    I have a Combobox with values as below and I need to be able to disable (grey them out) the Active and Blocked values as soon as the user selects ALL. If one of the non-ALL values is selected and then ALL is selected, ALL must remain the only selected value and the rest auto-unchecked.

    The challenge is that this must be performed clientside without postback.

    Is it possible?

    <telerik:RadComboBox runat="server" ID="rcbStatus" Width="250px" CheckBoxes="True">
         <Items>
             <telerik:RadComboBoxItem Text="ALL"/>
             <telerik:RadComboBoxItem Text="Active" />
             <telerik:RadComboBoxItem Text="Blocked">                                               
         </Items>
     </telerik:RadComboBox>
