I have an MVC3 C# .Net web app. I have a popup dialog box defined in a .js file. I am trying to get the popup to display in the center of the screen. What is the property to do that. I have tries position:'absolute' but no go. Here's a snipet of my jscript code
LdapDialog = {
    /*
    * Base URL for the app. Must be set prior to calling show (ideally in _Layout.cshtml).
    */
    baseUrl: "",
    title: "Lookup:  Search by Last Name",
    width: 375,
    height: 600,
    loading: $('<img src="' + $.getUrl('Content/Images/loading.gif') + '" />'), 
    dialogContainer: $('<div></div>'),
    position: $('absolute'),
}
Any ideas?
