'' Could not be set on property 'Items' - Error

[Murray]

Sorry if this is not the correct group i could not see one for web controls

Hello

I am trying to write a cutom web control, The control contains a customer
collection that i want to use the Collection Editor in properties to add
members to this collection.

In design mode the control works correctly but when i run the application
the control in the designer swaps to a "Error creating Control" gray box,
but it seems to display correctly in the web browser

Im fairly new to this so not sure what people would like to see to help me -
but shout and i send something

Thanks in advance,

I have foud the problem it was due to the Items property being read/write

so the property definition should be

<DesignerSerializationVisibility(DesignerSerializationVisibility.Content), _
PersistenceMode(PersistenceMode.InnerProperty), _
Bindable(True), Category("Appearance")> ReadOnly Property Items() As
TableDef.ItemsCol
Get
Return mobjTable.Items
End Get
End Property

Here is a web control property
<Bindable(True), Category("PROPERTY CATEGORY"), DefaultValue("")> Property
[NAME]() As Integer
Get
Return NAME
End Get
Set(ByVal Value As Integer)
NAME = Value
End Set
End Property
