I allow the user to add new ComboBoxes everytime they click add item. Now if there are two comboBoxes, when they select an item from the second one, it changes the first one as well. How do I stop that from happening, so each comboBox has there respective selections.

I think that is happening because you are using the same datasource for all the combo boxes. As a quick fix try cloning the 'storeNameArray' when you assign it to the data source of the combo box. Alternatively create a new array each time and you the Array.CopyTo() method to populate the new array from the 'storeNameArray'. If you study the data-binding options you might find a better solution. I'm mainly doing ASP.NET so I'm a bit rusty on data-binding in Windows forms.
