Dynamically binding headers reference of ascx in aspx page.

Question

Dynamically binding headers reference in aspx page.

 

Example:

 

I have used multiple headers reference in single page in c#. Is there any way to bind these headers dynamicaly??

<%@ Register TagPrefix="uc" TagName="SearchCountryObControl" Src="~/APIControls/SearchCountryObControl.ascx" %>
<%@ Register TagPrefix="uc" TagName="GetCompanyInfoControl" Src="~/APIControls/GetCompanyInfoControl.ascx" %>
<%@ Register TagPrefix="uc" TagName="SearchCityObControl" Src="~/APIControls/SearchCityObControl.ascx" %>
<%@ Register TagPrefix="uc" TagName="GetUserRoutingProfilesControl" Src="~/APIControls/GetUserRoutingProfilesControl.ascx" %>
<%@ Register TagPrefix="uc" TagName="GetRatePlanObControl" Src="~/APIControls/GetRatePlanObControl.ascx" %>
<%@ Register TagPrefix="uc" TagName="CompanyBilling1EControl" Src="~/APIControls/CompanyBilling1EControl.ascx" %>
<%@ Register TagPrefix="uc" TagName="GetAllProfilesControl" Src="~/APIControls/GetAllProfilesControl.ascx" %>

below the method are calling like in aspx page(note that there is no code behind):

 

at single time i used only 1 reference.

var searchCountry = new Voice.Vpbx.Api.UI.APIControls.SearchCountryObControl.SearchCountryObHelper();
var xml_response = searchCountry.GetAllCountry(lcData);
var searchCity = new Voice.Vpbx.Api.UI.APIControls.SearchCityObControl.SearchCityObHelper();
var xml_response = searchCity.GetAllInternationalCity(lcData);

is there any way to bind these reference dynamically i.e. if this page loads then all the reference are loads so i want to load the single refrence by using dynamically. Is there any best way to do?
