using properties

[Jon Paal]

the primary use of a custom control is achieved with :

"<cc1:myCustomControl id="CustomControl1" runat="server" />"

properties are assigned programatically with a call to "LoadProperties(CustomControl1)"

Sub LoadProperties(oThis)
othis.Chart_align = "center"
...
End Sub


and this part works.


When I create a second instance of my custom crontrol, and try to access a single function of that control, it tells me the
properties don't exist.

how can I access a single function of my custom server control to return an interim value ?


.............. code start ...

'create a new instance of control
'-----------------------------------
Dim oDisplay as myCustomControl = New myCustomControl
call LoadProperties(oDisplay )

'create new arraylist
'--------------------------
Dim myArrayList As New ArrayList()

'populate arraylist
'-----------------------
myArrayList = oDisplay.buildarraylist()

............. end code .....

This fails because it's not accepting the properties, but it does accept them on the first instance above ??

------------- error msg -----------------
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Just a shot in the dark but what happens when you pass in the control
to LoadProperties() *by reference*.

found my problem, it was in the sequence of properties being passed.

thanks for replying.
