And what is the issue it?

What do you mean "by name or tag", exactly? Why using tags? Please clarify.
Most likely, this is just a bad idea leading to unsupportable code. You can always use member names, not property "Name", which you should not rely upon.

Hi,

Try this:

C#

IEnumerable<Button> buttons = this.Controls.OfType<Button>();
foreach (Button b in buttons)
{
      if (b.Name == "name" || b.Tag == "tag")
      {
          b.Enabled = false;
      }
}

If you've also containers on your form, such as Panels, then you should use recursion to disable also some buttons on the panel.

Hope this helps.

I up-voted this answer with my 4. Your naming for the button was somewhat confusing, so I clarified the code sample a bit. Would you mind? I usually show such simple code samples this way, and they are always understood correctly.

The problem is that OP's "name or tag" is confusing... Your answer is just the idea, which should be enough.
