Popup Window generated from Server Side

HarveyB

I would like to generate non-modal popup windows from
ASP.Net code-behind. I have tried using Client Side
scripting like "function Test(){
window.open('test.htm',_blank,
'height=200,width=400,status=no,toolbar=no,
menubar=no,location=no resizable=no
scrollable=no');
but I can't seem to invoke the client side script from
within a Server Side Form. I know I can use the context
with to Response.redirect or Server.transfer to return a
different page, but can't figure how generate a pop-up
window for an 'About' page or a "Contacts" page.

I don't think that solves the problem. It will place a

Hi HarveyB,

I do not believe that there is a method to open a client window without
using the client script.
For security concern, it is non-security to open a window from server-side.
Did I answer your question?

You cannot invoke windows from the server without using some form of
remoting listener loaded at the client. HTTP is get/response protocol and
doesn't work like that.

The best you can do is pass out the information to invoke the window client
side with client side script, either from a buttonclick/hyperlink or via a
script event such as onload for body. There is some code for one of these
below.

The sample worked, but unfortunately I think I will need
to re-architect to do what I want. I have 3 problems.

1. The buttons are implemented inside an ASP:Datalist Cntl.
2. The plan was to encapsulate my menus in a user cntl
(ascx).
3. I am using code-behind.

Should I just go back to the drawing board. Each of the
conditions above seems to make implementing the sample
extremely difficult, if not impossible.

That is somewhat of a disappointment give that all 3 are
touted as advantages of ASP.NET.

Hi HarveyB,

It seems that you want to handle the button click event in the Datalist
control.
Here is a link about it. You may have check.

Ok, then is there a way to pass a message (of some type)
to the client side so that a client side javascript can be
fired to open the window.

I mean 'message' in the most generic meaning of the term.
I just want some way to detect the button click inside the
Datalist, handle the event on the server-side and then
hand it off to the client side. The reason for this is so
that the menu inside the datalist control can be dynamic
and based on either an XML file or a SQL Query.

It seems that this should be easy, but I have tried quite
a few ideas without success.

Hi Harveyb,

Since the Browser/Server modal is based on request. That is to say, the
server will response to client browser with the html code at last when the
client make a request.
The server can not actively generate the html file (i.e. javascript )
without the browser request.
Have you check the suggestion of Steven, it is one method to invoke the
javascript in code behind?
Have you also check my last post that can handle the click event in the
datalist in my last post?

Did I answer your question?
If you have any related question,please feel free to let me know.

HarveyB

The replies by both you and Steven are good as far as they
go. They explain that it is possible on the server side
to create and then register a client script.

That means that a user could click a button that would
postback a request for information. If you wish to return
the info in a pop-up, non-modal window, you could generate
a script to initiate the popup.

Of course you are still left with the problem of how that
script gets invoked. Having the user press ANOTHER button
is clearly not acceptable. Using an event such
as 'onload' is only useful if there is some way for the
script to determine what/when it is to take action.
The 'onload' event would fire everytime the page was
invoked, but the window.open would be discretionary.
There needs to be some mechanism to pass a message between
server and client in order for the script to know what to
do.

The obvious possibility would be in a hidden input
control. But the client side script seems to have trouble
reading the hidden control, especially if the control is
encapsulated in a User Control. It seems the User Control
compile process pre-pends the id of the User Control to
the control id, but the script can't use that name. So
there doesn't seem to be any way for the script to read
the value of the hidden control.

This make the proposed solution either extremely difficult
or perhaps impossible. Perhaps the correct approach is to
write a Server Control. That seems like an unnecessarily
complex approach, but may be the correct way to approach
this. Perhaps User Controls are best thought of as Server-
side includes.

I don't think that solves the problem. It will place ascript on the returned page, but how is the script

invoked

from the Server Side. The issue here is to open a pop-

up

window from the server side. 'Window' is a client- sideobject.

Hi Harveyb,

For the design of Browser/Server modal, I think you may use a javascript
function to restrieve the message from server repeatedly.
e.g.
You have two pages.
page1: the main page you show the datalist to the client.
page2: the page used to response the message to client just as you "push"
the message to the client.
a javascript function run repeatedly to retrieve the data from page2.
function querystatus()
{
GetXMLHTTP();//a customer function to retrieve the msg the server want
to response to the client.
setTimeout(querystatus,300);
}

For detailed information, please refer to the link below.

