handling events between webpages..

P: n/a
Hi,
I am working on creating a webapplication and my design calls for creating
main webform which will have menu bar on left hand side and a IFrame which
will contain all the forms that are shown when menu items are clicked.Besides
these i would like to put a custom status bar. Any error message encountered
in any of the webpage will be displayed in the banner.
The problem iam encountering is how to access the customer status bar in
child forms that are displayed in the IFRAME. I cannot use
HttpApplicationState.Application object as i cannot put custom objects in
application object. Is that correct? Also, assuming that i can raise events
from the forms when error is encountered then the question is how do i
capture that event in my main frame. I don't want to register tons of events
in my main form for tons of objects that are there in my application. Since i
cannot attach word document in this post so i will try use following figure
to demonstrate what i am planning to accomplish:

Main Webpage(contains IFRAME, MENU BAR, STATUS BAR CONTROL)
________|_________
| |
Page1 Page 2(contains webcontrols)
|
Page1.1(contain webcontrols)

Assuming that main webpage shows page1 in the iframe which brings up
page1.1 when some command button is clicked and Page 1.1 contains web user
control. Now assuming user ecounters some error in the webcontrol. I want
that error message to be displayed in the status bar control of Main webpage.
I can raise error event from webcontrol which will be captured by Page 1.1 ,
the problem that remains is how to propogate that event to Main webpage.
Any suggestion on this approach or any better approach to handle this. I
know there is way to move control between webpages but i don't find that very
elegant solution for my problem.
Thanks

Instead of frames, use an HTMLTable to place different user or custom
controls that implement the various components of your page. If you are
worried about the performance of having to recreate all components upon
postback then take advantage of the Page fragment caching feature in ASP.NET
2.0. http://beta.asp.net/QUICKSTART/aspne.../fragment.aspx

Are there any particular reasons you want to use frames?

P: n/a

In the model that you presented, you referred to a "Main Webpage" in which
you wanted to insert a frame where another "webpage" should be able to
communicate events to the parent page. You can achieve this goal if you were
to think of the child page as a control that is positioned on the page (using
any of the formatting facilities that are available in HTML, not just an
HTMLTable)

You asked, "how do I display a web page in a particular cell of table?" The
answer is: in the same way as you would place a TextBox, a DropDownList or
any other server control on a webform. You can also using the cssStyle
attribute for advanced styling effects.

Thanks for Phillip's suggestions.

Hi SCS,

Regarding on your scenario, if you're using multiple frames (frame or
iframe) based page, the communcation between those frames does be a
problem. The ASP.NET serverside programming model is request/ response
based, so each time only one page/or handler 's request is under
processing, the runtime is not aware of another parent or child frame
because the frames/iframe are all clientside object model which supported
by client browsers. So generally we would have to use clientside scripts
for cross browser communation. For example, we can use following script to
access parent frame window or child frames:

window.parent
window.frames

Also, we can use window.parent.location to reset parent window's url
address and pass some querystring items to pass information to parent
window, this is also a certain means used commonly. (for example, the MSDN
web site
http://msdn.mcrosoft.com/library/)

In addition, since your web application want to have a consistent UI style
for all the pages in it ( have the menu and side navigate bar....), would
you consider use single page (instead of using iframe) and make UI
consistency through the ASP.NET 2.0 's Master Page feature? Master Page
can help us define a template page layout which is common for all the pages
in the site and we can create concrete pages based on the master page
template. And whenever we want to change any UI in the template part, just
modify the master page intead of modifying each concrete pages. Also,
using master page can avoid using iframe so that we can easlily access each
control on the page in serverside code.

Please feel free to let me know your consideration or concerns.

Thanks,

Steven Cheng

P: n/a
Thanks Philips and Steven for your responses. Using .NET 2.0 is not an option
for current project as thats a company decision and i cannot influence that
at this point of time.
Let me tell you my reason for using IFRAME rather than tables. As I
understand if i have to display a page in say 2nd cell in third row then i
have to alway write code like:

TableCell c = new TableCell();
c.Controls.Add("AspxPage.aspx");
and add this cell to my table.

