Accessing dynamic radio buttons

I have a placeholder where I dynamically add radio buttons based on values
from a DB. It's all one group. How can I access them so that I know which
one is selected?

I've tried both input type="radio" and asp:radiobutton

I can't seem to add a checked.changed event to the radiobutton and when I
search through the assorted controls on the page, I can't find the control
anywhere (through code.)

TIA - Jeffrey.

This is all possible. When there is a postback you need to recreate the same
controls that you had previouly dynamically created. Here's a sample that
shuld get you started:

Brock,
Thanks I think. But that doesn't really answer my question. I have the
creation of the radiobuttons working fine. The problem is - I need to know
which radio button is selected.

Any suggestions?

TIA.

When you dynamically create them handle the SelectedindexChanged event. The
first paramater is the sender of the event, which will be your RadioButtonList.
Or am I still missing what you're trying to do?

I'm not using a radiobuttonlist - I have a series of radio buttons. The
reason for the individual radio buttons is that I need more layout control
than what a radiobuttonlist will give me.

So you can handle the OnCheckChanged event for the RadioButton, and in the
event handler the first parameter is the sender which is the RadioButton
that was checked. I hope this helps?
