SelectedDateChanged in RadDateTimePicker

[Jim]

I have  a  RadDateTimePicker in the web page,  the code below, when typing  date in  RadDateTimePicker. the event handler has been  fired, but when picking  up the date in calender. event handler not been fired ,

I don't know why?
Thanks

 

<telerik:RadDateTimePicker ID="formExten_AuthEndDate" runat="server"  AutoPostBack ="true" >

</telerik:RadDateTimePicker>

 

 

Private Sub formExten_AuthEndDate_SelectedDateChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs) Handles formExten_AuthEndDate.SelectedDateChanged
''''''''''

End Sub

Hi Jim,

SelectedDateChanged server event fires  when the user changes the value of the control, either when input area loses focus after the user has typed a new value, or when the user selects a new value in the popup calendar or time view control. Here is the sample code that I tried which worked as expected.
VB:

Private Sub formExten_AuthEndDate_SelectedDateChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs) Handles formExten_AuthEndDate.SelectedDateChanged
 Response.Write(e.NewDate.Value.ToString())
 End Sub

Thanks,
Princy.

Princy,
 Thanks. I think my function is same as yours . maybe ajax caused a problem. SelectedDateChanged server event fires only  input area loses focus after the user has typed a new value, event not fires when the user selects a new value in the popup calendar or time view control

Hi Jim,

I am afraid we are not able to replicate the issue locally. Could you reproduce this behavior with any of our demos?
http://demos.telerik.com/aspnet-ajax/calendar/examples/datetimepicker/autopostbackcontrol/defaultcs.aspx

Please provide us the exact steps to reproduce the issue or open a support ticket to send us a sample runnable application demonstrating the erratic behavior. Thus, we will be able to further analyze the problem and provide a proper solution.

Hello Jim,

The reason is that the default value of the AutoPostBackControl property is None:

http://www.telerik.com/help/aspnet-ajax/t_telerik_web_ui_calendar_autopostbackcontrol.html

I hope the clarification was helpful.

All the best,
