When i define the client handler for calendar OnDateSelected event  i get strange action
as when i select date some dates after being set get change automatically to another date one or 2 days after the date i set

the code is as blow:
<telerik:RadDatePicker ID="calDOB" runat="server" Culture="en" MinDate="1900-01-01"
                Width="100%" TabIndex="5">
                <Calendar runat="server" UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x">
                </Calendar>
                <DateInput runat="server" DisplayDateFormat="d/M/yyyy" DateFormat="d/M/yyyy" TabIndex="5">
                </DateInput>
                <DatePopupButton ImageUrl="" HoverImageUrl="" TabIndex="5"></DatePopupButton>
                <ClientEvents OnDateSelected="SelectedDateChanged" />
            </telerik:RadDatePicker>

function SelectedDateChanged(sender,args) {
 
          var PckrBirthDate = $find('<%=calDOB.ClientID %>');
          var LblYears = $find('<%= TxtYears.ClientID %>');
          var LblMonths = $find('<%= TxtMonths.ClientID %>');
          var LblDays = $find('<%= TxtDays.ClientID %>');
 
           
 
          var birthDate = PckrBirthDate.get_selectedDate();
 
          if (birthDate != null) {
              var calday = birthDate.getDate();            
              var calmon = birthDate.getMonth();
              var calyear = birthDate.getFullYear();
              getAge(calday, calmon, calyear, LblYears, LblMonths, LblDays); 
          }
          else {
              LblYears.set_value("");
              LblMonths.set_value("");
              LblDays.set_value("");
          }           
      }
function getAge(date, month, year, yearControl, monthControl, dayControl) {
 
    today = new Date();
    dateStr = today.getDate();
    monthStr = today.getMonth();
    yearStr = today.getFullYear();
 
    theYear = yearStr - year;
    theMonth = monthStr - month;
    theDate = dateStr - date;
 
    var days = "";
    if (monthStr == 0 || monthStr == 2 || monthStr == 4 || monthStr == 6 || monthStr == 7 || monthStr == 9 || monthStr == 11) days = 31;
    if (monthStr == 3 || monthStr == 5 || monthStr == 8 || monthStr == 10) days = 30;
    if (monthStr == 1) days = 28;
 
    yearControl.set_value(theYear);
 
    if (month < monthStr && date > dateStr) {
        yearControl.set_value(parseInt(yearControl.get_value()) + 1);
        monthControl.set_value(theMonth - 1);
    }
    if (month < monthStr && date <= dateStr) { monthControl.set_value(theMonth); }
    else if (month == monthStr && (date < dateStr || date == dateStr)) { monthControl.set_value(0); }
    else if (month == monthStr && date > dateStr) { monthControl.set_value(11); }
    else if (month > monthStr && date <= dateStr) {
        yearControl.set_value(yearControl.get_value()- 1);
        monthControl.set_value(((12 - -(theMonth))));
    }
    else if (month > monthStr && date > dateStr) { monthControl.set_value(((12 - -(theMonth)))); }
 
    if (date < dateStr) { dayControl.set_value(theDate); }
    else if (date == dateStr) { dayControl.set_value(0); }
    else { yearControl.set_value(yearControl.get_value() - 1); dayControl.set_value(days - (-(theDate))); }
}

Hello Mohamed,

I tried to replicate the issue which you described, but to no avail.
Attached to this post, you will find the code which I used for testing.

Please, take a look at it and let me know if there are any differences at your end, which I may be leaving out.

All the best,
