        i have one combox and some checkbox

    <telerik:RadComboBox ID="ddlAction" Width="120px" EnableEmbeddedSkins="false"
                                                                Skin="IELSkin" Height="55px" runat="server" OnClientSelectedIndexChanged="fnSetAction">
                                                                    <telerik:RadComboBoxItem Text="--Select Action--" Selected="true" Value="0" />
                                                                    <telerik:RadComboBoxItem Text="Copy" Value="2" />
                                                                    <telerik:RadComboBoxItem Text="Delete" Value="1" />

    <asp:CheckBox ID="chk1" runat="server" />
    <asp:CheckBox ID="chk2" runat="server" />
    <asp:CheckBox ID="chk3" runat="server" />
    <asp:CheckBox ID="chk4" runat="server" />

    if i select any of these copy or delete form combox i have to check wheather is there any checkbox check.
    if not i have to raise the alert and make the combox selection to the "--Select Action--"..

    i am using  select() method
    but if i use this method it again fires the OnClientSelectedIndexChanged starts looping
    somehow i have to stop this firing event
    i tried get_selected()  method but it doesn't work.

    function fnSetAction(sender,args)
         //Check if any check box is checked
    var ddlAction11 = sender

    please suggest me some solution as soon as possible.
    Waiting for your fruitfull reply

    Hi Shrirang Dhere,

    You could attach 'OnClientSelectedIndexChanging' to RadComboBox, so that you can cancel the selectionchange event if any of the checkboxes are not checked.


        function OnClientSelectedIndexChanging(sender, args) {  
            // Check if any checkbox is checked  
            args.set_cancel(true);  // Cancel the event if any of cehckboxes not checked
