tag = only property.get gets called

[Sam]

I've got:
<ParseChildren(True)> _
Public Class UserElement
Inherits WebControl

Public strLabel As new Label

Public Sub New()
strLabel.id = "myID"
End Sub

<PersistenceMode(PersistenceMode.InnerProperty)> _
Public Property objLabel() As Label
Get
Return Me.strLabel
End Get
Set(ByVal value As Label)
me.strLabel = value
End Set

When calling:
<objLabel runat="server">mySecondLabel</objLabel>


I've noticed that only objLabel.set() gets called.
Which means the <objLabel> creates a "new" Label object.
So when the objLabel.set() gets called my old properties like ID (as set
in New()) get overwritten (with nothing, because not set in the tag).
Is there a way that ASP.NET first calles the objLabel.get() and then
"adds" the properties to this existing object?

The other option would be to copy all the properties by hand which is
quite ugly.


Sam.

Hi,

not sure what you are trying to do besides exposing the Label but as the
Label is instantiated within the control, only get part of the property
makes sense. It returns a reference to the object and that reference can be
used to modify properties of the contained Label. therefore set part doesn't
make sense, because you don't want to reassign the reference, right?

E.g

<PersistenceMode(PersistenceMode.InnerProperty)> _
Public ReadOnly Property objLabel() As Label
Get
Return Me.strLabel
End Get
End Property

This is essentially what you mean by "Is there a way that ASP.NET first
calles the objLabel.get() and then
adds" the properties to this existing object?" as the returned reference is
only needed to modify the contained Label.
