Validate Nested RadioButtonList

[WB]

Hi,

I have the following nested RadioButtonList in my web page that displays a
list of cities (categorized in states) for the user to select. There's a
RequiredFieldVa lidator to ensure user has selected one state.

<asp:RequiredFi eldValidator ID="VrqCity" runat="server" CssClass="error "
ErrorMessage="P lease select a city" ControlToValida te="RblCities" /><br />

<asp:Repeater ID="RptStates" runat="server"
OnItemDataBound ="GetBackPageTe mplates">
<ItemTemplate >

<strong><%# DataBinder.Eval (Container.Data Item,
"stateName").To String()%></strong>
<hr />

<asp:RadioButto nList ID="RblCities" runat="server"
RepeatDirection ="Horizontal " RepeatColumns=" 5" CssClass="text"
CellPadding="5" />

</ItemTemplate>
</asp:Repeater>

However, when the page is loaded, it shows the error:

Unable to find control id 'RblCities' referenced by the 'ControlToValid ate'
property of 'VrqCity'.

What's wrong?

HI,

In the code behind page check RadioButtonList is declared or not. Your code
should have

protected System.Web.UI.W ebControl.Radio ButtonList RblCities

The declaration is done by VS2005 in the partial class, and I can access
it's selectedValue etc in the code-behind.
