Does ASP.NET require ActiveX or not?

Is Asp.Net required to activate Ajax ActiveX? I suspect this is happening, because without the "initialize and script ActiveX controls are not marked as safe" setting, ASP.NET UpdatePanels do not work in IE settings. Am I right?

Very important change here

I had no doubt about IE6. But I was able to reproduce this even on IE8 (Windows 7). Try setting IE security to high. After that, you will need to install:

  • Initialize and script ActiveX controls are not marked as safe
  • Send data without an encrypted form
  • Active scripting

to be able to use the Asp.NET UpdatePanel. The last two are fine, but the first ... I remind you that this is IE8

You get this error because scripts access an object XMLHttpRequest(for AJAX requests) that was implemented through ActiveX in earlier versions of IE.

Since he even checks it, you get this warning. No, this is not required for ASP.Net, but you may have problems with partial reverse processing in early versions of IE if it is disabled.

Using the .NET Page Class http://msdn.microsoft.com/en-us/library/ms178138.aspx You can make more standardized AJAX calls using JSON. But you need to learn AJAX for this.
