    Hi,

    I am new to telerik controls and I have inherited a website that heavily relies on Telerik controls.

    I have created 2 raddatepickers. One of them has a client event OnDateSelected that updates the 2nd datepicker with a calculated date based on the first one. This works fine until another control on the same page/panel causes a partial postback (using the RadAjaxManager). After the partial postback my client event can no longer access the raddatepicker client object.

    I have set the client event to be reattached after the partial postback. I don't know if that is necessary. ( I assumed it was based on this page http://www.telerik.com/help/aspnet/toolbar/toolbar_clienteventsunattached.html). I know that the event is reattached b/c I have stepped into the code using Firebug. However, when the set_selectedDate function runs nothing happens to the 2nd datepicker.

    Here is the code that I used:

                  <telerik:RadDatePicker ID="dateTetanusReceived" runat="server">
               <ClientEvents OnDateSelected="TetanusDateSelected"></ClientEvents>
                </telerik:RadDatePicker>
                  <telerik:RadDatePicker ID="dateTetanus" runat="server">
                </telerik:RadDatePicker>
    var _TetanusExpiryPicker = $find("<%= dateTetanus.ClientID %>");
     var _TetanusPicker = $find("<%= dateTetanusReceived.ClientID %>");
     
    function TetanusDateSelected(sender, e) {
     
        SetSecondDatePicker(_TetanusExpiryPicker, 10, e);
    }
     
    function SetSecondDatePicker(datePicker, yearsToAdd, e) {
        var expiryDate = e.get_newDate();
        expiryDate.setFullYear(expiryDate.getFullYear() + yearsToAdd);
        datePicker.set_selectedDate(expiryDate);
    }
     
    //Event gets called after a partial postback ends
    function OnResponseEndHandler(sender, arguments) {
     
        _TetanusPicker.add_dateSelected(TetanusDateSelected);
    }

    Any help would be appreciated.

    Hello Oran,

    I tried to replicate the issue which you described, but to no avail.
    Attached to this message, 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.

    Additionally, I would like to mention that it is not necessary to reattach the event handlers after partial postback.

    All the best,
    Mira
