Change app_themes dynamically

Question

I want to give my admin user the ability to change the app_themes value in the web.config dynamically, using a asp:dropbox. I have seen websites and samples in the web that allows the user to change the theme at run-time. These samples doesn't update the web.config theme value and I want my admin (office boss) to be in control of this.

Is there a way to:

1. Get all folder names to display them in a dropbox?
2. Update the web.config app_themes value with the selected value in the dropbox?

Answer 1

I believe this should allow you to edit the web config file

Change a web.config programmatically with C# (.NET)

And to get a list of all folder names in a directory to put in a dropbox:
