Does anyone know why there is a dialog box to ask me to "open, save, cancel" when opening a excel file which generated from an aspx page? Why when open a pdf file, the IE will not show this dialog box but open it in the brower?
I want the the excel to be openned in the IE broswer automatically without showing the dialog box. I have MS excel installed and I have checked "Browse in same window" in Windows Explore -> Folder Options -> File Types -> XLS.
What else I have to do?
