Any error in catch block?

no error inside the catch block

ConnectDatabase() is working? ur pointing to correct DB? cpde looks good. should insert the record... check connections and and connection string.

command.Parameters.AddWithValue("@stock_code", CType(e.Item.FindControl("stockCode"), Label))

You try to insert a Label in to your database?
If not then change it to:
command.Parameters.AddWithValue("@stock_code", CType(e.Item.FindControl("stockCode"), Label).Text)

put all your code in try exception block and let us know what the error message is

(your code)
Catch ex As SystemException
Catch ex As SQLException
