I am creating (in VB) a web app that populates a Directory Tree from a
supplied directory on the server. I simply want to click the name of the
file and have the program pull that into a text field, but no dynamically
created onClick event seems to work for me. I have tried <span> tags,
buttons, and literals, but seem to have no luck. Can anyone help me?

I have the same or similar problem. From a listbox click I dynamically
create some labels, related text boxes and an OK button. Then I hook up
the button's click event. However, the event never fires. When I did the
dynamic stuff inside Page_Load the event fired but I need these as
separate subs and that is not working. Please let me know if you find a
solution. I'll do likewise.

Morgan,
This site
http://www.dotnet247.com/247reference/msgs/3/17094.aspx
has 2 variations to the solution. The declaration of the control and its
event wiring is done either in Page_Load or Page_Init event. One writer
says
"NB The control has to be re-created when the post backs is done or
else the event will not fire. I suggest creating the control within
the Page_Init event."
Hope this helped.

I think your control needs to implement IPostBackEventHandler which
requires you implement LoadPostData(...) and RaisePostDataChangedEvent().
When you dynamically add the control to the page, also
Page.RequiresPostBackEvent(theControl) as well. Let me know if this works.

Chuck,
My VS.NET has become corrupted and I'm having problems reinstalling. When I
do reinstall I'll try out your suggestion.
Thanks,
David
