Answer 1

You can determine the content page from your master page by using the ContentPlaceHolder's Page property. The following code assumes that the content place holder on your master page is called MainContent .

// Page_Load in your master page code behind file
protected void Page_Load(object sender, EventArgs e)
{
  if (this.MainContent.Page is _Default)
  {
    // The default page
  }

  if (this.MainContent.Page is About)
  {
    // The About page.
  }
}

A master page is actually a subclass of System.Web.UI.UserControl and as such it has a reference to the page through its Page property . For example, if you want to know the ASPX file and/or its folder, you can use the following code:

protected void Page_Load(object sender, EventArgs e)
{
  // Something like ~/Folder/Default.aspx
  string file = Page.AppRelativeVirtualPath;

  // Something like ~/Folder/
  string folder = Page.AppRelativeTemplateSourceDirectory;
}
