passing values between pages (one is previouspage) with asp.net 1.x

i have a page opens a popup in that popup i get some property values for control in the previous page

i need to pass the values to the control vwhen i clik a button

what is the best choise

when i need session i can'nt refresh the previous page correctly so it fails for me (browser asks me a msgbox)

when i want to pass with query string my value is a html tag it allso fails because of security

thanks for helps

i realy need help talk to me guys

Can you clarify the question a bit.

You have a window you pop up that gathers some data that you want to write back to the previous page that the window popped up from?

If so you can use javascript to do it:

function SelectItem(item, invalue)
{
if (window.opener)
if (window.opener.closed == false)
if (window.opener.document && window.opener.document.forms[0] &&
window.opener.document.forms[0].elements[item])
{
window.opener.document.forms[0].elements[item].value = invalue;
}
window.close();
}

Passing values from a child window

hi all,
I have a parent window default.aspx which has a textbox(txtBox1) with
multiline property and a button.when the button is clicked a child
window pops up child.aspx.
I have four textboxes in child.aspx and a submit button.What I want to
happen is when I click the submit button all the values must be
displayed in the multiline textbox in a table format with header and
the values below or any formatted display with headers.
I am using,
window.opener.documents.forms[0].txtBox1.value method to pass the
values.
can anybody help me to fix the values from the child window to the
parent window in a formatted display.I have been trying this for a day.
thanksHello ssrivani@.gmail.com,
From what I understood, after opening the child window and filling in the ch
ild form, you want to be able to:
1- Format the form field values in an html table.
2- copy the resulting html to the opening window and have it inserted into t
he multi line text field.
Try the attached files and see if it works for you.

passing values from form to form

I was wondering if it is possible to pass values from one aspx page to another aspx page using properties?

I want to create a property on the 2nd aspx page lets say Name(), and pass in the values from the first aspx page. I know how to pass values like this to a user control, but is it possible to pass it to another aspx page?> I was wondering if it is possible to pass values from one aspx page to another aspx page using properties?

You can sort of do this, but not as directly as you're suggesting.

In your firstpage.aspx:

Public Sub Button_Click( sender As Object, e As EventArgs )
 Session( "Name" ) = "Value from textbox, or wherever"
 Response.Redirect( "secondpage.aspx" )
End Sub

Then, in your secondpage.aspx:

Private _name As String
Public Property Name As String
 Get
 Return _name
 End Get
 Set
 _name = Value
 End Set
End Property
Public Sub Page_Init( sender As Object, e As EventArgs )
 Name = Session( "Name" )
End Sub

If that doesn't help, perhaps you can explain more fully what you're trying to do.
That's what I'm trying to do. I knew that I can use session variables, just wondering if there's any other way to accomplish this.
You can store information into the QueryString as well.
Well, you can't directly access the second Page's properties from the first page, no.

After all, the second Page is not instantiated until the first is destroyed. So there can be no direct messaging between them.

It is for this reason that session variables exist. So, for "form to form" communication, session variables are ideal.

You can also create a single form thatacts like more than one form. If you're trying to keep information "alive" during a certain series of tasks, this might be a better way to go.

passing variables

When I try that it tells me that property is read - only!
any ideas.

passing variables between web page events & httpmodules events

Use the item property on the httpcontext object. It's a dictionary object
which stores key/pair values but it is available every the httpcontext
object is available.

Passing variables from ASPX page to ASCX control

I'm sure this has come up before but I could not find any post on it.

How can I read a variable or property that has been set on a ASPX page from
inside a ASCX control.

ASPX code:

public partial class MyClass: System.Web.UI.Page
{
protected string _companyID;
public string CompanyID
{
get
{
return _companyID;
}
set
{
_companyID = value;
}
}
....etc...

ASCX code:

public partial class Controls_MyControl: System.Web.UI.UserControl,
IPostBackDataHandler
{
protected void Page_Load(object sender, EventArgs e)
{
Page callingPage = (Page) this.Page;
//How to read the "CompanyID" property from the calling page??
}

Thanks,
FernandoChange this line of code:

Page callingPage = (Page) this.Page;

to:

MyClass callingPage = (MyClass) this.Page;

Thanks KJ.

But when I change to MyClass my code does not compile.
How to I add a reference to that class in my Control?

Thanks,
Fernando

I should have recognized that you are using .net 2.0 (this would
compile in 1.x).

In this case, I do not know of a means for referencing the parent page
because doing so (using the @.Reference directive, for example) would
create a circular reference.

I think a better design approach would be for the parent page to *tell*
the user control what its CustomerID is.

That is to say, create a method or property, such as SetCustomerId() or
CustomerID, on the control, rather than having the control attempt to
pull the value from the hosting page.

This may seem like double work, but, it is actually better design
because you can now put your control on *any* page without requiring
the hosting page to declare certain properties. The control is supposed
to be a self-contained entity (black box).

For example:

public partial class MyClass: System.Web.UI.Page
{
protected string _companyID;
public string CompanyID
{
get
{
return _companyID;
}
set
{
_companyID = value;
myControl.CompanyID = value; //keeps the control and page in sync
}
}

ASCX code:

public partial class Controls_MyControl: System.Web.UI.UserControl,
IPostBackDataHandler
{
protected string _companyID;
public string CompanyID
{
get
{
return _companyID;
}
set
{
_companyID = value;
}
}
}

define an interface in app_code that returns companyid. the have you pages
implement the interface (could inherit from a base page that implments the
interface. cast the page to the interface, and call method.

Thanks again KJ.

I used the suggested aproach (black-box) and it's all working great!
I set all the control properties from the aspx page. I also implemented all
the error-handling in case the control gets dropped into a page that does
not set up its properties.

THANKS!
