Hi,

I suppose you want to hide the invalid icon. Here is the sample code.
JS:

var pkr = $find("<%= RadDatePicker1.ClientID %>");
pkr.get_dateInput()._invalid = false;

Thanks,

solved here is the code 

    var rdpEventStartDate = $find("<%= RadDatePicker1.ClientID %>");

    var rdpEventEndDate = $find("<%= RadDatePicker2.ClientID %>");

 

    rdpEventStartDate.get_dateInput()._holdsValidValue = true;

    rdpEventStartDate.clear();

 

    rdpEventEndDate.get_dateInput()._holdsValidValue = true;

    rdpEventEndDate.clear();
