adding server controls at the client at run time

[z f]

hi, tough one? for me it is currently.

i have a user control that contains other controls like text boxes.

in the client i need to dynamically add the user control using DHTML.
i achive this by having the control hidden and grabbing it's innerHTML to a
new container in the HTML.
i also change controls ID suffix in order to be able to track added controls
like in old HTML.

for example txt_name_x_ becomes txt_name_1_.

now i need to instanciate the container control in the server after submit.

can this be done? without me having to get all the HTML submited internal
contained inputs of the control.

TIA!

ZF,

I'm not positive what you're looking for based on your post, but I have a
sample of reloading dynamic controls in order to access their values that
may help you to see. It's at:
http://www.aboutfortunate.com?page=codelibrary. Just search for dynamic
control and you'll see a few different samples. The one I think you'll be
most interested in is: "Reload dynamically created user controls in order to
use their viewstate".

in the sample you specified, you load the control, but the control gets its
"default" instance.
i need the control to "load" it's state from what is being submitted, and
being submited more than one instance.
so i need to differentiate the controls instances by their IDs.
is giving the newly loaded control the rqeuired ID will do the job?
i'm not sure.
the result should be something like is achived by a repeater that spawns
many instances of a control (in the <ItemTemplate>) to the client, and then
in the submit, even that it is not being binded again to the data, creates
the instances of the "spawned" control and creating them dynamically .

thanks

zf,

Did you also check out the "Dynamically add text boxes (or any web control)
to a page" sample?

It's doing what you are asking about.

ok thanks it looks good now.
the Controls.Add(ctl) line did the trick...

the problem i have now is getting the error
Control 'line_template_ctl1_x_' of type 'ComboBox' must be placed inside a
form tag with runat=server.
in the rendering stage.....
and i don't need the added controls to render at all.
it's just for the post processing.
after that all the page will be re-rendered
so i probably have to remove it unless you have other suggestion...
