Web Forms :: Master Page Hidden Field Accessed Through Content Page?
Aug 18, 2010
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.
From the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page. Is the hidden field the proper approach to this and if so how do I read the value set in the hidden field in the subsequent get request. If the hidden field is not the proper approach for this then what else should I use?
I have a master page homeMaster.aspx and many content pages. However the situation is I have few .html pages. Now when a user clicks on a link the html page should get loaded.inside the master page. The problem is these are .html and not content page with .aspx.
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?
In my ASP.NET main page I have one hidden field and and one button. When the user clicks the button I am showing the pop up (child page). I need to access a Hidden field while the pop up is loading. How could I access the Hidden field using c#?
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.] System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +9744256 System.Web.UI.Page.get_Master() +55 System.Web.UI.Page.ApplyMasterPage() +14 System.Web.UI.Page.PerformPreInit() +51 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1104
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:
So I have my login and password txtboxes in the master page header, When I click on login button it should hide those boxes and display something else.But everytime I navigate to another content page they get visible again. What it the best solution to keep them hidden while the user is logged in?
Following is the structure of the pages in application
Suppose the user is on ..../paycheck.aspx which is the content page. But when ...../paycheck.aspx loads, "lnkDynamic" properties "Text and PostBackUrl" must be set. Which events should be handled .....
How do i call the OnLoadFun method so the i is being called onload time. i tried putting window.onload=OnLoadFun surrounded by script tag within the PlaceHolderMain content section.

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:
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 Inherits System.Web.UI.Page Public SearchName As String
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim mpTextbox As TextBox mpTextbox = CType(Master.FindControl("txtSearchName"), TextBox) SearchName = mpTextbox.Text
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?
The problem with my web application is when ever i load the home page - The master page as well as content page loads ---This seems fine but when i navigate thorugh the website which have the same Master page but diffrent content page .... the master page loads again. What i want to do is ..I want to keep the master page intact and only the content page loads. How can I accomplish it..
I have very simple validation on the aspx page (highlighting not valid textbox), and it works perfectly. But when I try to work with this page using MasterPage, I've got an error - "Object reference not set to an instance of an object." (with reference to the line "aControl.BackColor=Drawing.Color.White" - underlined).
