Can a aspx page pass a parameter to a master page?

Hello,
I would like pages that use my Master page to be able to tell the master page whether to load the wide or normal style. Based on this I will show/hide different controls and CSS files.

So can an aspx page pass a parameter to its master page?
Or does it load too late in the page cycle?

private bool isWide;
 
    protected void Page_Load(object sender, EventArgs e)
    {
 
    }
 
    public bool IsWide
    {
        get { return isWide; }
        set { isWide = value; }
    }

Hello,
I'm aware that you can register & show/hide controls and css files in the aspx pages. However I do not want to have a ton of redundant code.

i dont know about passing parameters but you definitely can access the content pages controls on the master page
the follwoing link provides u the sample for that

Hi.

Yes you can

First thing to do is to declare a of what type you MasterPage is. To do so you have to add MasterType declaration right after Page declaration in your content aspx file, like:
<%@ Page ... %>
<%@ MasterType TypeName="MyNamespace.MyMasterPage" %>

Second thing to do is to define a public property on master page (IsWide in your case)

Third thing is to set this property from content page in Page_Load event, like:
this.Master.IsWide = true;

At this point it should be Master page's responsability to load needed controls and styles.

Right, as I mentioned above. There would be a lot of redundant code if I start accessing the controls on the master page. currently I'm doing this, however it's starting to get messy because I have the same code on 50+ pages now.

It would be cleanest to say this.MasterPage.IsWide = true;

And on the masterPage PageLoad do all the special stuff.

Can I do this some how?

I don't know who you just replied to but if you have no luck with my suggestion just please tell.

Hey,
The comment above was to ragi0017
Ramuncikas - Thanks! I will try this now.

It might be tricky because I have 5 different masterpages.

In the Global.asax file I set the masterpage and themes based on a setting from a resource file.

Hello Ramuncikas ,
1 question about how to set:
<%@ MasterType TypeName="MyNamespace.MyMasterPage" %>

The master pages has this on the top:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="TechSeminar.master.cs" Inherits="MasterPages_TechSeminar" %>

What do I put for TypeName?
I would prefer to establish this on the aspx.cs code behind page. Can this be done?

thanks!

Bingo, it worked.

So, an aspx page can send a parameter to it's masterpage.

In this case the parameter hides some user controls.

thanks Ramuncikas!

aspx page:
 
ASP.FrontMasterPage master = (ASP.FrontMasterPage)this.Master;
        master.IsWide = true;
 
 
masterpage cb:
 
public partial class FrontMasterPage : System.Web.UI.MasterPage
{
 
    private bool isWide;
 
    protected void Page_Load(object sender, EventArgs e)
    {
        if (isWide)
        {
            headControl1.Visible = false;
        }
    }
 
    public bool IsWide
    {
        get { return isWide; }
        set { isWide = value; }
    }
   
}
