Need custom collection to databind

I'm in a jam here. I need to make my own collection of customers to simplify
the inteface (don't want Add, CopyTo, Contains and so on - need a nice clean
interface). I can do this by NOT inherit from
Collections.Obj ectModel.Collec tion(Of Customer) and do this instead:

Public Class Customers
Private lst As New Collections.Gen eric.List(Of Customer)
End Class

And then add my own methods (private Add, Public Count and so on) to work
with lst. That makes me in control over the final interface...

The problem is however is that the class can't be used with foreach and
databinding. So I figured - I'll implement Generic.IList(O f Customer) and
hide the methods (making them private) I don't need - and accept having a
GetEnumerator-method on the interface. Now I can use foreach - great - but i
still can't databind?? The Exception is "Complex DataBinding accepts as a
data source either an IList or an IListSource.", and I don't understand
this. I implemented IList but the exception says that my object is not a
IList ???

Can anyboby give me a clue or explain what's going on?

Thanks

I am having a hard time with setting a property on a custom server control that i am placing in a repeater. The control inherits from DropDownList. The property is being set in the repeater using the DataBinder.Eval method. I can write that value out to the screen, however, it is not available to the control. I think it is a problem with the databinding of the repeater making data available to the custom control too late. Below is a...

Hi there, I have a typesafe collection in my application called Countries, which is derived from the ReadOnlyCollectionBase. As you might guess, the item-value is of type Country.

I have a custom collection which contains instances of a custom class. With me so far? OK, now I set the datasource of a combobox to the collection, having overridden the ToString() function of the custom class to return one of its text properties. Life is good. The first of two problems involves the combobox showing the first item in the collection. To get around this,

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
