When I click a button I don't want the click event to fire. Is this
possible?
In fact, what I would really like is to be able to intercept the click
event, perform some action, and then prevent the click from passing through
to the button.
Any help or suggestions much appreciated.

Why don't you just remove or condition the code from the Click event?
The button will do nothing by itself.

Hi Klaus
I actually have a lot of buttons, and text boxes, and dropdowns, and so on
that I want to do this for. To condition the code in every single one would
be tedious and repetitive.
I am really looking for the principle so that I can apply it to other types
of control as well. For example, I also want to prevent a dropdown from
dropping down, and prevent the button from appearing depressed when it is
clicked. In a nutshell, I want the control to behave like it never got the
click / mouse down event.

Well that's possible, you can simply inherit from the control itself and
make it do anything you want.
For example, you could put some code in the OnClick method and so your stuff
there and prevent things from bubbling up to the container.
But that assumes that you started there - it's going to be hard to retrofit
to your existing code, especially if you have a lot of it.

Hi Charles,
Seems like you want to create your own Control-Classes.
Do something like:
Namespace Law
Public Class myButton
Inherits System.Windows.Forms.Button
' Add your code
Namespace Law
Public Class myComboBox
Inherits System.Windows.Forms.ComboBox
' Add your code
Of course you have to fill in the details yourself, use attirbutes, etc.....

No. If there's an event handler, the event will fire.
In fact, what I would really like is to be able to intercept the click event, perform some action, and then prevent the click from passing
through to the button.
The click can "pass through" to the button all day long and nothing will
happen other than it will appear pressed and then unpressed. That's all the
button will do on its own. If you don't want YOUR CODE executed when a Click
event occurs, write more code to detect this condition and then simply DON'T
EXECUTE your code.

Then you can use this button instead of the standard Windows Forms
button. One possible extension would be to provide a 'BeforeClick'
event that passes in a 'BeforeClickEventArgs' object that provides a
'Cancel' property. If the event is handled and 'Cancel' is set to
'True', the 'Click' event would not be raised.
The code above will extend the standard button with a 'Clickable'

Thanks again Klaus.
Along with the other responses, I think everyone is pointing in the same
direction: basically, I have to create my own control and inherit from
button, etc. As you suggest, though, I'm not starting from there, and retro
fitting is not really an option.
Ho hum.

Hi Jeff
As I mentioned, I have a lot of controls already, and retro-fitting
conditional code will be problematic. I even favour the inheritance route at
this stage, but I'm not happy.

Hi Herfried
I was beginning to think I had become invisible. I seem to have a lot of
posts unanswered at the moment - I don't suppose you would care to take a

Anyway, back to the point. A good solution if I had started from there, but
as you may have gathered from my other replies, I haven't.
I wonder how the IDE does it, or SharpDevelop, for that matter. I have
looked at their code but I will never find it in there; there's loads of it.
There must be a way, surely, of intercepting the mouse events, or by using
an API?

Charles,
Have you considered placing a window (control) over the top of your control
that shows the original control, but this second control eats all the mouse
clicks?
Unfortunately I don't have a good .NET example of how to do this, maybe a
Transparent or opaque control will do it...
Hope this helps

Hi Jay
Yes, I had as it happens, but we all know how good GDI+ is at doing
transparent. ;-)
I think that this is by far the best solution because it takes care of
absolutely everything underneath by masking it. If only there was a control
that I could use, that would show the stuff below, but, as you say, eat the
mouse clicks.
Do you have one in mind?

Charles,
As I stated I do not have an example!
The closest I think of is to create a form and change the Form.Opacity value
to 0. Place this second form over the first, this second form will get all
the mouse clicks...
However as I stated I DO NOT have an working example!
Ideally you want a control that does not paint ANYTHING, so the window below
it shows through...

It's a good solution for this problem, however if you want to draw in the
window so as to make some parts Opaque or Semi Transparent, then you'll find
that there is a problem with zOrder painting, which is why I usually create
Shaped controls.

I have done something similar with a combo box that I wanted to extend.
It is pretty easy to search and replace the variable declaration and
instance instantiation lines in the code. You could add a property like
Clickable with a default value of false, etc, and then when you want to
make all your buttons unclickable cycle through them and set their
Clickable property to false. It didn't end up being too bad for my
case.

Hi Michael
I have settled on the idea from Herfried. Putting a transparent window in
front of my control does the trick. It is even easier as all my controls
inherit from my base control, so I only have to implement it in the base
class for it to work.
Thanks again.
