Web Forms :: Data Interaction Between Master Page And Content Page?
Mar 12, 2010
I have got two pages - a master pages (Master1) and an .aspx page (default), with the content page attached to the master page.
However, I have run into a problem
I have some data controls like drop down boxes and textboxes in the master page, with a gridview of data in the content page. What I want to achieve is a situation where when a user searches for an item using the texbox in the master page, the gridview in the content page displays the results of that search parameter made.

I have 2 nested master pages, lets call them MP1 and MP2. MP1 is top level, MP2 is level
2. Then I have several content pages. Lets say I have 2 content pages for now CP1 and CP2. Each content page has a form that will have some user input and a SaveData()function that saves the data to a database. Each content page also has a "Save" button that calls the SaveData() function.
MP1 and MP2 have several link buttons. The functionality I need is this: Any time a user clicks on a link button in MP1 or MP2, the SaveData() function of the currently loaded page should be called. This is to save the data even if the user forgets to click the "Save" button before leaving the page.
So far I can do this from the link buttons in MP2. I followed the master pages tutorial # 7
In the .cs file for MP2, I declare:
public event EventHandler SaveData;
then i raise a "SaveData" event any time a link button in MP2 is clicked.in every content page (CP1, CP2 etc.) aspx file, I have Master Type directive to assign the Master Page to MP2.
in CP1, CP2 etc .cs file, i have the following code:
protected void Page_PreInit(object sender, EventArgs e)
{
//wire up the SaveData event from MP2 to Master_SaveData function in this page.
Master.SaveData += new EventHandler(Master_SaveData);
}
private void Master_SaveData(object sender, EventArgs e)
{
//when the MP2 SaveData event is raised, save the data in this page.
SaveData();
}
All of this works fine.Problem is I am not able to do a similar thing from MP1.What I have tried so far is to raise an event in MP1 that is handled in MP2. When the event is handled in MP2, it raises the SaveData event to be handled in the page. The event in MP1 is null and hence never raised.

Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008
CSS sample:
body
{
height:1200px;
width:920px;
border-style:solid;
border-color:blue;
padding:10px 10px 10px 10px;
}
#toptext1
{
position:relative;
top:-225px;
right:-500px;
font-size:22px;
font-weight:bold;
}
From the master page:
<body>
<form id="form1" runat="server">
<asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server"
AlternateText="CookNook" Width="449px"></asp:image>
<p>
<asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label>
</p>
From the content page:
<%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" />
</asp:Content>
When I was doing this without a master page it worked so where am I going wrong with the attributes?

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):
System.Web.HttpException: Content controls are allowed only in content page that references a master page.
This is followed by Stack Trace:
[HttpException (0x80004005): Content controls are allowed only in content page that references a master page.]

I am not using any Content Place Holder or Master Page (does the error refer to the Site.Master file because while I can see it in. Solution Explorer, I never use it. All of my aspx files look like this along the top with no reference to Site.Master:

I have a master page with a textbox that I want to use for a search, and display the results on the content page.
I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.
The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.
How do I set this master page search box as the parameter for my datasource?

I have a master page with a form on it. It's a people search form. When the user clicks on the search button it goes to the search results page that uses the same master page. With the code below I get the info off the master of the current page. Howdo I grab that info from the first page?
Here's the code:
Master page:
< FORM id=formEmpSearch method=post action=~/About/peopleSearch.aspx runat="server">
< asp:TextBox style="WIDTH: 153px; HEIGHT: 12px" id=txtSearchName onfocus="this.value=''" runat="server" CssClass="searchBox">
Master Code Behind page:
Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls
Partial Class mstrIntranet
Inherits System.Web.UI.MasterPage
Public Property mSearchName()
Get
Return txtSearchName.tex
End Get
Set(ByVal value)
txtSearchName.text = value
End Set
End Property
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
txtSearchName.Text = "People Search"
End Sub End Class
Search Results Code Behind page:
Partial Class PeopleSearch2

Public SearchName As String
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Wondering if it is possible to access a master page's hidden field (ex. <Input Type="Hidden" ID="TestHiddenField" Value="testValue"/>) From a Content Page's C# Pack CS Page.If it is possible, How do I go about doing so? I have tried:
PreviousPage.Master.FindControl("[TestHiddenField]") but no .Value attribute and no luck in general.

I have a MasterPage where I use the menu control. Clicking a menu item loads a new content page. That part works fine.
I would like to use staticselected style to change the look of the selected menu item. However, when the new content page loads, the staticselectedsyle formatting does not work.

Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
