            <ClientEvents OnRequestStart="RequestStartedOfRadAjaxManager1" /> 
            <AjaxSettings> 
                <telerik:AjaxSetting AjaxControlID="RadComboBox1"
                    <UpdatedControls> 
                        <telerik:AjaxUpdatedControl ControlID=" RadComboBox1" /> 
                        <telerik:AjaxUpdatedControl ControlID="ChechBox1" /> 
                    </UpdatedControls> 
                </telerik:AjaxSetting>

Hi Majid,

Could you please elaborate a little bit more on your scenario? Does the application work correctly if the Ajax is disabled on the page? Also please try using regular asp Update Panel and verify if the same problem appears.

Hello Majid,

By default the CheckBox1_CheckedChanged event will fire when you directly click on the control. For the needs of your application you should set the alert on the RadComboBox1_SelectedIndexChanged event for the correspondence state of the CheckBox.
