Hello, everybody,
I'm having a problem creating a control...All I want to do is a simple poll
system, so I need to input (trough a ListitemCollection) the values from the
user.
The problem is I'm getting an error each time I try to modify the elements,
I don't know why....
If anyone can help, I would appreciate...
Raphaël...

Hi,
:)I didn't see your code.
I think you may add ListItem to controls and a ListItemCollection instance
in CreateChildControls method .
like:
private lstCol As New ListItemCollection
sub CreateChildControls
Dim lst As ListItem
lst = New ListItem("ASP.NET", 0)
controls.add(1st)
lstCol.Add(lst)
lst = New ListItem("ASP", 0)
controls.add(1st)
lstCol.Add(lst)
end sub
If you'd like to create a listcontrol ,you can inherit
System.Web.UI.WebControls.ListControl.
