C# - Custom DataSet within the form

Question

Hi,

A newbie needs some help. I have a custom SQL connection and what I wanna do is, I wanna create a DataSet using this SQL connection. And I wanna be able to call this dataset from any method within the form. Just to be clear let's say :

I have gridcontrol named gridcontrol1, a button called button1. When I click to the button it should bind that dataset to the gridcontrol.

So I want to be able to call this dataset with different events.

I don't know how to make that dataset be able to called from anywhere in the form. Where should I put my codes for my dataset and in what (in a method, a new class or somewhere else?)

Thanks in advance.

EDIT :

I knew it. It's so easy. But as I said I'm a newbie. So here is my solution :

I defined my connection, dataset etc. like :

public static SqlConnection conn;

public static DataSet ds;

....

So I solved my problem...
