Remarks
Setting the KeepFocusedRowOnUpdate property to false is in effect when the data source is not managed by the CurrencyManager (see ColumnView.DisableCurrencyManager).
If the KeepFocusedRowOnUpdate property is set to false the value of the ColumnView.FocusedRowHandle property is not changed when the data source is modified or when data is sorted, grouped or filtered using the Grid Control UI. Therefore, focus may move to another row when any of these actions is performed.
In the following example, a sample Grid Control displays three records sorted by the ‘Order ID’ column in descending order. The second record (OrderID=10249) is focused.
Assume that a new row (OrderID=12001) is added to the data source. According to the current sort settings, this row will be positioned above all existing rows, and the currently focused row (OrderID=10249) will be moved down.
If the KeepFocusedRowOnUpdate property is set to true, the currently focused row (OrderID=10249) will remain focused after the new row is inserted:
If the KeepFocusedRowOnUpdate property is set to false the value of the ColumnView.FocusedRowHandle property is not changed after the new row is added. Therefore, the row with OrderID=10250 will be focused.
