Web Forms :: Content Page Validation Doesn't Work Under Master Page?
Dec 17, 2010
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).
I have a search control in my master page with the following validation on the search btn's OnClientClick:
[Code]....
Then in the content page I have various controls with validation and a validation summary. I have few custom validators on the content page like below:
[Code]....
which uses the clientvalidationsfunctions which set the validity of the page.Now when I leave the search box in the header blank and I click the submit btn in the content page it posts me back to same (source) page and while debugging I find that the Page.IsValid is false. But if I write something in the search textbox in the master page and the fill the required fields in the content page and click the submit btn in content page it works fine. Why is that so? My validation groups are different on master page and content page.
The master page lies in Root/MasterPages/masterpage.master
Now this image is displayed in a content page which is in Root/SomeDir/ContentPage.aspx, but it doesn't work in a content page which is in Root/SomeDir1/SomeDir2/ContentPage.aspx. Why?
in my project all css files are in Resources/css folder and all images are in Resources/images folder. while runing the project it get background color from css file but don't display background or any image. stablish the correct path to display image.
My project has the following repeater menu shown on the Master Page. I need this menu to remain hidden until the user logs in. How do I access from content page?
I am using Master page and Content page combination.But how can i access <body> tag and it's event (onload, onunload) of Master page in .aspx page that is not a content page.
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?
I am having asp:hyperlinks in my master page, which i use as my page headers. I would just like to change the text format of the hyperlink when a content page is loaded.
the CS code for accessing the master page contents from content page?
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:
Following is the structure of the pages in application
[Code]....
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 .....
I want to call a javascript method during page load. I am using application.master of the sharepoint server 2007 as the master page . In the content page i want to call a custom method named OnLoadFun() during loading the content page. I have written the function inside script tag in the PlaceHolderAdditionalPageHead id section of the content page.
[Code]....
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 javascript function on my Master page, how do I access it with a dropdownlist of a content page. Not from codebehind, I can do that, but from the control itself such as the onSelectedIndexChanged event.

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
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?
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..
