Simple Radio button problem

[lesliedomjones]

hello all,
I have two webforms radio buttons in a same group. Through Code I am setting second radio button as checked by default. ie, In ASPX page it looks like as shown below..

<asp:RadioButton id=&quot;rdoSOne&quot; runat=&quot;server&quot; Text=&quot;ServerOne&quot; GroupName=&quot;groupname&quot;></asp:RadioButton>

<asp:RadioButton id=&quot;rdoSTwo&quot; runat=&quot;server&quot; Text=&quot;ServerOne&quot; Checked=&quot;True&quot; GroupName=&quot;groupname&quot;></asp:RadioButton>

now through code (ie, in CS file) I am trying to change the status of the radio button by giving the code as shown below.

rdoSOne.Checked = true;

But it is not working.. But if I explicity give

rdoSOne.Checked = true;
rdoSTwo.Checked = false;

It is working fine.. I know the problem. But I dont know is there any other way by which this problem can be overcome? Or is it a dotnet bug? Experts please help me...

Thanks in advance...

Regards,
