This example describes how to conditinally disable row selection and selection checkboxes.
We recommend handling the selectionChanged event to prevent selecting disabled checkboxes. However, the Select All checkbox will work incorrectly after that. The cause of that issue is that dxDataGrid doesn't support this scenario out-of-the-box. A workaround for this scenario is shown in this GitHub repository. In this example, a row is disabled if its Approved value is false. The limitation of this workaround is that the remoteOperations option should be false.