The replies by both you and Steven are good as far as they
go. They explain that it is possible on the server side
to create and then register a client script.

That means that a user could click a button that would
postback a request for information. If you wish to return
the info in a pop-up, non-modal window, you could generate
a script to initiate the popup.

Of course you are still left with the problem of how that
script gets invoked. Having the user press ANOTHER button
is clearly not acceptable. Using an event such
as 'onload' is only useful if there is some way for the
script to determine what/when it is to take action.
The 'onload' event would fire everytime the page was
invoked, but the window.open would be discretionary.
There needs to be some mechanism to pass a message between
server and client in order for the script to know what to
do.

The obvious possibility would be in a hidden input
control. But the client side script seems to have trouble
reading the hidden control, especially if the control is
encapsulated in a User Control. It seems the User Control
compile process pre-pends the id of the User Control to
the control id, but the script can't use that name. So
there doesn't seem to be any way for the script to read
the value of the hidden control.

This make the proposed solution either extremely difficult
or perhaps impossible. Perhaps the correct approach is to
write a Server Control. That seems like an unnecessarily
complex approach, but may be the correct way to approach
this. Perhaps User Controls are best thought of as Server-
side includes.

Hi Harveyb,

Since the Browser/Server modal is based on request. That

is to say, the

server will response to client browser with the html code

at last when the

client make a request.
The server can not actively generate the html file (i.e.

javascript )

without the browser request.
Have you check the suggestion of Steven, it is one method

to invoke the

javascript in code behind?
Have you also check my last post that can handle the

click event in the

datalist in my last post?

Did I answer your question?
If you have any related question,please feel free to let

me know.

Ok, then is there a way to pass a message (of some type)
to the client side so that a client side javascript canbefired to open the window.

I mean 'message' in the most generic meaning of theterm.I just want some way to detect the button click insidetheDatalist, handle the event on the server-side and then
hand it off to the client side. The reason for this issothat the menu inside the datalist control can be dynamic
and based on either an XML file or a SQL Query.

It seems that this should be easy, but I have triedquitea few ideas without success.

Hi HarveyB,

I do not believe that there is a method to open aclientwindow without
using the client script.
For security concern, it is non-security to open awindowfrom server-side.

I have developed a popup control to accomplish what you want. It will
open a child window and responds to postback events. It can be placed
on an ASP.NET page like this:

<PowerUI:Popup id="pPopup" runat="Server" PopupWidth="300px"
PopupHeight="300px" OnPopupPostBack="pPopup_PostBack"
UrlToPop="UserEdit.aspx">Edit</PowerUI:Popup>

Clicking on "Edit" will open the the page UserEdit.aspx in a window.
The child window can also be opened by issuing:

pPopup.PopupWindow();

in the code-behind....

Notice that you can subscribe a method to the event "OnPopupPostBack".
This is fired from executing the static method on the child window
code-behind like this:

Popup.CloseWindow(Page,true,"PostBack Message",true);

The parameters are as follows:
1. Current "Page" object
2. Fire postback event on Parent Page
3. Optional argument in case you want to pass something back to the
parent page
4. Close the child window after postback.
This can be used in a data list or datagrid for popping up edit/detail
windows. To use the Popup control in a datagrid might look like this:

<asp:DataGrid id="dgGrid" runat="server">
<columns>
<asp:TemplateColumn>
<ItemTemplate>
<PowerUI:Popup id="pEdit" runat="server"
OnPopupPostBack="pEdit_PostBack" UrlToPop='<%# "UserEdit.aspx?UserID="
+ ((User)Container.DataItem).UserID %>'>Edit</PowerUI:Popup>
</ItemTemplate>
</asp:TemplateColumn>
</columns>
</asp:DataGrid>
If your interested in the control I can email to you as an Alpha
version. I will be selling the control soon so I will not be
providing source code...

I will examine your sample code as to it appicability to
communicating between Server and Client.

As to the original topic, we were on the right track. It
only required a slight twist. If one creates and
registers JavaScript code on the Server Side, but does NOT
wrap it in a function, the registered code will execute as
inline script after Page_Load. This does allow a popup
window to be invoked from the Server-Side. I have tested
this in IE and Netscape.

Thx, I consider the original issue closed. I may wish to
pursue the issue of messaging between server & client in a
new thread.
