I am using RadWizard steps to make a survey. One step in the Radwizard is to select at least one service they use out of the list of options. When next button is hit, I need to validate that at least one item was checked. If I click next without checking anything, it just goes right to the next step. If I check then uncheck a box, only then does my "Please choose at least one of the options displayed" show up, and it still lets me hit next. What am I doing wrong? I also tried adding the auto postback =false to the Radwizard step, and the Radcheckboxlist itself, and neither helps. Not sure what I am doing wrong. My code looks like this:
<telerik:RadWizardStep ID="RadWizardStep2" runat="server" Title="Services">
<div>
<h3>Please mark all that apply:</h3>
<br />
<br />
<telerik:RadCheckBoxList ID="RadCheckBoxList1" runat="server">
<Items>
<telerik:ButtonListItem Text="Residential Services" Value="2" />
<telerik:ButtonListItem Text="Vocational Services" Value="3" />
<telerik:ButtonListItem Text="Transportation/NMT Services" Value="4" />
<telerik:ButtonListItem Text="Recreational Services" Value="5" />
<telerik:ButtonListItem Text="Supportive living services" Value="6" />
<telerik:ButtonListItem Text="Supported employment services" Value="7" />
<telerik:ButtonListItem Text="Other" Value="1" />
</Items>
</telerik:RadCheckBoxList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="RadCheckBoxList1"
ErrorMessage="Please choose at least one of the options displayed" />
</div>
<div>
<telerik:RadTextBox ID="OtherTextBox" runat="server" Visible="false"></telerik:RadTextBox>
</div>
</telerik:RadWizardStep>
