I have created a webpart. However it keeps complain that I have not "registered as safe":

"UnsafeControlException: A Web Part or Web Form Control on this Page cannot be displayed or imported." "could not be found or it is not registered as safe."

Here is manual fix:

I edit this file: C:\inetpub\wwwroot\wss\VirtualDirectories\80\web.config

and I add this:

<SafeControl Assembly="ExampleWebPart, Version=1.0.0.0, Culture=neutral, PublicKeyToken=9d97efbc93164680" Namespace="Example_Web_Parts.VisualWebPart1" TypeName="*" Safe="True" SafeAgainstScript="False" />

However, how I can do this through Visual Studio? It stupid always manully add this to web.config file.

How to: Mark Controls as Safe Controls

  • Select the web part folder for which you want to change the safe control entries in web.config file.
  • Press F4 to open properties window
  • In properties windows there is last entry of properties displaying as Safe Control Entries
  • Click on the eclipse sign in front of Safe Control Entries value.
  • Inside “Safe Control Entries” pop up window, check for Namespace properties inside SafeControlEntry1 properties panel.
  • Change value of namespace property according to your namespace and class and click ok.
  • Save and build the solution and deploy it again.

Now after successful deployment check web.config of site and voilà you’ll find the correct safe type entries of your web part.
