Question

I’m using a standard form rather than an ASP.Net form and posting it so my controls are not server controls.

I have a group of 3 radio buttons all with the same name (so that they group together). But when I use

Request.Form["input_radiogroup"]

I just get the value “on”. How can I find out which radio button was on if they all have the same name?

Answer 1

The value returned from Request.Form["input_radiogroup"] will be the value of the selected radio input form element.

For example:

<input type="radio" name="input_radiogroup" value="0" />
<input type="radio" name="input_radiogroup" value="1" />

The possible values will be either 0, 1 or null (if none are selected).
