Hi,

I have a problem with changing properties of a third-party control at
design time when the control is encapsulated into my own user control.

I have a third-party control (TPControl) that allows me to change
properties at design time. I mean, if the control is dropped on a form
and some properties are changed in PropertyGrid atg design time all the
changes are persistent (some code lines are generated).

Different result when I use this control encapsulated into my
UserControl.
I create my own UserControl (MyUC) and encapsulate this third-party
control in my UserControl (by dropping it on UserControl). I manually
create a property that exposes this third-party control.

private TPControl tpControl;
public TPControl TheTPControl
{
get
{
    return tpControl;
}
}

I drop my UserControl on a form.
When I open PropertyGrid for my UserControl being set on a form I can
expand the property item (TheTPControl), which is responsible for
third-party control. PropertyGrid allows me to change any value for
that third-party control, but these changes are not persistent. I mean,
after project is rebuild all the changes are lost, no code lines are
generated.

Any ideas?

Thank you,
Alex Zhitlenok
