Problem with combo boxes using Visual C# with .NET

I'm just starting using Visual C# with .NET to try to write a front-end for an Access DB. I have three combo boxes

which should be 'Yes/No'. Problem is that if I change value in one, they all change! Any ideas? I am a bit confused here. Do you mean combo box, check box or radio button? Typically for yes/no answers, one would use a checkbox. Radio buttons work in groups. If you place several radio buttons on a form, they are part of a group based on the form. Only one will be selectable at a time. Use a GroupBox to organize radio buttons into groups.

Checkboxes are usually used to provide a Yes/No response. They tend to be easier to use and understand than having a series of drop-down combo boxes.

As to your specific question, without the code for the form I can't tell you why that behavior may be occurring.
