I can also verify that the same problem exists on OnRecordDoubleClick Event and OnToolbarClick evnt.
I think this problem is in every event called by the grid.

Greeting from Syncfusion support.
Query: “On the RowSelected event from grid i want to change the text variable and call StateHasChanged(); Also if i only call StateHasChanged in that event, the grid is not useable any more.”
As per your suggestion we have prepared a sample in our latest Nuget version (184.108.40.206) and we are not able to reproduce the reported issue at our end. We are able to modify the text using OnToolbarClick, RowSelected and OnRecordDoubleClick events.
For your convenience we have prepared a sample which can be downloaded from below link
