Seach button with textbox (C# and Oracle database)

Question

Hi people i need help for codding a search button with textbox that searches anything in my oracle database using c# from my windows form,
iam sorry if iam not very clear because my english is not very good and iam pretty new to visual studio 2010 ultimate

eg: lets say i have this:



what i want is, when i press search, it searches the database or tables involved and returns me a datagrid with all records that contain Raul in it.
Iam using c# and the database is Oracle 11g.

Thank you very much.
