Get the selected input type radio button ASP.NET

Question

I have two radio buttons:

<input type="radio" name="group1" />1
<input type="radio" name="group1" />2

How do I know which one is selected when the form is posted?

Answer 1

The inputs should have values:

<input type="radio" name="group1" value="1" />1
<input type="radio" name="group1" value="2" />2

Then, the value will be posted on the name group1. On Asp.net you can get it using:

Request.Form["group1"]
