Composite control - sub control as a property not rendering

[Bob Jones]

I can't get the text property of this label control I am exposing to
update in the designer (when I cange the label's text property) or
when rendered on a web page. However, if I cange the font property of
the label control it updates everthing! I know I am doing something
stupid-wrong. Anyone help?


public class SDNetLabelTextBox : ContainerBase,
ICompositeControlDesignerAccessor, ISDNetControl
{
private Label _label;


public SDNetLabelTextBox()
{
this._label = new Label();
this._label.ID += "_SDLabel";
this._label.Text = "SDNet LabelTextBox";
}


public override void RenderControl(HtmlTextWriter writer)
{
this._label.RenderControl(writer);
base.RenderControl(writer);
}


public Label Label
{
get { return this._label; }
set { this._label = value; }
}

#region ICompositeControlDesignerAccessor Members

void ICompositeControlDesignerAccessor.RecreateChildControls()
{
base.ChildControlsCreated = false;
EnsureChildControls();
}

#endregion

So, nobody has any idea why this doesn't work?

Ok.. here is what I have found to work so far...

If I create a custom control and derive it from a base web control and
then add the [NotifyParentProperty(true)] attribute to the overriden
property I want to update in the designer (e.g. Text property of the
label) and use my custom control instead of the standard control.
Everything updates for the property.

public class SDNetLabel : Label
{
[NotifyParentProperty(true)]
public override string Text
{
get
{
return base.Text;
}
set
{
base.Text = value;
}
}

[NotifyParentProperty(true)]
public override System.Drawing.Color ForeColor
{
get
{
return base.ForeColor;
}
set
{
base.ForeColor = value;
}
}
}

Is there a property or attribute that can be specified on the web
controls to make them always update the parent when a property changes
or am I stuck writing derived controls just to set an attribute on the
properties I want updated via the designer?
