How to embed one control within another?

[Sky]

What I have currently:
I have a user control called mod_container.a spx that is basically two
divs -- the top a toolbar, that expands/collapse the second div which can
contain other modules/controls (eg a newsfeed, quick phonelist, login, etc.)

But the controls end up too 'deep': it appears that it would be
lighter/better if I could just enherit the uc_login.aspx directly off of the
uc_container.as px so that all modules have the same look/feel in terms of
perimeter...

But -- and my question -- if you enherit one user control from another the
first uc_controls html is never used -- it just reads the second/descendants
html...and therefore, no container wrapper html appears...

How would I do this?

One direction I've looked is to somehow take the uc_login.aspx's html, and
before rendering it, somehow inject above it the html of the container (the
two divs...) and then moveNode(deep) the whole original structure into
it....
Sounds heavy and not clean so am suspicious of it... Secondly -- I only
found a way to get a handle on sub-controls...not plain old html elements.
Any ideas?

Hi,

you are trying to implement visual inheritance which isn't support by
ASP.NET. but, you still can create your own base class that inherit from
UserControl, override the render method and add HTML. every usercontrol
that will inherit from your UserControl will embed the base usercontrol
class HTML.

public class MyUserControl : System.Web.UI.U serControl
{
public MyUserControl() : base()
{
//
// TODO: Add constructor logic here
//
}
protected override void Render(System.W eb.UI.HtmlTextW riter writer)
{
writer.Write("< b> Base Class Text </b>");
base.Render (writer);
}

}

Dear Natty:
Thanks for the answer -- I think I see what you are getting at -- but for
verification -- at what point does the Render() function draw it's sub
Controls, and can this be controlled?

In other words how do I ensure this behaviour:
protected override void Render(System.W eb.UI.HtmlTextW riter writer)
{
writer.Write("< div id=OuterDiv>");
writer.Write("< div id=Header>My Container Header</div>");
writer.Write("< div id=Stuff>");
//-------------------------------------------------
//Now render all sub controls within this second div...
//Does one loop through it's children like this:
//[bad proxycode but I hope you see what I mean]
while (i=0;i<this.Con trols.length;i+ +){this.Control s[i].Render();}
//-------------------------------------------------
writer.Write("</div>");
writer.Write("</div>");
base.Render (writer);
}
An important point: this manual manipulation of controls -- does it wig out
the Control tree so that click events stop working, and viewstate gives up?
I've seen that
happen in my forays -- can't remember what caused it -- but it seems that
sometimes if you manipulate the Control tree too hard, MS can't figure out
what control is what
and stops tracking it -- or gives errors.
Oh! Did you see my previous question in this thread just before this one?
I've tried to make enherited controls -- I've made one user control called
'base' and then
a second one that enherits from it in the *.cs file -- and it holds together
at run time. But ever time I try to open and close the second usercontrol is
states that it can't find
all the pieces... ever seen such behaviour and know the cause/solution?

Hi again,

Yes you can achieve it. but you need to use Controls Addat method to
place your code in front of the derived control code :

protected override void Render(System.W eb.UI.HtmlTextW riter writer)
{
System.Web.UI.H tmlControls.Htm lGenericControl oGen = new
System.Web.UI.H tmlControls.Htm lGenericControl ();
oGen.InnerHtml = "Start <br/>";
this.Controls.A ddAt(0,oGen);

// the control data will render here

base.Render (writer);
writer.Write("< br/><b> End Base Class Text </b>");

}
2) I don't see any reason for server side events to stop working.

3) I try it out on my machine (VS 2003) and it working.

Dear Natty:
Uh...still missing that "little something before it goes Click! in the
brain....(I might need to change my coffee brand!)

a) I have an *.cs base class that is called uc_mod_containe r.cs The ascx
part of the file is never going to be used so any html I put here with the
IDE will be never seen. That I get. So we will be doing the HTML stuff in
it's Render() event. Get that, I think.

b) I have a *.cs enherited class that is called uc_mod_phonelis t.aspx that
we want to be a standalone app that can be wrapped by different wrappers
(therefore enherit from different uc_mod_containe r.cs depending on
project)...

d) Because uc_mod_phonelis t.aspx does not have an explicit Render() command
it reverts to base.Render() (the uc_mod_containe r.cs) which starts drawing
divs everywhere -- and then injects the controls into it.

