  Hi,
  
  I am using rad datepicker and i am clearing it if today or future date is selected and i am using it as below
  Note: IT IS USED IN GRID'S EDIT FORM SETTING.
  
   function OnToDateSelected() {
                  var HidCurrentDate = document.getElementById("ctl00_MainContent_hidCurrentDate");
                  var CurrentDate = DateConversionForHidden(HidCurrentDate.value);
  
                  var ServerIdRadioBtnlst = "rblOwnerTypeC";
                  var tagNameRblbtnList = "input";
                  var rblListC = GetGridServerElement(ServerIdRadioBtnlst, tagNameRblbtnList);//this will find the id of control used in grid in js
  
                  var ServerIdRadioBtnlst = "rblOwnerTypeP";
                  var tagNameRblbtnList = "input";
                  var rblListP = GetGridServerElement(ServerIdRadioBtnlst, tagNameRblbtnList);
                  if (rblListP.checked == true) {
  
                      var serverIDTo = "rdpPeriodTo";
                      var tagNameTo = "input";
                      var rdpPeriodTo = GetGridServerElement(serverIDTo, tagNameTo);
                      var ToDate = DateConversion(rdpPeriodTo.value);
  
                      if (ToDate >= CurrentDate) {
                          alert("you can't use current or future date in previous Owner");
                          rdpPeriodTo.clear();
                          return false;
                      }
  
                  }
               
              }
  
  <telerik:RadDatePicker ID="rdpPeriodTo" runat="server" Width="105px" Style="float: left;
                                              margin: 10px 0px 0px 0px;" ClientEvents-OnDateSelected="OnToDateSelected">
                                              <DateInput ID="DateInput2" runat="server" Font-Names="Georgia" >
                                              </DateInput>
                                              <Calendar ID="Calendar2" runat="server" ShowRowHeaders="false">
                                                  <SpecialDays>
                                                      <telerik:RadCalendarDay Repeatable="Today" Date="">
                                                          <ItemStyle CssClass="rcToday" />
                                                      </telerik:RadCalendarDay>
                                                  </SpecialDays>
                                              </Calendar>
                                          </telerik:RadDatePicker>
  
  above functionality is showing javascirpt error "Error: rdpPeriodTo.clear is not a function". I think it is not working due to rad date picker used in Grid .... but i am getting the id of that rad date picker by using GetGridServerElement() method (provide by telerik). Please help me it is urgent.

  Hello Manish,
  
  You need to modify the signature of your client-side OnToDateSelected method. It needs to be:
  

  function OnDateSelected(sender, args)

  {

  ...

  }

  
  Now, sender will hold a reference to your RadDatePicker and you can just call its clear() method: sender.clear().
  
  Hope it helps.
