access a ascx parameter in code behind

I was wondering if I could add a user control to a page with a parameter and then access that parameter in the code behiind for initiallization.

For example on my aspx page i would have somethign like.

<%@ Register TagPrefix="uc1" TagName="myMap" Src="~/Map.ascx" %>
blah 
blah 
blah
<uc1:myMap ID="myMap1" runat="server" DefaultCountry="UnitedStates"/>

How would I access the DefaultCountry parameter in my Map.ascx.cs code behind file.

If I am off base on this what is the correct implementation?

EDIT:

Figured it out

in .aspx page

<uc1:myPartnerMap ID="MyPartnerMap1" runat="server" defaultCountry="USA"/>

in .ascx.cs of the user control

private string defaultCountry;   

    public String DefaultCountry
    {
        get { return defaultCountry; }
        set { defaultCountry = value; }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            CountrySelector.SelectedValue = defaultCountry;
        }
    }

This code is enough

in .aspx page

<uc1:myPartnerMap ID="MyPartnerMap1" runat="server" DefaultCountry ="USA"/>

in .ascx.cs of the user control

public String DefaultCountry { get; set; }

The property will be initialized with the value "USA" automatically.

In this case DefaultCountry sould be a property of your user control. So you can simply access it by using this property of the user control's instance.

You would call the usercontrol first, and then the public property on the user control.

myMap1.DefaultCountry = "UnitedStates";
