Add dynamic row in data grid with drop-down.

Hi Guys,

I am trying to add a row dynamically to datagrid, the last two columns are drop down, I am using below statement but the drop down is not getting populated.

dg.Rows.Add(new object[] {name,address,phone, office, item, price, "",dc,"","","","","","","","TBD","No"});

The last two items,

"TBD" and "No"  are suppose to be drop down in datagrid, but the dropdown is not getting populated.

Any help would be appreciated.
