Hello,

When i have AutoPostback = true the selectedIndex chnaged event is fired correctly. But i do not want to have postback. But when i remove (AutoPostback = true) event do not fires. Could you please help me how both to hire this event and not to have a postback?

Thanks for your time.

<radAjaxC:RadComboBox ID="radComboAdressLine1" runat="server" Width="248px"

 

 

AllowCustomText="True" ShowToggleImage="false" ShowMoreResultsBox="false" Skin="Outlook"

 

 

EnableLoadOnDemand="True" MarkFirstMatch="True"

 

 

OnItemsRequested="radComboAdressLine1_ItemsRequested"

 

 

AutoPostBack = "true"

 

 

onselectedindexchanged="radComboAdressLine1_SelectedIndexChanged"

 

 

CausesValidation="false"

 

 

MaxLength="34"

Hello Alexey,

Actually this is expected behavior of RadComboBox. You can set AutoPostBack property to false and postback from a different control, asp button for example, to fire the selectedIndexChanged event.

Thanks a lot,

But what i need is not to have any postbacks on the page. I want it to be ajax based at all.
But also  i want to do some server code when the selected index is changed. I tried to do that in selectedchanged event handler but the event is not hired.

The question is How to do that server code ajax-based without a postback? 
Do you have some ajax based example how to do that?

Hello Alexey,

I suggest you use RadAjaxPanel in your case. You can check our online example here.
