Hi Curt,
I've added my minimalized version below.
I experimented a bit more and can now substantiate the error (when it occurs
and how to reproduce).
If I use the attached code as it is (the line "single_radiobu tton.GroupName
= rbl.ID;" in the ascx-file "inputRadiobutt onlist.ascx" is not commented out)
and I take the following steps:
1) choose none of the radios
2) hit "submit"
--> button-method "Button1_Cl ick" (from "default.as px") is called correctly
(displays <DateTime.Now >)
3) choose one of the radios (only one possible)
4) hit "submit"
--> button-method "Button1_Cl ick" (from "default.as px") is NOT called
The same happens if close the site and reopen it and then choose at the
first step one radio (button-method won't be called).
If I comment only the line "single_radiobu tton.GroupName = rbl.ID;" out
everything works fine (except that I can choose both radiobuttons) but the
button-method will be called everytime when hitting "submit".
File "Default.as px" contains the following placeholder and button:
<form id="form1" runat="server">
<asp:PlaceHolde r ID="ph" runat="server"> </asp:PlaceHolder >
<asp:Button ID="Button1" runat="server" OnClick="Button 1_Click"
Text="submit" />
</form>

Where is your call to build the button list?
Is this being triggered from the Page_Load? If so, did you do the IsPostBack
check?

I have the following problem (especially with the groupname-attribut of the
RadioButton-Control) when developing in Visual Studio 2005 Beta.
I load an ascx-control in an aspx-page. This ascx-control itself creates
dynamically many radiobuttons in this way:
foreach (DataRow radiobutton_ite m in rbl_values.Rows )
{
RadioButton single_radiobut ton = new RadioButton();
single_radiobut ton.ID = "idname";
single_radiobut ton.GroupName = "groupname" ;
this.Page.Contr ols.Add(single_ radiobutton);
}
When loading the aspx-Page (and its controls) everything is fine and
groupname works as it should (I could only select one of the group). But when
a postback to this site occurs it seems that the listener of the
submit_button (placed on the aspx-Page) is killed. When I do not define the
Groupname of the RadioButton the submit_button works as it should (listeners
are not killed?!) but I can select more than only one radiobutton as I don't
have a group which they belong to.
I tried it already with an alternative:
single_radiobut ton.Attributes. Add("name", mygroupname) instead of
single_radiobut ton.GroupName = "groupname" ; (seen in
http://msdn.microsoft.com/newsgroups...7ec&sloc=en-us)
but this didn't help.
Do you knwo this issue?
