@ design time or @ runtime ?

[Janiek Buysrogge]

Hi,

Is there any kind of check like

#if DESIGNER
...
#endif

I don't want my control's OnLoad code to execute whan I drag it onto a
parent container, only when I run the application.

Thanks,

JB

Janiek,
Yes there is (it escapes me for the moment), there's something in the
System.ComponentModel.Design namespace (i think!) that you can check. I
assume you mean behavior like the fact a listbox displays it's name
only in design mode.

Hope that points you in the right direction,
James

There is a protected property on System.ComponentModel.Component called
DesignMode, which returns true if the component is currently in design
mode. I assume your component derives from this class, so you'll be
able to access it directly in your OnLoad method.

Hi Janiek,

you can use the DesignMode property of your control or form (or any
Component).
But it doesn't work in the constructor of the Component!

Works like a charm...

Thx for the quick feedback guys.
