I'm having trouble with a simple radio set of two radio buttons (I don't want to use a RadioButtonList [RBL] because RBL doesn't allow child controls, and in my
case, if you select one option, I want to enable a textbox next to the button; yes you could hack this with jQuery to move the textbox, but that's dirty!). I would check one, submit the form (either explicitly or through AutoPostBack), and the CheckedChanged event would never fire. When the page was reloaded, both buttons would be unchecked, regardless of their initial state on non-postback load or the state before form submission.
I took out the checkbox and stripped this down to the simplest example I could come up with. I tossed EnableViewState=true all over the place just in
case it was being disabled somewhere I couldn't find.
<form id="form1" runat="server" enableviewstate="true">
<div>
<asp:RadioButton ID="foo" Text="foo" runat="server" AutoPostBack="true" OnCheckedChanged="rbChanged" Checked="true" GroupName="foobar" EnableViewState="true" />
<asp:RadioButton ID="bar" Text="bar" runat="server" AutoPostBack="true" GroupName="foobar"
OnCheckedChanged="rbChanged" Checked="false" EnableViewState="true" />
<asp:Label runat="server" ID="resultLbl" />
</div>
</form>
protected void rbChanged(object sender, EventArgs e)
{
if (foo.Checked) resultLbl.Text = "foo is checked";
else if (bar.Checked) resultLbl.Text = "bar is checked";
else resultLbl.Text = "neither is checked";
}
