auto fire of items events on initilization (check/radio buttons)

[Brian Henry]

How can you stop the check changed event from fireing during the
initilization of a form? I have about 4 radio and check boxes on the form,
and when the form is initilizing, the one that is marked as checked during
the initilization (when InitializeComponent is called) always fires it's
check changed event, which I don't want it do to.. how can you prevent this?
thanks

Hi Brian,

I think we all do that with a flag/bool/switch whatever you name that, that
you set at the end of the load form event to true. This is the most wide
solution I've seen in this newsgroups for that.

I hope that helps?

Hi,

There is no way to prevent the event from happening. Here is a
possible work around.

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles CheckBox1.CheckedChanged

Static bIgnore As Boolean = True

If Not bIgnore Then

' Your code goes here

Debug.WriteLine("Checked changed")

End If

bIgnore = False

End Sub

Add the handler to the event after changing the state. Have a look at
the 'AddHandler' and 'RemoveHandler' keywords.
