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>

No answers yet. Maybe you can help?
