Hi,

Any dynamic ASP.NET control must be recreated for each request to handle events,
It is ASP.NET requirement

I suggest to use DirectMethod for dynamic controls

When you say to use DirectMethod for dynamic controls, what, specifically, do you mean?

Hi @jmcantrell,

Vladimir meant that DirectMethod doesn't require a control instance like DirectEvent.

For example, if you need to render a Button dynamically and a server side Click handler, then, commonly, you have two approaches:

1. A Click DirectEvent + recreating the Button control each request.

or

2. A Click listener + a DirectMethod.

an example of this?

dynamically created button in dynamically created panel

my case having
portal<-real in markups[
i portal column <- dynamic[
j portlet <- dynamic[
k button <-dynamic]
]
]
]
button event[ show hidden window and pass button.text value to this window];
I would be so glad i would jump an whole minute in happiness
