On the following link
I attach a small video which demonstrates the example on my side. However, it works as expected.
Also I am using the default IE security settings. The size of the excel document which I use is 7 rows x 6 columns, 9KB.
Additionally could you please try using the RadAjaxPanel or asp:UpdatePanel instead of RadAjaxManager and let me know if the issue still persists.
Looking forward for your reply.