Imagine doing this for every form that needs to be displayed:(. On the
contrary if i use IFRAME. All i have to do is tell the menu item(which
happens to be a hyperlink) that the target is IFRAME. After that i don't have
to worry about anything. Any child webpages that are opened from any of the
action in my application would be always shown inside the frame. I am not
sure if i can do that with table.
Please let me know if this still does not makes sense and i will try to
explain using some example.
Once again i thank you for responding to my queries. On side note, If i
have to draw something using paint and then post it in this form then is that
possible? I don't see any option to upload attachments.

based, so each time only one page/or handler 's request is under
processing, the runtime is not aware of another parent or child frame
because the frames/iframe are all clientside object model which supported
by client browsers. So generally we would have to use clientside scripts
for cross browser communation. For example, we can use following script to
access parent frame window or child frames:

window.parent
window.frames

Also, we can use window.parent.location to reset parent window's url
address and pass some querystring items to pass information to parent
window, this is also a certain means used commonly. (for example, the MSDN
web site
http://msdn.mcrosoft.com/library/)

In addition, since your web application want to have a consistent UI style
for all the pages in it ( have the menu and side navigate bar....), would
you consider use single page (instead of using iframe) and make UI
consistency through the ASP.NET 2.0 's Master Page feature? Master Page
can help us define a template page layout which is common for all the pages
in the site and we can create concrete pages based on the master page
template. And whenever we want to change any UI in the template part, just
modify the master page intead of modifying each concrete pages. Also,
using master page can avoid using iframe so that we can easlily access each
control on the page in serverside code.

Please feel free to let me know your consideration or concerns.

Hello SCS,
You are correct in saying that "if i use IFRAME. All i have to do is tell
the menu item (which happens to be a hyperlink) that the target is IFRAME."
But then you lose a requirement that you put forth at the outset of this
thread; namely to be able to handle events from the child page in the parent
page. I had to do the same in a previous project (the website of the City of
North Vancouver, a municipality in the province of British Columbia, Canada
). So maybe I should use it here as a case study.

If you look at the City of North Vancouver ‘s website at http://www.cnv.org,
you will see that it has thousands of pages (that used to be separate asp
pages before I redesigned it). Now it is only one web form in asp.net

The page is divided in separate areas managed by custom server controls; one
for the top menu (that is dynamically generated out of an oracle database
updated momentarily as a new page is added to the site), a footer, a side
menu (that appears a tree with collapsible/expandable items) and a content
area (which is similar to the child page that you intended to place in a
frame).

By using one page, I manage to process events from the content area within
the parent page. The content area does not only display static HTML content
but also applications as in this link
http://www.cnv.org//APPS/PROPERTY_SEARCH/

In summary if you want to process events, server-side, from the content page
to the main page then you have no option but to think of the content page as
a control. Technically any function that you can carry in an aspx page class
you can convert to an ascx without any loss of functionality. As for the
display considerations, you can use cascading style sheets to achieve the
final look and feel of your site in ASP.NET 1.x

Thanks Philips and Steven for your responses. Using .NET 2.0 is not an option
for current project as thats a company decision and i cannot influence that
at this point of time.
Let me tell you my reason for using IFRAME rather than tables. As I
understand if i have to display a page in say 2nd cell in third row then i
have to alway write code like:

TableCell c = new TableCell();
c.Controls.Add("AspxPage.aspx");
and add this cell to my table.

Imagine doing this for every form that needs to be displayed:(. On the
contrary if i use IFRAME. All i have to do is tell the menu item(which
happens to be a hyperlink) that the target is IFRAME. After that i don't have
to worry about anything. Any child webpages that are opened from any of the
action in my application would be always shown inside the frame. I am not
sure if i can do that with table.
Please let me know if this still does not makes sense and i will try to
explain using some example.
Once again i thank you for responding to my queries. On side note, If i
have to draw something using paint and then post it in this form then is that
possible? I don't see any option to upload attachments.

Thanks for SCS's respone and Phillip's continue followup,

So I support Phillip's idea ,however, considering SCS's actual scenario the
structure may not be changed. Have you already built the main page and
those sub pages which will be displayed in iframe? Also, if using Philip's
suggest that use Table to constructure the layout of your main page, you
can no longer use sub pages, we have to use WebControls or
Usercontrols(ascx) to construct the UI. Also, if you've decided to use
Iframe structure, as I've mentioned before, we'll have to utilize
clientside script to do cross frame communication....

So what's your project's current status?

P: n/a
Thanks a lot for replies. My project is in middle of development and main
page is also done. We cannot afford to use user controls as we have lots of
webpages and converting them into user controls if not difficult then it is
not something which would be acceptable to people in our development team. We
have pretty big development team. Also, if I convert webpages to user
controls then i still have to have to put those controls on my webpage and
hide and show those controls as need arises. correct?

Thanks

Thanks for SCS's respone and Phillip's continue followup,

So I support Phillip's idea ,however, considering SCS's actual scenario the
structure may not be changed. Have you already built the main page and
those sub pages which will be displayed in iframe? Also, if using Philip's
suggest that use Table to constructure the layout of your main page, you
can no longer use sub pages, we have to use WebControls or
Usercontrols(ascx) to construct the UI. Also, if you've decided to use
Iframe structure, as I've mentioned before, we'll have to utilize
clientside script to do cross frame communication....

