Hi Greg(ory),
You're right that according to the code below, you won't get any list
items without a selected value... which you won't get on
Response.Redirectunless you're using EasyListBox with CookieMemory
turned on. You could get
around this by leaving a "Case Else" in there, but it sounds like you're in
the middle of a population when that happens.
How about this? In your dropdown's OnSelectedIndexChanged event handler
sub (server-side), you can send some Javascript back to focus on it, like
this:
Page.RegisterStartupScript("gotoDDL", "<script language='javascript'>
document.getElementById('" & myDDL.ClientID & "').focus();</scr" & "ipt>")
(that last concatenation is because a closing script tag in single-page mode
will confuse the parser)
Of course if you want to avoid postbacks to populate your lists, you
could roll your own client-side solution (see
http://easylistbox.com/listBoxResources.aspx ) or you might consider ELB (
http://easylistbox.com/demoRelated.aspx?rl=af ) as a possible alternative.
HTH,
Peter
