Assigning radiobuttons
How do I assign radiobuttons to groups. Like radiobuttons 1-4 are in one group and you can select only one of the for the answer, and then 5-8 are in another group.

Try using the name attribute; i.e. same name for all radio buttons in the same group.

Hope it helps

Each ID must be unique for the Radio button. However, there is a GroupName property that groups them together. You can also use a radio button list control, which automatically groups the radio buttons together.

What is the radio button list control and how do I use it?

Is it a Web App?!
if so just set GroupName for ur RadioButtonObj.
or if its a HTML tag just set same name for each group!
Why do u make it so difficult?!

This isn't a web app. This is just a c# Windows Form.

Are you using Visual Studio .NET? Then try this:

1. Drop a Radiobutton control on your form.
2. Make sure it's selected and then press F1.
3. You'll get a list will all members of the RadioButton class.
4. At the top of the page, follow the RadioButton overview link and you'll see this:

quote:When the user selects one radio button within a group, the others clear automatically. All RadioButton controls in a given container, such as a Form, constitute a group. To create multiple groups on one form, place each group in its own container, such as a GroupBox or Panel control.
And there you have it. Just add some other containers like Panels on your form. Drag the Radiobuttons into the panel, so all Radiobuttons inside that panel will act as one group. Multiple panels means multiple groups.

Everyone is unique, except for me.
