I am sure there are many ways to do this. I like Javascript:

    <script 
        language="javascript"
        function OnClientItemChecked(sender, eventArgs) { 
 
            __doPostBack('', ''); 
        } 
    </script> 
 
    <telerik:RadListBox 
        ID="RadListBox1" 
        runat="server" 
        CheckBoxes="true" 
        OnClientItemChecked="OnClientItemChecked"
        <Items> 
            <telerik:RadListBoxItem 
                runat="server" 
                Text="RadListBoxItem1" /> 
            <telerik:RadListBoxItem 
                runat="server" 
                Text="RadListBoxItem2" /> 
            <telerik:RadListBoxItem 
                runat="server" 
                Text="RadListBoxItem3" /> 
            <telerik:RadListBoxItem 
                runat="server" 
                Text="RadListBoxItem4" /> 
            <telerik:RadListBoxItem 
                runat="server" 
                Text="RadListBoxItem5" /> 
        </Items> 
    </telerik:RadListBox> 


Look for __doPostBack with javascript
This link is pretty useful as well
