Hi,
You must have some error, if you do not post your code it's useless.
Ijust did a fast test, I created a form, put a panel, and inside it a
numericupdown, I set the panel as disabled.
also added a button withi this code:
this.numericupdown1.Value = 12;
IT DOES FIRE the event.
Below you will find my full code listing, I left it just as VS generated
it, for you to see it visually.
Cheers,

How much of an error can I have when I do a NumericUpDown.Value =
someValue; and the subscriber isnt getting it.
Im quite sure Im setting the .Value property and I am subscribed to the
ValueChanged event.
Could you explain where the error is and no im not giving out this
production code. Could be an issue with my version installed. I always
hated mishmashed upgrading scenarios.
In the InitializeComponent() form designer code its clearly subscribed my
event handler to the event.
When I start the form, its set the panel to enabled = false (from the
designer property) and I load up the value and set the .Value property,
its clearly NOT firing. I set a breakpoint and nope, nada.
I now call the event handler directly after setting the .Value property as
a workaround.

must be an error in your code.

news:Ow**************@TK2MSFTNGP12.phx.gbl... Is that the desired logical behaviour because I am updating a value , its logically changed but yet its not notified to all subscribers that its
changed. Doesnt smell right to me.
