Web Forms :: Accessing Properties Of A Masterpage?
Jun 12, 2010
In my application, I use nested master pages. In the main.master which is the top level, all encompossing master page, I have some properties. I want to set the value of this property from a user control embedded into the page which is using master page which is embedded into main.master. To clarify further, here's the hierarchy
I'm embarrassed to ask this here because it's clearly been duplicated several times already on StackOverflow. I've read a lot of stuff including:
[URL]
I think I've done exactly what those article say, but it's not working for me.
Here's the top of my master page, named "MasterNoNews.master":
[code]....
In the first case, VS is telling me System.Web.Ui.MasterPage does not contain a definition for urrentUser. In the second case, VS says the type or namespace 'MasterNoNews' could not be found.
I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain content if a session variable is not null.
I'm working on a project that uses a master page. When the page loads I'm calling a class (which I feed and ID into) to get back certain values for a location that the user has selected. Things like town name etc.
On the home page I have a user control which has some statistics for that location too.
Is there a way that I can get the user control to pull values from the class invoked by the Master Page (which has already been fed the ID, hit the db and pulled back the values), rather than creating a new instance of the class within the user control and having to supply the ID and hit the db all over again? This is now I'm calling the class in the masterpage. I have a method "CheckForStoredLocation" that goes off and gets all the data I need.
So I have a sitemaster page and I am getting header and footer controls from it. But for a perticular page I would like not to show the footer and just the header.
Therefore, I am trying to access the master page table control with id "footer".
What I have tried and they all didnt work. First I tried,
Dim ptrMaster As MasterPage = Page.Master ptrMaster.FindControl("footer").Visible = False
This gives me a null pointer error.
Then I tried to put in a accessor method on the site.master (masterpage) itself.
Public Sub HideFooter() Me.Controls("footer").Visible = False End Sub
But the problem here is when I create a masterpage object on the page that I would like to not show the footer. I cant see the method. So if I do
Dim ptrMaster As MasterPage = Page.Master ptrMaster.HideFooter() HideFooter doesnt show up as a method.
I am currently working on an application implementing custom localization features. I have created a number of web user controls for different activities on user designed pages. I wish make my webcontrols to check if the page using the control is a simple page or content page of a master page. In case of simple page we need to change page direction from ltl to rtl. In case of content page we need to change direction of master page.
I have a MasterPage in my project which it contains a FormView and the FormView is databound with a Connection String to a SQL DataBase.
This FormView is selecting users information from Database, when the ContentPage is loading, Im trying to get the information from the FormView of MasterPage and load them in Content Page, but it is not working fine for me.
For Example:
In MasterPage I have a FormView such as follow:
Name: Amir
LastName:Zandi
Username:amirzandi
In ContentPage, I have a Label and I want to get the name from MasterPage and replace it with the text of the Label.
I am doing this at PageLoad of Content Page with the Following Code:
[code]...
At the page load of ContentPage, it says that it could not find the FormView1
but after I refresh the page, it works fine.
is there anyway for me to ask the FormView in MasterPage to DataBind and After that, it retrieves the Data from FormView and place them into the ContentPage.
I also tried: fv.databind() but it is not working.
I have a main MasterPage that, as intended, forms the entire layout of my site. It has a bunch of methods common to all pages that use the mastertype, such as EnsureLoggedIn and such.
I want to move on to using nested masterpages to open up better layout options in some of the pages, but I am running into an issue. I get the layout of the nested masterpages fine, but I cannot access any methods in the parent masterpage.
I know my explanation seems a little sparse; I'm not exactly sure how to word what I'm looking for, heh. But here's a short example:
i have a <div> named 'mydiv' on a web page and have set it's runat property as <server> so it is visible within
my vb.net server side code.
i can see the mydiv within the server side code.
my question:
how do i adjust the height/style of the <div> withion the vb.net code so that whe the page is posted back the new height/style settings apply. how do i get to the style properties server side?
I am currently working on a page that displays a set of questions as retrieved from an XML source. I can print the questions out fine by using a ListView and the ItemDataBound event. On PostBack it seems I can get some property values (Text), but not others (ID). I need to get the ID so I can match up the answer to the appropriate question.
Here is the ListView:

I just don't understand the Life Cycle stuff that well for advanced issues like this. I'd prefer not to use the Request.Form collection for this, but I will if it's the last resort.
I have a regular method I want to call. I need to use properties of the GridViewRowEventArgs Class within this method.
i.e.
[Code]....
Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.
masterpage with a contentPlacholder multiple pages which use this masterpage and implement a base-class (fooPage) fooPage has a certain property (fooProperty)
[Code]....
Obviously this is not going to work - but how can I achieve this?
I know the alternative: call a method from the masterPage in the contentPage with fooProperty as a parameter - but i would like to rather have a pull-system in this case...
i want when user login by client show some information for all page that user panel have and all page are base masterpage and i cant find this propertise
I'm accessing a Masterpage property from a regular page by doing the following:
[Code]....
I get the following error message:
Compiler Error Message: CS0246: The type or namespace name 'SecondMasterPage' could not be found (are you missing a using directive or an assembly reference?)
My base class file is a file called BaseClass.cs in my App_Code directory. Other functions in there work without errors. Why?
Why i can't access MasterPage's public property (MessagePlaceholder) from other Class (Errors) ?Error compiler gives me is "Error 1 The type or namespace name 'MyMasterPage' could not be found (are you missing a using directive or an assembly reference?)"my master page code behind
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls;
public partial class MyMasterPage : System.Web.UI.MasterPage { public string MessagePlaceholder
I want to be able to extend the System.Web.UI.Page class and then easily access those properties from the Markup. I know I can do it from the codebehind, but is it possible from the Markup?
I'm changing the CSS of my menu items during runtime to reflect which page is currently being viewed. It works fine. But, I have a nested master page that needs to change the CSS of the master page's items. How I can access the master page's menu items?
We have added some custom profile properties to the web.config - what we want to do is have the code access them once (when user logs in) and cache this so that the code doesn't have to hit the database each time we call Profile.<our custom profile property name>
What we see is a call to GetProperties or GetProfile each time we access Profile. <our custom profile property name> - whats the recommended way to do this?
I have implemented a CollapsiblePanelExtender with a button that collapses/expands a panel. I also have a javascript function that can collapse the expanded panel when a certain condition exists somewhere else on the page.
The problem I am having is when I programatically collapse the panel, the extender is not aware, so the Collapsed property remains false and the CollapsedImage and CollapsedText are not updated. The next time I click the button, the extender is updated to a collapsed state, but nothing happens on the page because the panel was already collapsed. It is just resynchronizing the Collapsed, CollapsedImage, and CollapsedText properties to match the panel's already collapsed state.
Is there a way I can update the Collapsed, CollapsedImage, and CollapsedText properties in javascript to match the actual state of the panel?
