I read from the web.config in my global.aspx. How can I get this variable from my form?

protected void Application_Start(Object sender, EventArgs e)
{
   propertyId = ConfigurationSettings.AppSettings.Get("ID");      
}

Have you tried:

propertyId = ConfigurationSettings.AppSettings("ID");

You could do the following:

'in global.asax
protected void Application_Start(Object sender, EventArgs e)
{
   Application["propertyId"] = ConfigurationSettings.AppSettings.Get("ID");    
}

'in any webform
int x = Application["propertyId"]; //Assuming it's an integer, you get the idea

You mention the alternative of loading from the webconfig in the form itself, which is actually what I'd recommend (conditionally). Using application variables uses memory, and unless you're using this propertyId on every web form, you're wasting memory by loading it in an application variable.
