One item dropdowns

[Jon]

I am using cascading dropdowns, where one dropdown determines the data in
the next, etc...

If a dropdown has only one item in it, the SelectedIndexCh anged event is
never fired, even if you click on the dropdown and "reselect" the single
item. This also happens when there are multiple items in the DD with the
first item. You have to select another list item, then reselect the first
one to have the event fire. I have it set to AutoPostBack, but obviously it
is not in these situations. Is there a way to make the event happen in
these situations.

I tried the following (thinking it would force the user to select the item
and fire the event), but it still selected the single item.

ddTest.DataBind ()
ddTest.Selected Index = -1

Thanks

Try adding a "-- Select Item --" item to the top of the list. That way,
selecting even the only ONE (other) item in the dropdown causes a
selectedIndex changed event.

Thanks. Not the solution I was hoping for, but it certainly works.

Just thinking about this. Forgive me if this is a silly idea, but here goes.
I get the impression that you don't want the "-- Select Item --" to show in
the dropdown list. I would suggest including it as suggested, but setting
the style atrribute to "visibility : hidden; height:0; width:0"