In other words:
uc_mod_phonelis t.aspx would have already content that looks (proxy) like:

<div><hr/><br/><datagrid runat=server/><etc.><other simple html tags that
are not controls....></div>

and we have to wrap it all up so that the final output looks like

<div id=outer><div id=header>Click here to expand/collapse second
div</div><div>{all the html and controls shown above}</div></div>
BUT (and my question):
The code you demonstrated would inject any SubControls we may have injected
into uc_phonelist (as I see it only the datagrid qualifies as a
control)...this doesn't address the HTML that's already there and that we
already put into the uc_phonelist.as px via the IDE. Or does it? These html
elements are not Controls, but are just [what?]. Plus they already there, so
AddAt would duplicate them if we doing something like that, right?

Second nagging question: If uc2 is enherited from uc1 -- so they are the
SAME control, no? SubControl of uc1 is NOT uc2? Correct?
Sorry for being such a gormless twit/slowwwww at understanding this
morning...
but don't give up on me: your help is really invaluable, and I'm pretty sure
we are nearly there...

Best,
Sky

Hi Natty:
Was able to analyse your code, and I do understand the notion of injecting
prefix and suffix code around the base.Render(wri ter); statement.

But that -- although simple enough to accomplish -- completly destroys any
chance of injecting working buttons above and below.

What I am saying is that what I would like to accomplish is the following:

writer.Write("< div stuff above the enherited controls/><asp:button
runat=server onClick=ClickMe ......./>");
base.Render(wri ter);
writer.Write("< asp:button runat=server... ../></div>");

but obviously since these were injected after InstantiateCont rols(), they
are completly 'dead'.
They appear as buttons (maybe) but have never been delegated back to the
forms attached ClickMe1() event...
Parts of the puzzle that I have figured out to doing this include the
following steps...

Create and instantiate controls dynamically within the OnInit() event so
that later InstantiateCont rols() wires them up correctly to be
parts of the webform's visualstate,etc . wiring.

Just before getting out of OnInit() -- one has to move the descendant
Controls INTO the container we want -- by a combination of
Remove() and AddAt().

So far so good. If we stopped here, we would have mostly all the parts of
visual enheritence.

The only problem is that any controls created dynamically in the descendant
control -- such as the TextBox control you created in the descendant's
OnLoad() -- would not exist at this point, and therefore could not be moved
into place...

So, in the Render() event we have to repeat the Remove/AddAt process
here...(for some reason, it doesn't work at all if you don't do the
Add/Remove
loop in the OnInit()...noth ing shows up on page).
At this point with the base classes code below, I have got the controls to
show up in the right place -- and correctly wired...but...w ell...I'm not
satisfied.

"What?! It works! Move on!" Yeah...well...t rue...but I don't understand
really why it works. Which means that I will lose a ton of time again on
another
project, repeating all my mistakes...etc.
So I have two questions.
a) In the OnInit() event, when I've created all the new controls dynamically
BUT NOT ADDED them to the page -- and you have only one DropDownList
in yours, does it report that Controls.Count = 2??? More disturbing, if you
look at their ID's..why are they BOTH THE SAME element?!?!

b) Why does this solution fail if I do not do the Loop/AddAt() -- to move
the children controls into the right location -- in BOTH OnInit and later
Render().
It appears to me that it should work fine if I just put it in the Render()
event. no?

c) And how could I improve the loop mechanism? In other words -- if class b
enherits from a -- is there any way that I can distinguish a.class[0] as
being from a rather than b? "wot?!" ...I think if you look at the loop you
will understand:

for (int i=(Controls.Cou nt-1);i>-1;i--)

{

tC = Controls[i];

if ((tC != ID_DivOuter) && (ID_DivLower.Co ntrols.Contains (tC)==false))

{

try

{

// Controls.Remove (tC);

ID_DivLower.Con trols.AddAt(0,t C);

}

catch {

s = "SHIT! " + tC.GetType().To String();

}
}

}
