Set the property of the main page from the content page and get this property value from another content page in asp.net

I have a main page with one type of property name event. Now I want to set this property on the content page, and then the property value should be available on another content page.

Is this possible with asp.net? If so, please help me.

And yes, my content page already inherits another page that is not leading.

If this property is a custom property that you added to the main page, you will need to add an ad MasterTypeto the page that includes it.

<%@ MasterType 
    virtualpath="~/Path/To/Your.master" 
%>

- , .

Page.Master.MyCustomerProperty = someValue;

: , , , ( ) , , . , "", , .

: "" . .

public event EventHandler myPropertyChanged;
public delegate void MyPropertyChanged(object sender, EventArgs e);

//...

public string MyProperty
{
    get
    {
       return _myProperty;
    }
    set
    {
        _myProperty = value;
        if (myPropertyChanged != null)
            myPropertyChanged(this, new EventArgs());
    }
}

, , :

protected void Page_Load(object sender, EventArgs e) 
{
    Page.Master.MyPropertyChanged += new EventHandler(MasterPropertyChanged);
}

protected void MasterPropertyChanged(object sender, EventArgs e) 
    //Rememeber you need the VirtualType in order for this event to be recognized
    SomeLocalValue = Page.Master.MyProperty;
}
