Web Forms :: Dynamically Changing Master Page
Aug 19, 2010
I'm working on a project that have 3 diffrent type of users with 3 diffrent master pages. I can verfiy there access level and let them view pages but after googling I came accross a tutorial form asp.net but it wasn't very helpfull the code I got listed below works only if the session is at null, It dosen't seem to pull the session value.
[Code]....
there is a class page attached to it but nothing seems to work. I've downloaded the tutorial but it wasn't any clearer than what I read.
I 'm just trying not to have to code over the joint pages.

You fetch the user's IP address and based on his/her country you redirect the user to a specific webpage. Now, how do you change the master page dynamically? This is how I am redirecting the user :-
Geolocation Error with IP Address 127.0.0.1
It's not like the user clicks some button or something and you then change the master page. I want it changed when the user is redirected, so how exactly do I go about it?
public partial class testClass: System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
if (redirected to site1)
{
Use this master page1
}
else
if (redirected to site2)
{
Use this master page2
}
}
}
So how do I check what SITE the user has been redirected to? Also HOW to apply the specific master page now that the user has been redirected?
I just need an idea how to go about it.
[EDIT] please check the code block below. How do I fetch the URL that the user has been redirected to? I actually need just the "iso3166TwoLetterCode" variable's value (see the link to my earlier question, please) and based on that will be changing the master page. I can't figure out how to fetch that value or even use that class (that's got this variable) in my testClass.
protected void Page_PreInit(object sender, EventArgs e)
{
if (user Has been redirected to www.site.in )
{
this.MasterPageFile = "master1.master";
}
if (user Has been redirected to www.site.fr )
{
this.MasterPageFile = "master2.master";
}
}

I created this master page file and in its Page_PreInit added the code to change master page at run time after detecing a visitor's country:-
Now, while researching I came across this thread that says "Setting the master page in Page_PreInit event is against the design and spirit of MVC..what is this supposed to mean ???
If not this way, how else am I supposed to change master pages at run time???

Let me set this up:I have a master page. I have a regular aspx page - this page contains a Menu and a User Control.When I click on the Menu Item, it fires my click event. This will post back. The Master Page Uses Placeholder Controls where I dynamicaly create Label Controls with information and add them to the Placeholders. These contain data with tooltips. This works great. After the Master Page and Web Page load, it will then fire the Click Event from the Menu.The problem:The Click event will update data in the database, This data may effect the values that are created on the Master Page that are placed in the Placeholder controls. I can't seem to figure out how to change that data.
What I have tried:I have created a reference to my Master Page on my Web Page. In the Click Event after I have made changes to the Database, I call the function on the master page that Creates all the data and places them in the place holders. It Runs, but nothing changes on my page.Am I going about this wrong? Is there another way of doing this? I terrible work around, would be to just reload the whole page after I do an update.

My Master Page has a heading with tabs. The code looks something like:
<CT:Tab ID="tabHome" runat="server" Url="/index.aspx" Text = "Home" Highlight="true" />
<CT:Tab ID="tabFun" runat="server" Url="/fun.html" Text = "Fun"/>
<CT:Tab ID="tabBlog" runat="server" Url="/blog" Text = "Blog"/>
I can think of two ways to control which tab is highlighted from within a user control:Have the user control implement an interface. The master page can decide which tab to highlight based on which interface is implemented, or based on a method in the interface that returns a string.In the Page_Load (or Page_Init) function, tell the master page (via FindControl or via a function in the Master Page) which control to highlight.I don't really like either of these solutions. Is there a clean way I could control which tab is highlighted from the control at design time (i.e., in the aspx file)?

In my user control I got this inline CSS in which I have only css classes... like I am not setting any attribute or whatever on some ID..got only classes like :-
.sp
{
backgrond-image :url(blah blah);
}
and so on..
nothing of the sort
#id1
{
/* set some property here*/
}
Now my question:-
Do I need to worry about system generated IDs if the CSS in my user control got only classes ? like in my page source..the divs ID changes from their original ID to something like ctl00_ContentPlaceHolder2_ctl00_Banner_divBanner after adding usercontrol and master page ...
so changing IDs shouldn't make any difference..right ??

How to Create Master Page in Code Behind Dynamically?
View 1 Replies

I am thinking that it would be better to use multipe CSS files and change them within the master page dynamically than it would be to use multiple master pages (basically one master page for each page, which defeats the purpose of the master page).
However, I do not know how to make a change to the master page before a standard apsx page that is derived from it is loaded.

Here is the thing. I have an aspx page with NO master page. I have two resource files with the same name (and specifying the language) in the App_LocalResources folder. If I do something like text="<%$ Resources:lblUser %> works fine. What I do to test it is change the browser's selected language.
But, if I do the same in a MasterPage or in a Page that is inside a MasterPage... when changing the Browser's language and refreshing... I'm still getting the default language...
I've been reading some threads about this but the situation was a little bit different.

I have a page to show a thread content, it take the ID of the thread from the query string.
depending on the ID, I show the content using the FormView control.
how could I then change the page title depending on the databinding result?
I've figured out that I can do that before the databinding in the Page_Load event, by querying the title of the thread depending on the ID from the QueryString object, but I'm wondering if I can achieve my goal during the databinding!

I recently stumbled upon this thread over at StackOverflow regarding the dynamic construction of a Master Page menu based on what roles a user is a part of. The original poster proposed a solution to his own problem, but rightfully noted that it was kludgey in that it didn't scale, but also that it violated the Separation of Concerns (SoC) model of MVC.

Can this be done?

I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.

In my web application, I have to load different Master pages depending on the user log-in information. When I say different, I mean not just the colors but a whole new look[including navigation options]. So I am using 2 Master pages [one of them is set as default] and depending on the user information the other page will be used.
I got it to work by storing the user information in a Session variable and applying the master page dynamically using the Page_PreInit event. But the issue is, if I hit the back
button, sometimes [yeah, only sometimes !!!] the master page is reset to the default page. Initially I thought it is a Session timeout issue. But it isn't, as some of the session variables still have data. Can anyone explain whats actually happening?

My Project is a normal web site, not a Web Project, and I am using VS 2005.
I am trying to define common Master Page Type in app_code which has an area to display error messages and the like. Very simple.
I added the following in app_code:
[Code]....
Also, I added the following in Master Page Source Declaration:
[Code]....
Also, I added the controls tblrowErrMsg and lblErrMsg as server controls to the Master Page.
Why I am doing this ?
This will allow me to display error messages from nearly any where inside the code in code-behined, app_code, and other core Class Projects (DLL).

We have a database with around 5000 records in it. We also have a web page that displays many of the fields. One field is an nText field and displays up to several paragraphs. My customer wants me to add those A+ and A- buttons for increasing and decreasing the font size for this field. My problem is that many of the older records have quite a bit of formatting in the field. Most of the rest contain styles dictating a font size of 12 px. Is there a way to increase and decrease the font soze of the text without modifying all the records?
Here's an example:
