I am not completely sure what scenario you are trying to implement. Would you elaborate more on what are your requirements and what should be the expected result? It seems that you are firing an Ajax request on document.ready(). Why do you need to call ajaxRequest() on that event? Having better understanding of your scenario would allow us to provide proper suggestions on how it could be achieved.
On a side note in the code you provided it seems that some controls are Ajax-ified with RadAjaxManager and RadAjaxPanel at the same time. It is highly recommended to avoid this as stated in this article
Additionally the ClientIDMode is set to static for some of the controls. This mode should not be used with our controls, especially when they are Ajax-ified, as it could lead to unexpected results. It is recommended to use ClientIDMode set to AutoID. More information on the subject is available in this troubleshooting article
Moreover I would suggest taking a look at this article
related to using RadWindow with Ajax.
