[c#] A potentially dangerous Request.Form value was detected from the client

I see there's a lot written about this...and I didn't see this mentioned. This has been available since .NET Framework 4.5

The ValidateRequestMode setting for a control is a great option. This way the other controls on the page are still protected. No web.config changes needed.

 protected void Page_Load(object sender, EventArgs e)
 {
     txtMachKey.ValidateRequestMode = ValidateRequestMode.Disabled;
 }
