Hi All,
I have an app that I wish to have 2 radiobuttons (or a radiobuttonlist)
Currently I can't seem to get any c# code to do anything, even though I have my oncheckchanged command in the aspx in the appropriate tag. Is there anything else i'm missing?

Not entirely sure about you, but what we are missing is sample code of the problematic page.... ;-)
Post the relevant parts of the so we can take a look at it....

Haha fair do's!
My aspx
<asp:RadioButtonList ID="RadioButtonList1" runat="server" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
<asp:ListItem>Internal</asp:ListItem>
<asp:ListItem>Commercial/General/NHS</asp:ListItem>
</asp:RadioButtonList>
c#
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
MessageBox.Show("Radiobutton");
}
any thoughts?

Certainly. You are mixing Web Forms and Win Forms. Take a look at this:
MessageBox.Show("Radiobutton");
Where do you think this fires? At the client? Nope; this fires at the server and does NOT translate into something like an alert() call. In ASP.NET applications, you can't use MessageBox.Show. I think it's just swallowed by the framework.
Try writing to a Label instead. E.g. add a <label /> control to the page and then try:
Label1.Text = "Radiobutton";
Maybe you are new to ASP.NET? If so, you may want to check out my new book Beginning ASP.NET 3.5, located here: http://www.wrox.com/WileyCDA/WroxTitle/productCd-047018759X.html

Sorry, MessageBox is a c# method I have written that uses Javascript, so it can popup buttons on the clients. The radiobuttons reference si just to pop up a textbox saying radiobutton to see ti go into the event, but this isn't the case.

But did you try out the label I suggested? Maybe your MessageBox code isn't working?

Apologies, I must have been having a bad day. I have got it working now. I wasn't posting back the changes so couldn't see my changes...
