Hides the active editor and posts all the changes made within the focused row to a data source if the row values are valid.
true, if the values within the focused row's cells are valid; otherwise, false.
By default, the grid automatically validates the changes made within the focused row when the row focus is about to be moved to another row. If all the new values are valid, they are posted to the grid's data source. Otherwise, the row remains focused until an end-user corrects invalid values. To manually force row validation, use the CommitEditing method. If the validation fails, new values are not posted to a data source, and the CommitEditing method returns false. Otherwise, new values are saved and the CommitEditing method returns true.
