Designer serialization

Hi,

When I drop ChildFormDialog control on form, it will "auto generate code below at designer.cs.

[codesnippet]This.ChildFormDialog1.ParentForm = this;[/codesnippet]

For curiousity, I created a class to "subclass" ChildFormDialog component using association which able to drop on usercontrol..
I would like to auto generate code below when drop to user control.

[codesnippet]This.ChildFormDialog.ParentForm = this.ParentForm;[/codesnippet]

However, It doesnt't work. It always give me code below.

[codesnippet]This.ChildFormDialog.ParentForm = null;[/codesnippet]

How to do this?

My Current Code
[codesnippet]
[Browsable(false)]
public BaseForm ParentForm
{
get
{
if (_ParentForm == null && this.DesignMode)
{
IDesignerHost loDesigner = (IDesignerHost)this.GetService(typeof(IDesignerHost));

if (loDesigner != null)
{
if (!loDesigner.RootComponent.GetType().IsSubclassOf(typeof(MicroFour.StrataFrame.UI.Windows.Forms.UserControl))
&& loDesigner.RootComponent != this)
{
return _ChildFormDialog.ParentForm;
}
else
{
MicroFour.StrataFrame.UI.Windows.Forms.UserControl loUC = (MicroFour.StrataFrame.UI.Windows.Forms.UserControl)loDesigner.RootComponent;
return (BaseForm)loUC.ParentForm;
}
}
}

return this._ChildFormDialog.ParentForm;
}
set
{
_ParentForm = (BaseForm)value;
this._ChildFormDialog.ParentForm = (BaseForm)value;
}
}

Chan,

This goes beyond a simple post or reply. You are getting into serialization within the designer which takes a good amount of explanation.

You have to define the this when the control is dropped. Since you have purchased StrataFrame, you also have the source code for reference purposes. I recommend looking at the UserControl object and then looking at the SyncObject property. This will at least get you started.
