Access C# class in another page

[HexElffilter]

Hi folks,

I'm having difficulty accessing C# classes from other pages.

To keep this explanation simple, I have a couple of ascx pages which are loaded into an aspx page.
I have created a custom method in the ascx page that will save everything from the page controls into a database table.

ascx page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public class panels_app1 : System.Web.UI.UserControl
{
    public void AppSave()
    {
        if (Page.IsValid)
        {
            ApplicantBLL appBLL = new ApplicantBLL();

            appBLL.AddApplicant(chkHealth.Checked, chkHelp.Checked, chkTalk.Checked, ddlTitle.SelectedValue,
                    txtFirstName.Text, txtSurname.Text, ddlGender.SelectedValue, txtAddr1.Text, txtAddr2.Text,
                    txtAddr3.Text, txtAddr4.Text, txtAddr5.Text, ddlCountry.SelectedValue,
                    Convert.ToInt32(txtUKYears.Text), txtPostcode.Text, txtTel.Text, txtMobile.Text,
                    txtEMail.Text, Convert.ToDateTime(txtDOB.Text), Convert.ToInt32(txtAge.Text),
                    ddlEthnicity.SelectedValue, txtEthnicOther.Text, txtNI.Text, txtULN.Text);

            Response.Redirect("http://sqlserv1/misintranet");
        }
    }
}

aspx page:

using AjaxControlToolkit;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Apply : System.Web.UI.Page
{
    protected Control _formApp, _formCourse, _formEducation, _formRefs, _formSubmit;

    private void LoadPanels()
    {
        _formApp = Page.LoadControl("~/panels/app1.ascx");
        plhApp.Controls.Add(_formApp);

        _formCourse = Page.LoadControl("~/panels/course.ascx");
        plhCourse.Controls.Add(_formCourse);

        _formEducation = Page.LoadControl("~/panels/education.ascx");
        plhEducation.Controls.Add(_formEducation);

        _formRefs = Page.LoadControl("~/panels/references.ascx");
        plhRefs.Controls.Add(_formRefs);

        _formSubmit = Page.LoadControl("~/panels/submit.ascx");
        plhSubmit.Controls.Add(_formSubmit);
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        LoadPanels();
    }

    protected void btnSave1_Click(object sender, EventArgs e)
    {
        if (Page.IsValid)
        {
            _formApp.AppSave();
        }
    }
}

But I can't seem to access the method from the ascx page, does anyone know where I am going wrong?

OK, I've changed the top line to:

protected panels_app1 _formApp, _formCourse, _formEducation, _formRefs, _formSubmit;

But it still can't find panels_app1:

Error 1 The type or namespace name 'panels_app1' could not be found (are you missing a using directive or an assembly reference?)

You need to register the control on the page... i.e.
<%@ Register Src="~/Controls/PickForm.ascx" TagName="PickForm" TagPrefix="pop" %>

Thanks
