Disable copy(ctrl+c), paste(ctrl+v),cut(ctrl+x) in excel

问题

I have developed the vsto template in C# in which,i have added data validation for many fields in the excel sheet.If the user copy paste the content, those validations rules are overwrites and does not work. how can i restrict user to copy,paste,cut.**Is there any **other way to overcome this problem?

回答1:

Have you tried protecting the workbook ? Two ways to do the same

1.)manually

2.)programatically

回答2:

Following code should intercept Ctrl+V and effectively disable it

1.To disable the Paste Option(ctrl + v )

Application.OnKey("^v", "");

2.To enable the Paste Option(ctrl + v ) again

Application.OnKey("^v", Type.Missing);
