saving C# windows form checkbox value of 1 or zero into a sql server or oracle table

I have a basic checkbox in a C# windows form. Lets say the form is called   Form1.cs

In my form I brought in the checkbox controls for 3 checkboxes.

I have created a column in my database table for each check box value.

So if the check box is checked the value that will go in the column will be 1
if the value in the checkbox is not checked the value in the column for that checkbox remains 0.

Whats the easiest cleanest way to set up this form?

say i have 3 checkboxes that are called the following

checkbox1
checkbox2
checkbox3

My database is a SQL server database.

The table is called CheckboxDB
The columns in this db are:

checkbox1value
checkbox2value
checkbox2value
