Hi John

There is an easier way to read and write to the UserControl TextBox
from the host page.

In the VB code for the UserControl itself decare a text property and
link it to the text of the actual control e.g.

public property TheText() as String
     Get
           return textbox1.text
     End Get
     Set (ByVal value as string)
           textbox1.text = value
     End Set
End Property

The content of textbox1 will then be accessible as LTUC.TheText
(It will also appear in the property window of the declared instance
in VS designer and also in the html source code editor as a
recognizable attribute!)

Assuming LTUC is declarative (i.e. declared at design time rather than
programmatically like MyUC) then LTUC.TheText will be preserved by
ViewState because textbox1 in the UserControl is itself declarative.
