I also have populated GridDropDownColumn if it is in editable state with a hashtable in ItemDataBound event  of RadGrid.Means it will only be populated with hashtable in edit mode or add mode.

How ever when i add a new record in the grid and press ok...it shows me all the data values in this GridDropDownColumn field.

Please tell me the solution of this problem

Secondly tell me the way how can i store some values in this GridDropDownColumn  in ItemCommand event when in edit mode.

Reply me ASAP.
