Hi,
I'm using the Prometheus version of your controls, particularly version 2007.3.1314.20, and for some reason the SelectedDateChanged event of the radDatePicker is firing twice.
This is my html code:
And this is the source code:
So I put in a break point for the SelectedDateChanged event and it's always firing off twice, and in the big project I'm working on that makes some things not work as expected. Do you guys know why this is happening?

| <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="TelerikCalendarTest._Default" %> |
| <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> |

| <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1"> |

| <telerik:RadDatePicker ID="test" runat="server" AutoPostBack="true"></telerik:RadDatePicker> |
| </div> |
| </form> |
| </body> |
| </html> |
And this is the source code:
| Imports Telerik.Web.UI |
| Imports System.Collections.Generic |
| Partial Public Class _Default |
| Inherits System.Web.UI.Page |
| Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load |
| End Sub |
| Private Sub test_SelectedDateChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs) Handles test.SelectedDateChanged |
| End Sub |
| End Class |
So I put in a break point for the SelectedDateChanged event and it's always firing off twice, and in the big project I'm working on that makes some things not work as expected. Do you guys know why this is happening?

Hi Chris,
The code seems to be correct and I'm afraid I don't remember such a problem reported/fixed so far. I tried that with the latest Q2 2008 Service Pack version labeled 2008.2.826, but could not reproduce the described issue as well.
Just a quick question though, do you run that AjaxSetting this way or do you have the DatePicker set as AJAX initiator as well? Can you try adding RadDatePicker -> RadDatePicker AJAX setting instead and see whether that causes different control behavior? The AJAX setting should look like this:
Additionally, is the event fired twice when you remove the RadAjaxManager or simply disable it temporary (set EnableAJAX false)?
Kind regards,

It fires twice with and without the Script Manager. I also tried setting up the AJAX settings like you described and still no luck. Could it have anything to do with me setting the autopostback property? I need to set that because the calendar interacts with another control.

Hello Chris,
You definitely need to turn on the AutoPostBack to be able to trigger an AJAX request. RadAjax controls simply converts all the regular postbacks into AJAX requests.
Please find my test page attached. If the events is fired twice with this page as well, it might be an issue with the old version of Telerik.Web.UI.dll.

Yeah, it's still firing twice. I'll have to wait to use the control when I get a newer version I guess. Thanks for the help though.
