You can do that with some scripts on the client side. What you need to do is to add some scripts to enable/disable the state dropdownlist and textbox controls when the onchange event of the country dropdownlist is raised.

function Country_Changed()
{
var country = window.document.getElementById("ddlCountry").value;
if(country=="")
{
window.document.getElementById("ddlState").disabled = "disabled";
window.document.getElementById("txtState").disabled = "disabled";
}
else if(country=="USA")
{
window.document.getElementById("ddlState").disabled = "";
window.document.getElementById("txtState").disabled = "disabled";
}
else
{
window.document.getElementById("ddlState").disabled = "disabled";
window.document.getElementById("txtState").disabled = "";
}
}

To register the Country_Changed function for the onchange event, you can use the sample code below:

ddlCountry.Attributes.Add("onchange", "Country_Changed();");

In addition, you can also use some code on the server side to do that, but I think it is unlikely.
