Can not find the control, which is a dynamic table...

Hi I am dynamically generating a html table 'DBTable' and populating the data.
Later I can not find this table and used these methods...

FindControlRecursively("DBTable", Page)
FindControlRecursively("DBTable", form1)
Pls check my code and let me know how to fix this....Thanks
