                                    Since the July release of Windows/Office updates we now get a message when loading an xls file generated by the DevExpress grid export code

                                    In Excel 2007 the message says "Office file Validation detected a problem while trying to open this file. Opening it may be dangerous"

                                    In Excel 2010 the message says "Excel has detected a problem with this file. Opening it may be dangerous. You should not open this file unless you trust it"

                                    Is there a fix for this yet?

                                    I am assuming that Microsoft have done something to detect when a file has been created with Excel and any file that has not been created using Excel would generate this message

                                    Whilst it does allow the file to be opened, it is annoying for users

                                    I have attached a file as an example



                                I believe that this is the change that has caused this problem




                                I have reproduced the issue with your XLS file, but I cannot reproduce it with the file generated by my sample project.
                                Please modify our sample or provide your project, so that we can reproduce this issue on our side.



                                Thanks I believe this is due to another third party component we use
