DataGrid ComboBox Cell in Pocket PC applications

Hi all,
i need to use Datagrid combobox cell in Pocket PC. I know that it is possible to use DataGridViewComboBoxCell in DataGridView, but compact framework only includes datagrid and that's why i can't use DataGridViewComboBoxCell. I tried to use DataGridCustomComboBoxColumn to solve that. It is working if i have fixed values for all rows but i need to change the values of comboboxes in each row. (I tried a few alternatives to solve that but it didn't work because i can't use the column as cell so can't change the values of the comboboxes in each row) Can you recommend me a solution to manage that?
Thanks...
