Subject: collection property's items in inner tags
I have a control that I want to have put it's Settings collection property
as nested inner tags.
I thought I had put all the right attributes on the control, but it's not
saving the collection at all.
is there anything more I have to do beyond this stuff?
[
ProvideProperty("DefaultButton",typeof(Control)),
ParseChildren(true,"Settings"),
PersistChildren(false)
]
public class DefaultButtons : System.Web.UI.Control, IExtenderProvider {
...
[
Browsable(false),
DesignerSerializationVisibility(DesignerSerializationVisibility.Content),
PersistenceMode(PersistenceMode.InnerDefaultProperty)
]
public DefaultButtonSettingCollection Settings {
get {
return settings;
}
}
why isn't my control saving the Settings collection as nested inner tags?

I tried implementing your example in my control, and it is still not writing the collection to the page.
If you or anybody could take a look at my code, i'd really appreciate it.
the full project source is here:
http://www.metabuilders.com/betatools/defaultbuttons.zip
thanks for any help in this area. I really apprciate it.
