Dynamically added controls and events

[Paul]

An early Happy Thanksgiving to you and yours...

We develop data driven apps. We dynamically place controls on a panel which
may be then be placed on a web form or another control. My problem is that I
can't get the events of the hosted controls to fire.

e.g.
' myUserControl.ascx. is placed on myWebForm.aspx in the Designer
' myUserControl.ascx has a Panel on it, Panel1
' From code in myUserControl.ascx I pass Panel1 ByRef to a class with a
public sub which adds controls and events to the panel based on it's unique
identifier

When myWebForms.aspx presents the events will not fire. How can I accomplish
this? TIA

In order to get the events for dynamically added controls, you need to
make sure they are added to the form in the exact same order on every
post back. This means if you add a control, then remove it, then add
another, you will have to do that exact same sequence again the next
time the page is built.

Last night someone posted a link to this:

This looks to simplify the issues involved with dynamic controls and
their events by providing a control that handles it all for you. Look
into it, it looks pretty good (though I haven't tried it yet).

Have A Better One!
