[Solved] Unable to get value of the property 'ajaxRequestWithTarget'

[Kris]

We have recently upgraded from version 2008 to 2012 and now it start showing following error: 

Microsoft JScript runtime error: Unable to get value of the property 'ajaxRequestWithTarget': object is null or undefined


it is happening at the following line :
<%= radajaxpanel.ClientID %>.ajaxRequestWithTarget('<%= radajaxpanel.UniqueID %>', eventArgs.get_item().get_value())

Is it because ajaxRequestWithTarget is no longer supported by radAjaxPanel ? Thanks in advance.

Hi Kris,

The ajaxRequestWithTarget client method properly works for RadAjaxPanel however you should add a correct eventTarget and not the RadAjaxPanel itself. You could add a control which is added in the RadAjaxPanel as event target. If you need to perform Ajax through the RadAjaxPanel itself you could directly use ajaxRequest method. See the help topic below:

Thanks for your reply, Actually I have an embedded ajaxpanel inside the outerajaxpanel. Can I add embedded radajaxpanel as the event target ? Something like : 

<%=OuterAjaxPanel.UniqueID %>.ajaxRequestWithTarget("<%=embeddedAjaxPanel.UniqueID %>", item.get_text());

Hi Khris,

Actually using nested AjaxPanel is not recommended approach and we suggest our customer to avid such scenarios. You could simply replace the inner AjaxPanel with regular asp Panel and use it as ajax target.
