@(Html.Telerik().Grid(Model)
.Name("Firms") 
.DataKeys(d => { d.Add(a => a.YourPrimaryKeyId).RouteKey("YourPrimaryKeyId");  })

For selection, you need a "identity key" or something like that (guid, string ..) to define an unique value of the row that is select.
 in your sample you didn't seem to have any Identity key, but you need to tell telerik grid one (why not 'telno' ?)
