be nice to have a MapView for Blazor. Is this in the works?

ADMIN EDIT
In the meantime, you can use the Kendo Map widget in a fashion similar to this project.

Using the new Grid grouping feature in 1.6, the Grouping button and the group header row both use the field name of the group column, rather than the title. This is visible in the animated demo, where a column titled "On Vacation" becomes "IsOnLeave" once it is used as a group name.
I expect this is already known and slated to be fixed, but there aren't any grouping issues at all in the public tracker, so just in case...
For the Grid, is is possible to have a a SortField along with Field (that displays the data) in columns.
The SortField will be used instead of Field when sorting (if Grid is Sortable), like in WebForms: https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.webcontrols.gridview.sortexpression?view=netframework-4.8.
Maybe you want to sort data based on other values instead of what is displayed.
This could be especially useful for dates that have been formatted for display in Field
but you don't want to use for sorting because date and string sorting is not the same.
The CSS classes used by Blazor UI are not documented. (I haven't looked outside the Blazor area, so maybe it's somewhere else in the docs? My team has no need for other Telerik products.) On a similar note, the Themes page in the documentation explains how to reference alternate themes like Bootstrap, but it doesn't explain how to actually use the classes, or how it integrates with the real Bootstrap CSS, which have many various useful, well-known utilities like margin and padding settings, which don't seem to be part of the Telerik theme support. (I'm an architect at a very large corporation, we do have one of those includes-everything DevCraft licenses, I just can't log in with that account.)
If filtering is enabled, the error may prevent the view from rendering similar to NotImplementedException: Unexpected frame type during RemoveOldFrame: None.
Without filtering, an exception is thrown when you attempt to edit a field, similar to Error: System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Nullable`1[System.Int64]'.
You may get an exception like
InvalidOperationException: The current thread is not associated with the Dispatcher. Use Invoke() or InvokeAsync() to switch execution to the Dispatcher when triggering rendering or modifying any state accessed during rendering.
or you may get components that simply don't work (for example, a Window does not show, a treeview does not expand).
The solution is to revert to the RenderComponentAsync method in your _Hosts.cshtml file.
What about supporting INotifyCollectionChanged data source for the Grid?
When trying to create a treeview inside of another treeview template I get the following error
[2019-07-19T00:58:28.003Z] Error: System.InvalidOperationException: Object of type 'Telerik.Blazor.Components.TreeView.TelerikTreeView' does not have a property matching the name 'ChildContent'.
