I am trying to create a small form that will duplicate a users entry for them.On my form i have a text box and two CheckListBox controls and a button. The user should be able enter a value into the text box, and select multiple items from both CheckedListBoxes, when they click the submit button the details will be added to a DataGridView below.

This is an example,The user enters the value Audi A4 into the textbox.

The First Checked Lsit Box is called "Colour" and from the options the user checks 'Red' and 'Blue'.

The second Checked List Box is called "Number of Doors" and from the options the user checks '3' and '5'.

When the User clicks the submit button 4 rows will be added to the DataGridView with all the different combinations, as shown below:

Model Colour No# of Doors
Audi A4 Red 3
Audi A4 Red 5
Audi A4 Blue 3
Audi A4 Blue 5
