I really wonder why do you make this control called
"RadAjaxPanel" it really bad one, the normal ajax update panel is one
hundred time better than yours, after spending weeks in doing some aspx
pages with the "RadAjaxPanel" I found that the "asp:UpdatePanel" did it
for me just like that. your control really need too much improvement and
reliability assurance. I sorry to tell you that I don't recommend your
item at all.