So what's your project's current status?

| Hello SCS,
|
|
| You are correct in saying that "if i use IFRAME. All i have to do is tell
| the menu item (which happens to be a hyperlink) that the target is
IFRAME."
| But then you lose a requirement that you put forth at the outset of this
| thread; namely to be able to handle events from the child page in the
parent
| page. I had to do the same in a previous project (the website of the City
of
| North Vancouver, a municipality in the province of British Columbia,
Canada
| ). So maybe I should use it here as a case study.
|
| If you look at the City of North Vancouver ‘s website at
http://www.cnv.org,
| you will see that it has thousands of pages (that used to be separate asp
| pages before I redesigned it). Now it is only one web form in asp.net
|
| The page is divided in separate areas managed by custom server controls;
one
| for the top menu (that is dynamically generated out of an oracle database
| updated momentarily as a new page is added to the site), a footer, a side
| menu (that appears a tree with collapsible/expandable items) and a
content
| area (which is similar to the child page that you intended to place in a
| frame).
|
| By using one page, I manage to process events from the content area
within
| the parent page. The content area does not only display static HTML
content
| but also applications as in this link
| http://www.cnv.org//APPS/PROPERTY_SEARCH/
|
| In summary if you want to process events, server-side, from the content
page
| to the main page then you have no option but to think of the content page
as
| a control. Technically any function that you can carry in an aspx page
class
| you can convert to an ascx without any loss of functionality. As for the
| display considerations, you can use cascading style sheets to achieve the
| final look and feel of your site in ASP.NET 1.x

Hi SCS,

Yes, you need to load different usercontrol into the main page's table
section when navigating between different concrete pages. Also, you can
choose to create the main page UI as UserControl so as to include them in
each of your concrete pages, just something like Master page in 2.0...

Thanks,

P: n/a

One more approach is to implement the main page as a base class to be
inherited by each of the webforms that the other developers create (or
already have), e.g.

Public Class WebForm1
Inherits MyAppBasePageClass ‘ instead of Inherits System.Web.UI.Page

Thanks a lot for replies. My project is in middle of development and main
page is also done. We cannot afford to use user controls as we have lots of
webpages and converting them into user controls if not difficult then it is
not something which would be acceptable to people in our development team. We
have pretty big development team. Also, if I convert webpages to user
controls then i still have to have to put those controls on my webpage and
hide and show those controls as need arises. correct?

Thanks

Thanks for SCS's respone and Phillip's continue followup,

So I support Phillip's idea ,however, considering SCS's actual scenario the
structure may not be changed. Have you already built the main page and
those sub pages which will be displayed in iframe? Also, if using Philip's
suggest that use Table to constructure the layout of your main page, you
can no longer use sub pages, we have to use WebControls or
Usercontrols(ascx) to construct the UI. Also, if you've decided to use
Iframe structure, as I've mentioned before, we'll have to utilize
clientside script to do cross frame communication....

So what's your project's current status?

| Hello SCS,
|
|
| You are correct in saying that "if i use IFRAME. All i have to do is tell
| the menu item (which happens to be a hyperlink) that the target is
IFRAME."
| But then you lose a requirement that you put forth at the outset of this
| thread; namely to be able to handle events from the child page in the
parent
| page. I had to do the same in a previous project (the website of the City
of
| North Vancouver, a municipality in the province of British Columbia,
Canada
| ). So maybe I should use it here as a case study.
|
| If you look at the City of North Vancouver ‘s website at
http://www.cnv.org,
| you will see that it has thousands of pages (that used to be separate asp
| pages before I redesigned it). Now it is only one web form in asp.net
|
| The page is divided in separate areas managed by custom server controls;
one
| for the top menu (that is dynamically generated out of an oracle database
| updated momentarily as a new page is added to the site), a footer, a side
| menu (that appears a tree with collapsible/expandable items) and a
content
| area (which is similar to the child page that you intended to place in a
| frame).
|
| By using one page, I manage to process events from the content area
within
| the parent page. The content area does not only display static HTML
content
| but also applications as in this link
| http://www.cnv.org//APPS/PROPERTY_SEARCH/
|
| In summary if you want to process events, server-side, from the content
page
| to the main page then you have no option but to think of the content page
as
| a control. Technically any function that you can carry in an aspx page
class
| you can convert to an ascx without any loss of functionality. As for the
| display considerations, you can use cascading style sheets to achieve the
| final look and feel of your site in ASP.NET 1.x
