I tried to implement an onchange event for RadDatePicker but received the error:
Error: Object doesn't support property or method 'addEventListener'
when I used this javascript:
function startDateChanged() {
alert('date changed');
}
pageLoad(){
var sDate = $find("<%=SDate.ClientID %>");
sDate.onchange = startDateChanged;
sDate.addEventListener("change", startDateChanged, true);
}
