I have data in a table like this.

-------------------------------------
|AC_NO   |   AC_TITLE      |AC_LEVEL|
-------------------------------------
|1       |ASSET            | 1      |
|1-01    |CURRENT ASSET    | 2      |
|1-01-001|SOME OHTER A/C   | 3      |
|1-02    |NON-CURRENT ASSET| 2      |
|1-02-001|SOME OHTER A/C   | 3      |

I have this data in a Grid.
Here i want the only AC_LEVEL = 3 be selected by mouse of by keyboard.
If I select AC_LEVEL = 1 or 2, the cursor should automatically move to next or previous available record (which is AC_LEVEL = 3).

Please help me on this.
