I have a datagridview, in which one of the columns have real data. I want that this column to show the data look blurred when I release the project so that nobody can read this data. Can anyone help me on that.I would be grateful if you could illustrate with some code in vb.net 2010.

What I have tried:

1.I looked up the datagridview properties and functions.
2. ForeColor property of datagridview.

Why put the data in there if you don't want anyone to see it??

Its a sensitive data. And the form containing the data has to be published for demo purposes.

You have a few options:

1. Don't show the data in the first place. You have commented that the form containing the data has to be published for demo purposes but I contend that one column missing from the datagridview in the demo will not "break" it.

2. Obfuscate the column - I guess this is what you mean by "blurred text". As far as I know you would have to layer something over the data or use an unreadable font.

Both the above involve changing your software purely for the demo - that's a bit step and somewhat risky. A far better approach is ...

3. Don't use sensitive data for your demo! In many companies it is (quite rightly) forbidden to use genuine user information for testing and demonstrations. Have a copy database that has obfuscated data in it - either generated randomly or generated from real data (see this search for ideas on how to achieve that - Google[^] - I don't have any recommendations which is why I've posted the search results rather than a single article, although I did find this on CodeProject Strings Obfuscation System[^]
