Linkbutton becomes invalid due to local security settings.

A few days ago, run a previously written aspx ProgramThe linkbutton is unavailable. Click CodeUnable to execute, really dizzy, good before.
It's strange to switch to a button for execution. I always thought that the functions of the linkbutton and the button are the same.
Later, when I checked the IE Security Settings, I found that the local security level was at the highest position. I didn't call back the last time I tested IE Security. It's really true. Set it to the default level and test linkbutton again. It can be executed!

In addition, I also found that when the local Intranet security is set to the highest level, ASP. NET debugging (F5) cannot be started, and the error prompt is "You are not authorized to debug this server. Verify that you are a member of the "Debugger users" group on the server. "()

However, you can skip debugging and execute Ctrl + F5.

The solution is to reduce the security settings of the Local intranet, set it to the default level, and then re-open Visual Studio.

This problem is also common. At least I have seen some people ask questions, so I will explain it here and hope they can find a solution through Google.
