Web Forms :: Passing Value From Child Page To Parent Page?

Jan 11, 2011

In the parent page i'm displaying all the user details and one of the detail is the list of accessible clients in a list box. the clients can be removed or added using the add or remove images next to the list box.

Clicking on the Add image will show you the list of available clients in a new page(child) and also showing currently available clients to the user with checked status.

Let me explain how the available clients for the user is displayed in the child page. In the parent page load on the 'Add' image 'OnClientClick' i'm passing the ClientId of a hidden field in which all the selected clients for a user is stored.

The problem i'm facing here is when i altered the selected clients in the child page and clicking on the OK button will change the value of the listbox in parent page using the clientID of the listbox which i'm passing, but if i once again click the 'Add' button it shows the original values which is stored at the time of parent page load. The problem is i'm not doing any postback here so that the original values registered during 'OnClientClick'of 'Add' button is not altered.

I need to access a variable that is declared in a master page to a child page. I'm using asp.net 2.0 (vb). I'm sure this should be easy and is down to my inexperience with asp.net! A rough guide to my code is below;

MASTER PAGE

<script runat="server">

Forms Data Controls :: Pass Value From Child (popup Window) To Textbox Within Listview In Parent Page

May 25, 2010

I have a listview that has n rows.

Within the EditItemTemplate and InsertItemTemplate I have a cell that has a textbox and a button.

When the button is clicked a popup window is shown, where the user can upload a picture. The name of the uploaded picture is retrieved.

Now I want to send that picture name back to the textbox within the listviews EditItemTemplate or/and InsertItemTemplate (that is ofcourse one at a time depending on what the user is doing, inserting or editing a row).

The code I have written so far looks like this. The below code has been abbreviated

[Code]....

The code behind looks like this (also abbreviated). Actually I don't think the code behind is needed, since its mainly javascript from the popup window (child page), but nevertheless here it goes.

[Code]....

And at last the child page / popup page.

Well there is not anything to see here, cause I'm using the Telerik RAD upload control, which is doing everything for me.

However the line below may be of interest. Here I'm taking the name of the uploaded file (picture) and printing it to a label.

UserControl - Accessing A Child Control In The Parent Page?

Nov 3, 2010

If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).

I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").

If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".

But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).

Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.

The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.

C# - Call Child Iframe Method From Parent Aspx Page?

Jul 26, 2010

I've created one aspx page Default.aspx. It contains iframe with child.aspx. File Child.cs contains web methods which should be called by parent page.

As I understand I need to receive the instance of Child class so then I'll be able to them call. How can I make this?

Default.aspx (Parent page)

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Parent_Child_Iframe._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>.....

So How I can call getResultData () from Child.aspx.cs by clicking Button on the parent page.

The main difficulty is that I can't use Javascript to collect the information from TextBoxes because the task is more complicated and I can use only server methods.

Web Forms :: Passing Values From Parent Page To User Control And Maintaining The Values Added

Mar 18, 2011

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.

So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.

So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"

Is there a way to resolve this issue? may be Dictionary List?

VS 2010 - Master / Child Page Layout - Embed Third Party Website As Child Page

Aug 29, 2011

I have a web application that uses the master/child page layout you get by default (at least in a VS2010 web project). The Masterpage has a NavigationMenu, each item on that NavigationMenu has a NavigateUrl that looks like "~/Pages/MyPage.aspx". This automatically opens 'MyPage' in the Content of the Masterpage, so that the master page with menu and header etc stays visible.

Now, the client has a guestbook on her old website (I'm basically rebuilding her website, adding the ability for her to upload new content in her browser), and she wants to keep it. This guestbook is from a 'free guestbook' third party website, over which I have no control. It's simply a website in the form [URL] .... which shows the guestbook for a user 'Username'.

In her old website, I was using frames, so the menu on the left side was in a different frame, and I would simply open the third party website in the center frame. That would create the illusion that the guestbook was on her site, while it was actually a completely different website in a separate frame.

In my new website I'm no longer using frames, but the master/child layout as explained. Is it still possible to 'host' or 'embed' this third party website as a 'child' of the master page?

I tried just putting the url to the guestbook in the NavigateUrl of a NavigationMenu item, but that doesn't work, it just navigates to the third party website and doesn't embed it in any way.

Javascript - Passing Data Between A Parent Window And A Child Popup Window With JQuery

Dec 3, 2010

I have the following HTML

<tr>
<td class="label" valign="top">
Affiliate Party
</td>
<td class="field">
<input type="hidden" name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyId" id="AffiliatePartyId" />
<input name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyName" type="text" id="AffiliatePartyName" class="PartyLookup" />
</td>
</tr>

and the following Javascript/jQuery

$(".PartyLookup").after("<img src='Images/book_open.png' class='PartyLookupToggle' style='padding-left:4px;' />");
$(".PartyLookupToggle").click(function () {
window.open("PartySearch.aspx", "PartySearch", "width=400,height=50");
return false;
});

I need to be able to flag ANY PartyId input field with class="PartyLookup" so that it will modify the DOM and include the image next to the input field. The popup window returns data to populate both the hidden and text fields, but since the click() is generic I need to pass it the ID of the input field.
